'''Ceramics Safety and Information'''

Overview

'''Goal'''

This is an introductory ceramics orientation and safety course designed to familiarize members and prospective members with the studio's policies, layout, and available equipment, as well as studio etiquette. The primary focus of this class is understanding the rules and procedures of the studio and tools to ensure a safe, collaborative, and productive experience for all users.

CSI attendees should leave with a clear understanding of the following:
*Safe operation of all tools and shared resources below, including appropriate cleaning
*Shared cleaning responsibilities and commitments of all Ceramics members
*How Ceramics memberships work and what their next steps are for signing up
Note that this class is required to use the ceramics space as a ceramics member. It is recommended you take this class before starting your membership to gain immediate access once you are a member. ASMBLY and Ceramics memberships are not required to take this class.

'''General Safety'''
*Dust will be present, and it is up to everyone to help to keep the dust levels down. You must clean up the areas you worked at before leaving the studio. Use the provided sponges and mops to clean up the studio. No brooms or other dry cleaning methods.
*Wearing a mask is encouraged to users comfort level
*No food allowed in the studio. No eating allowed. Closed beverages are okay.
'''Time'''

2 hours

'''Tools & Shared Resources Covered'''
*Wheels
*Extruder
*Slab Roller Table
*Sinks
*Glazing Tools
*Community Tools for Sharing
*Kiln Shelves
*Tables
*Member and education shelves
'''Materials Supplied During Class'''
*Clay (from the educational shelf)
'''Talk'''
*Welcome. Welcome CSI attendees to the space and ask them about their ceramics experience.
**Be sure to mark everyone who comes as “Attended” in NeonOne.
*Goal & General Safety. Review the goals of this training with them and emphasize the general safety considerations
*What is the CSI? This is the Ceramics Safety Information session. To be a member at ASMBLY, you also need to do a Member Orientation. Interested in volunteering? Reach out to Sid about doing a Volunteer Orientation.
*ASMBLY Culture. Talk about ASMBLY as a whole, emphasizing that it is a volunteer-run space and that all members accept responsibility for their part in maintaining a clean, friendly, and beautiful space for themselves and others. Explain the [https://wiki.asmbly.org/index.php%3Ftitle=How_to_Be_Excellent How to Be Excellent] adage.
*Memberships. Review Ceramics membership options.
**Membership Levels (include all of ASMBLY + the Ceramics Area)
***½ Shelf: $175
***Full Shelf: $250
***Top Shelf: $300
***If you have an existing ASMBLY membership, you can upgrade to one of these options for the difference between your current membership and the shelf size you want.
**Note that Ceramics memberships are additional because uniquely to this area, storage and services are included. Not only do you get a shelf, but you also get unlimited firing, which is run by a team of kiln operators. Members do NOT get to use the kilns on their own.
*Volunteering. Volunteer opportunities are available and the first step is to schedule a General Volunteer Orientation with the Volunteer Coordinator. [https://wiki.asmbly.org/index.php%3Ftitle=Volunteering_at_Asmbly You can learn more about Volunteering at ASMBLY on the wiki]. Ceramics specific information can be found on [https://wiki.asmbly.org/index.php%3Ftitle=Ceramics_Volunteer#Free_Shelf_Option Ceramics Volunteer] wiki page: 16 hours of volunteer work gets a month of access to the ceramics space if 8 of the hours are ceramics shifts (CSI or SOD). We also offer discounted memberships by trading in volunteer hours (Redeem 12 volunteer hours in any studio at ASMBLY and you can purchase ceramics shelves at the below rates: $80/half shelf, $155/full shelf, $205/top shelf)
*What’s Unique. Talk about the things that make ASMBLY unique as a ceramics space.
**21 Hour Access. You can use the space anytime you’d like from 5am - 2am everyday. Sign up on Skedda to book tool hours. Like with other areas of ASMBLY, members are limited to 25 total tool hours per week (there are some exceptions in other departments).
**Novices & Experts Welcome. After you take this training and get a membership, you can start booking time in the space, whether you’re brand new to ceramics or a seasoned pro. If you are brand new, we strongly suggest that you take a class to get the basics of wheel throwing or hand building to maximize your ability to use the space, but there is nothing stopping you from using online resources to self-teach if that is something you would prefer. If you are new, please read each of the wiki pages explaining tool use and the ceramics policy wiki before using the equipment.
'''Community Etiquette'''
*Cleaning. This is huge and should be mentioned repeatedly throughout the training. Everyone is responsible for cleaning. You are responsible for cleaning every tool and your work area after every time you use the space. You commit 5 minutes of communal cleaning for each booking (this cleaning is beyond cleaning your personal space)
**Sinks
***NO CLAY. Absolutely no pieces of clay should go down the sinks. You can dispose of the watery part of throwing water, but too much clay down the sink (even with our clay traps) will cause major plumbing problems.
***NO GLAZE. Do not put large amount of glaze down the sinks. Glaze can often contain heavy metals and other materials that pose environmental concerns.
**Trash
***Regular Trash: You can put non-clay trash in here, including if you have extra glaze that you do not plan on saving for future use. No clay in the trash! It will get heavy and it is wasteful.
***Clay. We have a DIY clay recycling station at the studio. Please dispose of unwanted clay trimmings in the communal buckets by the back sink. We recommend you recycle/reclaim your own clay and feel free to use as much of the donated clay as well.
**Community Tools
***ASMBLY offers wood tools, wire tools, needles, plastic drying bags, drying boards, glaze brushes and more for shared member use
***If you used it, CLEAN it before returning it. This means washing it and sponging it to remove clay, drying the tool, and returning it to its assigned location. DO NOT LEAVE TOOLS IN DRYING RACKS. ONLY RINSED AND WRUNG OUT SPONGES MAY REMAIN ON DRYING RACKS.
***Clean and return the throwing bats to their designated rack near the back sink
****Do not store ANYTHING on the bats, they are only for throwing
**Your Area
***Clean your own area after use with provided buckets, sponges and mops.
****Thoroughly wipe down tables, floors, and any other areas you’ve used. If you used a tool, make sure it is clean before you leave. If you used the door, clean your clay off both sides of the door.
***Rinse out your sponges and mops after use and wring out the sponge until the water runs clear into the sink, then replace where you found it (leave in the drying rack for sponges or propped for mops up so they can dry to avoid mildew)
**Material Disposal & Recycling
***Personal Recycling
****Do it! It’s a smart way to make the most of your clay purchases. Clay is infinitely recyclable as long as it is not fired. Hardie boards are available outside for this process. If left overnight, this reclamation process must take place on your personal shelf.
***Studio Clay Recycling Donations
****See the bucket area near the wheel sink. This mixed clay is first-come first served for reclaim projects!
****If bucket is full, please help your community by using it or disposing of it in the Asmbly dumpsters. Replace plastic bag in bucket
'''Tour'''

*Label your clay bags with a sharpie before putting on your shelf

*Member Shelves.
**Member shelves are offered on a first-come, first-serve basis.
**Show what a half-shelf, full-shelf, and top shelf look like.
**If you end or suspend your membership, we cannot save your shelf for you. If you come back, you’ll have to pick a shelf from what’s available at that time.
**As good practice, never touch anything on someone else’s shelf.

*Sinks & Shared Tools.
**There are two sinks and two shared tool areas in the studio.
**Remind folks about cleaning shared tools and what to not put down the sinks!

*Recycling.
**Show the clay recycling donation area near the wheel sink.
**Clay is personally recycled by members.
**Hardie boards are available outside.
**Projects must be contained to personal shelves overnight.
**Workshops and instructions to follow! Find online!

*Kilns.
**No one except the Kiln Operators should ever be in the kiln room.
**There is no limit to the number of firings for members.
**Explain usage violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio
**Drop Off / Pick Up Process
***For dry pieces ready to be fired, put it on the Greenware shelf. Fill in the Drop Off form and take a picture of your piece (see QR code on shelf). Pieces must be BONE DRY. Pieces that are still wet will be emailed by the Kiln Operators and asked to move to your shelf to dry fully. All pieces must have a maker’s mark on the piece somewhere. The Kiln Operators and Ceramic Lead have the right to delay a piece being fired if it is not ready, or deemed a risk. Communication will be provided to the owner in this instance.
***After the bisque firing, it will be put on the Bisque shelf by the Kiln Operators. You will be emailed and then have two weeks to move it to your shelf before it is disposed of.
***For glazed pieces ready to be fired, put it on the Glaze shelf. Fill in the Drop Off form and take a picture of your piece (see QR code on shelf). All pieces must have wax resist applied to the lower ¼” and bottom and remain unglazed. Pieces with multiple layers of glazing or multiple glazes must have the lower ½” and bottom wax resisted and unglazed. Pieces that are improperly glazed will be emailed by the Kiln Operators and will need to be redone before proceeding. This involves washing the piece, letting it dry, and reapplying glaze.
***After the glaze firing, it will be put on the Ready to Pickup shelf by Kiln Operators. You will be emailed and then have two weeks to move it to your shelf before it is disposed of.
***Special Note About Students: If you are a student and not a member, your teacher will put your dry items on the Greenware shelf when they’re ready to be fired. You will be notified about pick-up and can come to the studio during our Steward on Duty hours. Students may have their pieces glazed for a small additional fee or take a glaze class to learn how to do it themselves.

*Glaze.
**Direct to [https://wiki.asmbly.org/index.php?title=How_to_Glaze How to Glaze Wiki]
**Explain usage violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio
**Glazing Area Policies
**Wax Resist MUST be applied to the bottom of all pieces (including sides)
***The small brushes with the wax resist are the provided brushes
***¼” up from base must be wax resisted or taped off so that this part remains unglazed
***½” up from base must be wax resisted or taped off if using multiple glazes, or multiple layers
**Cleaning Wax Brushes
***Pick off wax resist from bristles into the Trash
***Wash the remaining small wax resist brushes off with HOT WATER, or provided alcohol
**Use small bowls provided to pour some glaze into
***DO NOT dip your brushes directly into the glaze jars.
***Label disposable cups if you leave extra glaze, keep on your personal shelf
**Cleaning Glaze Brushes
***Rinse in clay sink with water and hand soap if it’s needed
***Black may need a bit more scrubbing
***Dry brushes and return to containers
**Take the Glaze Workshop Class if you want to learn more about techniques!
**Approved Glazes
***8 Amaco Mid-fire Celadon Glazes (glossy) provided
***9 Mayco Fundamentals Underglazes provided (can be applied to greenware and bisque)
***3 Jungle Gems provided
***They can be mixed like paint to achieve other colors on the color wheel
***Other Mid-Fire Glaze approved: any Amaco Mid-fire Celadon, Amaco Satin Matte, Jungle Jems, Potter’s choice, Mayco Fundamentals Underglaze colors can be purchased at Armadillo Clay
***There is a process for glaze approval on the wiki
'''Tools'''
*Skedda. This is the tool/resource booking system for all of ASMBLY.
**Maximum Booking Times (for a single booking):
***Wheel: 5 hours
***1/2 Tables: 5 hours
**Tools and resources can be booked again after your time is up, as long as no one has booked it after you.
**Access to the extruder, glazing area, and slab roller are included with either Wheel or Table booking. These tools are meant to be shared amongst members booked in Skedda, so make an effort to share collaboratively and initiate a conversation if you need to “work in” to use a tool if someone is using it. Accommodate sharing these tools cooperatively.
**All hours count toward your 25 hour limit for the week on bookable tools.

*Wheels. We have 8 Brent CXCs. This tool is used to create consistent pieces in a variety of shapes and forms
**In this training, we do not cover how to throw on a wheel, center, etc. We just want to make sure you know how to operate the tool correctly. If you want to learn how to wheel throw, take a class!
**Every CSI attendee needs to demonstrate that they can do all of the following:
***Turn the wheels on and off
***Operator the direction switch (forward, reverse, neutral)
***Use the foot pedal (up position is off, pressed down is on and how far you press determines speed)
***Removing and rebuilding the splash pan (essential for cleaning)
**Clean Up
***Turn your wheel off and make sure the foot pedal is in the off position
***Take off splash pan
***Take it to recycling area and put things in appropriate buckets (or save scraps for yourself)
***Wash off in sinks with clay capture
***Use sponge to wipe down top and sides of the wheel head and the wheel bench, be sure to get anything that is under the wheel too!
***Put the splash pan back together
***Put the foot pedal on the wheel bench
***Put stool on to clean wheel
***Put away all your tools
***Mop your area–explain mopping technique, if you haven’t already

*Extruder: Brent Wall Mounted: This tool is used to create consistent extrusions of your choice of shape to be used to create coil built pieces. She is very expensive and can be easily damaged by leaving dry clay in it.
**Show how to operate the device and have everyone try it with no clay inside first
***Direction Selector: small yellow handled disk
****If it is at the top: the plunger can lift up
****If it is at the bottom: the plunger can be pressed down
***Plunger: rests outside of the tube on the right side of the tool
****It is easiest to maneuver the plunger with it as upright as possible and close to your body
***End Cap & Die: end cap is on the left side of the tool; dies and rubber gasket are on the extruder table
****Be sure to assemble the die as follows in the end cap:
1. Rubber Gasket, 2. Die of Choice, 3. Die Selector (if applicable)
*Do it with clay! Have everyone try extruding a small amount.
**Put the end cap on with full die assembly as noted above
**Wedge and create the large cylinder of clay to insert into the extruder tube
**Put the direction selector in the up position and lift the plunger and up and move it over to above the tube
**Put the direction selector in the down position; lower the plunger into tube
**Grip the handle of the plunder and apply a gentle, steady downward motion. Do not yank - keep it smooth and consistent.
***Note: smaller dies will require more force, but still apply consistent pressure rather than jerky motions.
**When the extruded piece is at the length you want, cut or tear it off and place that piece on your board or extruding table.
*Cleaning Procedure
**When you are finished, put the direction selector in the up position, lift the plunger up and move it back over to its resting spot (be sure the direction selector is in the down position now)
**Clean clay from all parts of the extruder - the plunger, the tube, the end cap & dies.
**Use a bucket with a sponge to clean every bit of clay off
***Place the bucket under the extruder to run water through
***Clean the extruder tube inside from top to bottom
***Clean off plunger and dies in the water bucket
**DRY CLAY will ruin this tool, so don’t be the one who leaves dry clay in it
**Return the clean end cap and dies to their storage locations

*Slab Roller: This tool makes clay into flat sheets.
**Start with a slab of clay that is about 1” thick (we’ll roll it to a final thickness of about ¼”)
**There is a light clay and dark clay side to the canvas - be sure you are using the right one. Wet sponge off any mistakes, fingerprints, transfers of the wrong clay body
**Place starting clay block between the canvas in the center
**Set the measurement gauges on both sides at the 1st height (1” or ⅞” is good)
**Feed the folded side of the canvas into the roller.
**Remove your fingers from the roller area
**Start to slowly turn the wagon wheel
***Turn the wheel the direction you want the slab to go in a smooth consistent motion
**Roll entire canvas through, open canvas to check slab position and flip directions or over on the canvas as needed to not squeeze out or to reach desired end shape
**Decrease the height setting by ⅛” increments until you reach the desired height of the slab
**Let each person get a turn at rolling and flipping a slab
**Troubleshooting: If clay gets close to edge of canvas, reverse the wheel direction, flip back the canvas, and cut the slab off before continuing
**Important: If clay gets on the roller wheel, this is a pain to clean
***Get a damp sponge to remove the clay off while it is still moist - do not let the clay fully dry out and do not soak the roller with water. Use needle tool if you must.
'''Clean Up'''
*Have everyone clean up together, including:
**Mopping around the wheels-Flipping the mop, using the squeegee, rinsing, wringing, and cleaning the sponge after until the water runs clear
**Cleaning the extruder parts and body
**Leaving the slab roller canvas open
**Sponging down the work surfaces where clay was wedged or used
**Dry and return any tools used in the process (ONLY SPONGES REMAIN ON DRYING RACKS)
*Have an issue? Use the Problem Reports QR code.
**Point out the QR codes throughout the studio to report tools not left clean, someone using a tool during your booking, etc.
*Finish with a reminder that ALL levels of skill are welcome to the Studio and there will be Studio Stewards hours, where someone will be present to help out in case they have questions.
**Current Steward Shifts: Tuesdays 6-8, Saturdays 12-4
**The Asmbly Event Calendar is the most up to date schedule for SOD times.
Thank them for visiting and suggest they bring more friends! We still have more shelves currently available!

Thank you!

[[Category:Ceramics]]

= Introduction =
Asmbly Policies outlined in the Member Handbook, [[Member Handbook#General%20Info|HERE]] apply to ALL shop areas including Ceramics. However Ceramics has some additional policies specific to the studio that are outlined below.

Check out the essential rules on How to Be Excellent, [[How to Be Excellent|HERE]]

Ceramics Safety & Information (CSI) is the required free class you must take before access to the studio with membership is granted. In addition to the CSI, you are required to take a Glazing Workshop class before firing glazed pieces. These are separate from the required Asmbly Orientation & Facility Tour.

We are all caretakers of the shared space, so the cleanliness and maintenance is up to you!

= Usage Areas =
Refer the Equipment-Specific time limits [[Member Handbook#Equipment-specific%20time%20limits|HERE]]

==== Tools ====
You must reserve time for each tool you plan to use in Skedda. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use. Leave yourself at least 15 minutes to clean your space and another 5 minutes of time to contribute to the cleanliness of our community studio.

* Pottery Wheels: 8 machines available: Max booking is 5 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Wheel in Skedda up to 5 more hours
You must book yourself as a User if you plan on sitting at a Handbuilding Table, regardless of tool booking. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use. Leave yourself at least 15 minutes to clean your space and another 5 minutes of time to contribute to the cleanliness of our community studio.

* Handbuilding Tables: 8 Users can Book up to 5 hours of time between 4 tables (2 Users/table)
** It is not a specific table spot, just that you plan on using some table space
** If you will need to use an entire table, plan to book 2 half tables so that others are aware of the space available before they arrive
** When your time ends, check Skedda.
** If it is not booked, you can rebook yourself as a User in Skedda up to 5 more hours
Use of the glazing area, slab roller, and extruder are included with booking of either a Pottery Wheel or 1/2 Handbuilding Table. Please use these collaboratively, if multiple users need to utilize during the same time period. Be friendly and initiate conversations to best share access to these spaces. Expect these to be crowded spaces and work efficiently!

==== Community Tools/Areas ====

* Please clean all tools you use from the communal tools and return them CLEAN to their storage location
* Dish racks are for SPONGES, bats and wareboards
* Place brown paper on handbuilding tables if applying glaze at these tables
** Glaze should be kept from contaminating the canvas and wooden table surfaces

= Safety =

* Ceramic Dust: Silica dust is going to be present in the studio

** Use your own personal discretion
** NEVER make another person feel bad for wearing a mask.
** NEVER turn the Blue Ox Filtration off
* NEVER use a broom or vacuum. WATER is the best way to safely clean up clay.
* If there is dry clay on the canvas topped tables, wet it with water and remove with a wet sponge
** Do NOT scrape dry clay, it will kick up unnecessary dust
** Do NOT blow clay
* NO FOOD in the Studio, you risk eating glaze accidentally (Closed beverage containers OK)
* No sanding bisque pieces inside the studio.
* We have a Blue Ox Air filtration system installed in the studio to help cut back on particulates in the air.

== Kiln Check-In Procedures ==
Currently Asmbly Makerspace is not limiting the number of pieces, or firings, you can participate in each month. We aim for a 1-2 week turnaround, but this could be longer or shorter depending on many factors. The Kiln Operators reserve the right to hold or delay a piece if it is not dry enough, or they feel the member needs to correct something to be safe to fire. The Kiln Operators will communicate with you when your piece is out of the Kiln, or before the firing if there are any issues. They can be reached at: [[Mailto:kilnops@asmbly.org|kilnops@asmbly.org]]

Firing Sign In Process

# Follow the QR Code to a Google Form for each type of firing
## Check in ALL your pieces with just one Google Form.
## Fill out ONE form for Bisque, and a NEW form for Glaze

2. Fill out one WHITE paper slip for EACH of your pieces

# This will serve as a physical record the Kiln Operators can track as things come in and out of the Kilns.

'''Example:''' You have 7 pieces: 4 for Bisque, and 3 for Glaze. You need to fill out 2 Google Forms (1 for each type of firing), and 7 white paper slips (1 to stay with each piece).

= Firing System =
We are aiming at Asmbly to have a turnaround of 1-2 weeks after you have placed your bone dry pieces on the shelf, to receive a fired piece. Dry pieces submitted to be fired will be put in the kilns on a first come, first in basis. There could be other factors, like not being dry enough, needing to prioritize a class, not enough pieces to fill a kiln, or other reasons that could potentially cause delays. All firing and kilns will be run by the Kiln Operators.

1. As of 4/22/2025 the Kilns will be fired to:

# Bisque Fired at Cone 04 (~1900-1940℉)
# Low-fire Glaze at Cone 04 (~1940℉)
# Mid-fire Glaze or Stoneware at Cone 6 (~2200℉).

2. Special temperature firings may occur at the discretion of the Lead Kiln Operator

3. ALL pieces must have wax resist on the bottom to avoid getting stuck to the shelves or supports

# If you want to put glaze all over and risk it getting stuck to the support, you must discuss this with the Lead Kiln Operators and be aware it may cause damage to your piece

3. We recommend you leave ¼”-½” around the base of your pieces to avoid sticking to the kiln shelves

# This is not required at this time, just strongly advised
# If serious issues arise it may be made an official policy
# The Kiln Operators reserve the right to ask you to make any corrections to your

==== Usage Violations ====

* Usage of unapproved clay & glazes will be recorded and not allowed
** It may result in damage to your or other’s pieces
** Kiln damage
* Repeated reported violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio

= Clay Body & Glaze Approval System =
Asmbly is a community of makers and creators, as such we want to honor the experimental nature that comes with clay and crafting. Ceramics has an endless amount of processes and abilities when it comes to glazing and firing, and we have created a system that strives to be fair and balanced to non-approved clay and glazes, while also maintaining the safety of member’s pieces and the Kilns at Asmbly.

# As of 4/22/2025 the Kilns will be fired to:
## Bisque Fired at Cone 04 (~1900-1940℉)
## Low-fire Glaze at Cone 04 (~1940℉)
## Mid-fire Glaze at Cone 6 (~2200℉).
# Clay or glazes that need a cooler or hotter maturation temperature will currently not be accepted.
## This could change in the future at the discretion of Asmbly
## Special projects may be considered
# Clay and glaze test pieces will be checked in the same way as other pieces, with the “Kiln Check In Form”, but will be placed on the Test Shelves
# We will not accept Glazes with Lead in any form in the studio
# The Skutt Kiln (Helios) is the test kiln
# Your piece may wait for some time, until we have a full load, and is fully dry before being fired

# This is up to the discretion of the Kiln Operators

Asmbly Makerspace is not responsible for any cracks that could occur before, during, or after the firing process.

It is rare, but if any damage to our kiln or kiln furniture is directly caused by your piece, you will be responsible for replacement or repair charges.

=== Clay Body ===
Non-Approved clay bodies must go through the following steps to be approved

# Bisque Fire:
## Please make a small piece out of your clay body, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
## Please allow it to dry, and then dry some more, before placing on the Greenware Test Shelf
### The longer you let it dry, the less time it will spend waiting to go in to the kiln
### We will not accept pieces that are still wet
# If it does not melt, crack excessively or otherwise seem dangerous it will be approved to be used along with our other approved clay bodies.

=== Glaze - approval of new commercial Glazes ===
Non-Approved glazes must go through the following steps to be approved

# Glaze Fire:
## Please make a small piece, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
#### If you do not have a piece to test your glaze on, a vertical test tile will be provided to you by Asmbly made of Cinco Blanco
## Glaze your piece with the glaze you are testing.
### Leave 1” of unglazed ceramic at the bottom to test if it runs or drips excessively
### Leave ¼” - ½” unglazed if using a provided vertical test tile
## Please apply the same glaze technique on the test piece you plan to apply on the actual piece, in order to get an accurate test.
### Same number of layers, colors, overlaps of glazes, etc.
# If it does not melt, crack excessively, craze past your liking, or otherwise seem dangerous it will be approved to be allowed in with the other glazes

= Discipline/Violations Policy =
Asmbly Discipline Policy can be found [[Member Handbook#Discipline|HERE]]

Note: The people enforcing Asmbly policies are volunteers and it's not the most fun job. Failure to comply when approached about a policy violation is very serious. Show your fellow members kindness and respect when receiving redirection. Maintaining a cooperative community space at Asmbly is very important to us and ignoring the redirection of an appointed leader in the space is a serious violation.

How to Glaze

2025-12-23T20:41:08Z

EEatx: /* Before You Begin:Our glazing and cleaning procedures MUST be followed if you intend to use our communal products, glazing spaces, and kiln firing. */

== Before You Begin: Our glazing and cleaning procedures MUST be followed if you intend to use our communal products, glazing spaces, and kiln firing. ==

* DO NOT dip brushes directly into glaze jars. Pour out glaze into provided bowls or cups
** Keep 2 oz plastic cups of glaze labelled and on personal shelves
* DO NOT return poured out glaze to glaze jars--these must remain uncontaminated
* DO NOT overglaze your piece--it will be rejected. 2-3 coats is all that is necessary.
* DO NOT use unapproved glazes (process listed below for approval of glazes)
* You must WAIT for each layer to fully dry before added another glaze layer
* DO use wax resist on the bottom of your piece, 1/4" if using one glaze, 1/2" if using multiple glazes. Wipe off any glaze that dripped onto this area before loading it onto the kiln shelves

== Glazing: Step-by-Step ==
Below is a list of the procedures members need to make sure to follow, to guarantee a safe glazing process. Incorrect glazing may damage the member's own piece, other members' pieces inside a kiln, the kiln itself, and may even put at risk the safety of kiln operators and studio members.

Pieces that don't follow these instructions may be rejected by the kiln operators and placed in the "Rejected" shelf.

'''In-House Dip Glazes:'''

* '''Ensure your piece is bisque fired''' and free from dust BEFORE glazing (wipe gently with a damp sponge)
*'''Apply wax resist to the bottom and 1/2" space up sides''' of your piece using the small, blue designated-wax brushes provided at the glazing station
**''Do not use your own brushes for wax resist''
**'''Clean wax brushes''': Pick wax off into trash, then rinse in HOT water or use provided alcohol
*'''Stir glaze in bucket vigorously with the brush'''
**scrub dense build up on the edges into the mix until you have an even consistency
*'''Dip for 1-2 seconds'''
*'''Rest''' piece on top of a glazing table or paper-covered handbuilding table as the glaze layer dries
*'''WAIT until the glaze is evenly dried before dipping again'''
**Look for an even color, discoloration means that the glaze is not dry.
*'''Stir glaze AGAIN''' scrubbing dense build up on the edges into the mix until you have an even consistency
*'''Dip AGAIN''' if coverage is not complete (1-2 seconds)
*'''Wipe off excess glaze from wax-resisted areas'''
*'''Place piece on HOUSE DIP GLAZE SHELF'''
*'''Prepare yourself''' ''for the wonderous, mystery of glaze''

'''Amaco Celadon Glazes on Table in Pints:'''
#'''Ensure your piece is bisque fired''' and free from dust BEFORE glazing (wipe gently with a damp sponge)
#'''Apply wax resist to the bottom and 1/4" space up sides''' of your piece using the small designated wax brushes provided
#*''Do not use your own brushes for wax resist''
#*'''Clean wax brushes''': Pick wax off into trash, then rinse in HOT water
#'''Stir your glaze thoroughly''' before use — glaze ingredients settle and must be evenly mixed
#'''Pour glaze into a small bowl''' before brushing. '''DO NOT DIP brushes''' directly into the main glaze jars
#'''Apply glaze evenly'''
#* 1–3 coats depending on glaze type
#* Avoid over-applying to prevent drips and runs
#* Reserve 1/2" of unglazed area at the bottom of your piece if:
#** thickly applied;
#** if it is a fast running type of glaze (fluxes, rutiles, are examples of fast running glazes. Read the manufacturers labels and they will let you know)
#** or if you are layering more than one type of glaze
#'''WAIT for each glaze layer to dry''' before applying again.
#'''Leave the bottom of the piece unglazed'''
#* Minimum 1/4" clearance (or 1" if for glaze testing)
#* Wipe foot completely clean to avoid kiln shelf damage
#'''Clean glaze brushes''': Rinse in the sink; use hand soap if needed — black glaze may require extra scrubbing
#'''Dry and return brushes to their designated containers'''
#'''Label your piece''' clearly if it's part of glaze testing
#'''Place on the Glaze Fire shelf''' and use check in form for kiln shelves
Please Note:
* Make sure your glaze is '''studio-approved or has passed testing'''
* '''Improper glazing or unlabeled pieces''' may be held back from firing and will be placed in the "rejected" shelf

== Glaze Testing & Approval Policy ==
To protect the integrity of our kilns, the safety of our members, and the quality of everyone’s work, we enforce a strict glaze approval policy. Only clearly defined and approved materials are permitted for use in the studio.
----

=== What Is Allowed ===
We only accept '''commercially manufactured glazes''', in the following forms:

* '''Pre-Mixed Commercial Glazes''' Liquid glazes sold ready-to-use by established ceramic glaze manufacturers (e.g., Amaco, Mayco, Laguna etc.).
* '''Studio-Approved Commercial Dry Glazes''' Powdered commercial dip glazes that are reconstituted '''under conditional supervision''' within the studio. These glazes must:
** Come directly from a commercial distributor
** Be mixed by or in coordination with designated studio personnel
** Receive prior approval from Seth or Perla
Please Note:

'''Members are not allowed to bring in, store, or mix dry commercial glaze powders on their own''', even if the materials are from reputable sources. All glaze mixing must be supervised and approved in advance.
----

=== What Is Not Allowed ===
The following are strictly '''prohibited''' in the studio:

* Any '''homemade''', '''member-formulated''', or '''DIY glaze recipes''', regardless of their source (e.g., books, online, ceramic blogs)
* Any mixture of raw glaze materials (oxides, frits, fluxes, etc.) sourced independently by members
* Any glaze materials or combinations that do '''not appear as a finished product in a commercial glaze bottle'''
* '''Mixing glaze powders''' outside the studio, including in outdoor common areas like the parking lot

To be clear: '''If it isn’t sold as a finished glaze product or mixed under the supervision of approved studio personnel, it is not allowed.'''
----

=== Mixing Policy ===

* '''No unsupervised mixing of glaze materials is allowed''', including reconstituting commercial dry dip glazes.
* Approved commercial dry glazes may be mixed only:
** Under the supervision of Seth, Perla, or another designated person
** In controlled and designated areas with proper PPE and ventilation
* Members are not permitted to bring in raw glaze materials or mix their own glazes in any studio or public area.

----

=== Glaze Testing ===

* All test firings must be approved and scheduled independently from regular kiln loads.
* A '''separate test kiln''' will be used when appropriate.
* The '''topmost studio shelves''' are designated for placing test pieces (bisque or glaze tests) and will be clearly labeled.

----

=== Approval & Communication ===
All materials not currently on the approved list must be reviewed and explicitly approved '''before''' use.

For approvals, contact:

* '''Seth White''' – seth.white@asmbly.org
* '''Perla Darnell''' – perla.darnell@asmbly.org

Email is the preferred and most reliable method of communication.
----

=== How to Test a Glaze ===

# '''Use a test piece''' (under 6" x 6" x 6") ''or'' request a vertical test tile from Asmbly (Cinco Blanco clay)
# '''Apply your glaze fully''' using the same number of coats, layering, and techniques you intend for your final work
#* Leave '''1" unglazed''' at the bottom of ceramic test pieces
#* Leave '''1/4"–1/2" unglazed''' on provided vertical test tiles
# '''Label''' the piece or tile with your name and the glaze name
# '''Place on the Glaze Test Shelf''' near the kilns
# '''Wait for glaze fire''' (scheduled based on kiln availability)
# '''Results will be assessed''' for running, crazing, blistering, or risk to kiln/kiln furniture

'''Please Note:'''

* You may lose the test piece
* Approved glazes will be added to our studio list.

== Approved Glazes at Asmbly ==
Asmbly is a community of makers, so we encourage exploration and creativity. Below are some of the glazes approved for use in our studio. This doesn't mean we carry them all, but it means you can use them. You will find all the available glazes in the glazing area. If the tube has a cookie test tile on top, it is one of the glazes we consistently restock; otherwise, it was a donation and can be used by anyone in the shop, but we don't carry it and repurchase it constantly.

If you are going to glaze a large piece with more layers than indicated by the instructions in the product, or if you plan to layer two different glazes, please use a test tile first to be sure it will not run and stick to the kiln.

Here is the list of pre-approved glazes:

==== Underglazes (Mayco Brand) ====

* '''Versatile & Food Safe''': Use for full coverage or in designs on clay, greenware, or bisque. Food safe when covered with a clear glaze.
* '''Firing Range''': Cone 6 - Cone 10 (We fire to cone 5).
* '''Application''': Shake well, apply 2-3 coats to wet clay or bisque, avoiding glaze pooling in textured areas.
* '''Firing''': Fire to cone 04, then apply clear glaze and fire to cone 06/05 for earthenware or cone 5-10 for stoneware.

----

==== Celadon Glazes (Amaco Brand) ====

* '''Translucent & Glossy Finish''': Ideal for highlighting texture on your pieces.
* '''Firing Range''': Cone 5 - Cone 6 (Food safe).
* '''Available at Asmbly''': Some colors available for members to use at no extra cost. Other colors can be brought in without testing.
* '''Application''': Follow the manufacturer’s instructions for number of coats. No need to mix with other glazes.

----

==== Potter's Choice Glazes (Amaco Brand) ====

* '''Fluid Colors & Effects''': Great for smooth or textured pieces. Not food safe.
* '''Firing Range''': Cone 5 - Cone 6.
* '''Available at Asmbly''': Some samples available, but members must purchase other colors.
* '''Application''': Test glazes first on a vertical test tile. If combining glazes, test on a tile before applying to pieces.
* '''Note''': Results can vary due to glaze interaction, especially when layering.

----

==== Satin Matte Glazes (Amaco Brand) ====

* '''Soft Satin Feel''': Semi-opaque glazes that break over texture and edges.
* '''Firing Range''': Cone 5 - Cone 6 (Food safe).
* '''Available at Asmbly''': Some colors in-house for free. Members can bring in other colors without testing.
* '''Application''': Follow the manufacturer’s instructions. No need to mix with other glazes.

----

==== Jungle Gems Glazes (Mayco Brand) ====

* '''Colorful & Textured''': Glass frit bursts create intricate patterns.
* '''Firing Range''': Cone 5 - Cone 6.
* '''Food Safety''': Not 100% food safe due to potential crazing.
* '''Available at Asmbly''': Some colors available for members to use, but members must purchase others.
* '''Application''': Shake well and apply 2-3 coats to bisque. Stir frequently, as crystals can settle. Avoid heavy application at the bottom of pieces to prevent glaze melting onto kiln shelves.
* '''Note''': The glass crystals bloom during firing, creating unique results each time.

== Summary ==

* Only studio-approved commercial glazes are permitted — '''no exceptions'''
* Dry commercial glazes may only be mixed '''under supervision''' — members cannot mix on their own or off-site
* '''No homemade recipes''', experimental blends, or member-sourced raw materials are allowed
* All glaze testing is separate from regular firings and must be placed on '''designated shelves'''
* Email '''Seth White (seth.white@asmbly.org)''' or '''Perla Darnell (perla.darnell@asmbly.org)''' for all material approval and testing coordination

#'''Ensure your piece is bisque fired''' and free from dust BEFORE glazing (wipe gently with a damp sponge)
#'''Apply wax resist to the bottom and 1/4" space up sides''' of your piece using the small designated wax brushes provided
#*''Do not use your own brushes for wax resist''
#*'''Clean wax brushes''': Pick wax off into trash, then rinse in HOT water
#'''Stir your glaze thoroughly''' before use — glaze ingredients settle and must be evenly mixed
#'''Pour glaze into a small bowl''' before brushing. '''DO NOT DIP brushes''' directly into the main glaze jars
#'''Apply glaze evenly'''
#* 1–3 coats depending on glaze type
#* Avoid over-applying to prevent drips and runs
#* Reserve 1/2" of unglazed area at the bottom of your piece if:
#** thickly applied;
#** if it is a fast running type of glaze (fluxes, rutiles, are examples of fast running glazes. Read the manufacturers labels and they will let you know)
#** or if you are layering more than one type of glaze
#'''WAIT for each glaze layer to dry''' before applying again.
#'''Leave the bottom of the piece unglazed'''
#* Minimum 1/4" clearance (or 1" if for glaze testing)
#* Wipe foot completely clean to avoid kiln shelf damage
#'''Clean glaze brushes''': Rinse in the sink; use hand soap if needed — black glaze may require extra scrubbing
#'''Dry and return brushes to their designated containers'''
#'''Label your piece''' clearly if it's part of glaze testing
#'''Place on the Glaze Fire shelf''' and use check in form for kiln shelves
Please Note:
* Make sure your glaze is '''studio-approved or has passed testing'''
* '''Improper glazing or unlabeled pieces''' may be held back from firing and will be placed in the "rejected" shelf

== Glaze Testing & Approval Policy ==
To protect the integrity of our kilns, the safety of our members, and the quality of everyone’s work, we enforce a strict glaze approval policy. Only clearly defined and approved materials are permitted for use in the studio.
----

=== What Is Allowed ===
We only accept '''commercially manufactured glazes''', in the following forms:

* '''Pre-Mixed Commercial Glazes''' Liquid glazes sold ready-to-use by established ceramic glaze manufacturers (e.g., Amaco, Mayco, Laguna etc.).
* '''Studio-Approved Commercial Dry Glazes''' Powdered commercial dip glazes that are reconstituted '''under conditional supervision''' within the studio. These glazes must:
** Come directly from a commercial distributor
** Be mixed by or in coordination with designated studio personnel
** Receive prior approval from Seth or Perla
Please Note:

'''Members are not allowed to bring in, store, or mix dry commercial glaze powders on their own''', even if the materials are from reputable sources. All glaze mixing must be supervised and approved in advance.
----

=== What Is Not Allowed ===
The following are strictly '''prohibited''' in the studio:

* Any '''homemade''', '''member-formulated''', or '''DIY glaze recipes''', regardless of their source (e.g., books, online, ceramic blogs)
* Any mixture of raw glaze materials (oxides, frits, fluxes, etc.) sourced independently by members
* Any glaze materials or combinations that do '''not appear as a finished product in a commercial glaze bottle'''
* '''Mixing glaze powders''' outside the studio, including in outdoor common areas like the parking lot

To be clear: '''If it isn’t sold as a finished glaze product or mixed under the supervision of approved studio personnel, it is not allowed.'''
----

=== Mixing Policy ===

* '''No unsupervised mixing of glaze materials is allowed''', including reconstituting commercial dry dip glazes.
* Approved commercial dry glazes may be mixed only:
** Under the supervision of Seth, Perla, or another designated person
** In controlled and designated areas with proper PPE and ventilation
* Members are not permitted to bring in raw glaze materials or mix their own glazes in any studio or public area.

----

=== Glaze Testing ===

* All test firings must be approved and scheduled independently from regular kiln loads.
* A '''separate test kiln''' will be used when appropriate.
* The '''topmost studio shelves''' are designated for placing test pieces (bisque or glaze tests) and will be clearly labeled.

----

=== Approval & Communication ===
All materials not currently on the approved list must be reviewed and explicitly approved '''before''' use.

For approvals, contact:

* '''Seth White''' – seth.white@asmbly.org
* '''Perla Darnell''' – perla.darnell@asmbly.org

Email is the preferred and most reliable method of communication.
----

=== How to Test a Glaze ===

# '''Use a test piece''' (under 6" x 6" x 6") ''or'' request a vertical test tile from Asmbly (Cinco Blanco clay)
# '''Apply your glaze fully''' using the same number of coats, layering, and techniques you intend for your final work
#* Leave '''1" unglazed''' at the bottom of ceramic test pieces
#* Leave '''1/4"–1/2" unglazed''' on provided vertical test tiles
# '''Label''' the piece or tile with your name and the glaze name
# '''Place on the Glaze Test Shelf''' near the kilns
# '''Wait for glaze fire''' (scheduled based on kiln availability)
# '''Results will be assessed''' for running, crazing, blistering, or risk to kiln/kiln furniture

'''Please Note:'''

* You may lose the test piece
* Approved glazes will be added to our studio list.

== Approved Glazes at Asmbly ==
Asmbly is a community of makers, so we encourage exploration and creativity. Below are some of the glazes approved for use in our studio. This doesn't mean we carry them all, but it means you can use them. You will find all the available glazes in the glazing area. If the tube has a cookie test tile on top, it is one of the glazes we consistently restock; otherwise, it was a donation and can be used by anyone in the shop, but we don't carry it and repurchase it constantly.

If you are going to glaze a large piece with more layers than indicated by the instructions in the product, or if you plan to layer two different glazes, please use a test tile first to be sure it will not run and stick to the kiln.

Here is the list of pre-approved glazes:

==== Underglazes (Mayco Brand) ====

* '''Versatile & Food Safe''': Use for full coverage or in designs on clay, greenware, or bisque. Food safe when covered with a clear glaze.
* '''Firing Range''': Cone 6 - Cone 10 (We fire to cone 5).
* '''Application''': Shake well, apply 2-3 coats to wet clay or bisque, avoiding glaze pooling in textured areas.
* '''Firing''': Fire to cone 04, then apply clear glaze and fire to cone 06/05 for earthenware or cone 5-10 for stoneware.

----

==== Celadon Glazes (Amaco Brand) ====

* '''Translucent & Glossy Finish''': Ideal for highlighting texture on your pieces.
* '''Firing Range''': Cone 5 - Cone 6 (Food safe).
* '''Available at Asmbly''': Some colors available for members to use at no extra cost. Other colors can be brought in without testing.
* '''Application''': Follow the manufacturer’s instructions for number of coats. No need to mix with other glazes.

----

==== Potter's Choice Glazes (Amaco Brand) ====

* '''Fluid Colors & Effects''': Great for smooth or textured pieces. Not food safe.
* '''Firing Range''': Cone 5 - Cone 6.
* '''Available at Asmbly''': Some samples available, but members must purchase other colors.
* '''Application''': Test glazes first on a vertical test tile. If combining glazes, test on a tile before applying to pieces.
* '''Note''': Results can vary due to glaze interaction, especially when layering.

----

==== Satin Matte Glazes (Amaco Brand) ====

* '''Soft Satin Feel''': Semi-opaque glazes that break over texture and edges.
* '''Firing Range''': Cone 5 - Cone 6 (Food safe).
* '''Available at Asmbly''': Some colors in-house for free. Members can bring in other colors without testing.
* '''Application''': Follow the manufacturer’s instructions. No need to mix with other glazes.

----

==== Jungle Gems Glazes (Mayco Brand) ====

* '''Colorful & Textured''': Glass frit bursts create intricate patterns.
* '''Firing Range''': Cone 5 - Cone 6.
* '''Food Safety''': Not 100% food safe due to potential crazing.
* '''Available at Asmbly''': Some colors available for members to use, but members must purchase others.
* '''Application''': Shake well and apply 2-3 coats to bisque. Stir frequently, as crystals can settle. Avoid heavy application at the bottom of pieces to prevent glaze melting onto kiln shelves.
* '''Note''': The glass crystals bloom during firing, creating unique results each time.

== Summary ==

* Only studio-approved commercial glazes are permitted — '''no exceptions'''
* Dry commercial glazes may only be mixed '''under supervision''' — members cannot mix on their own or off-site
* '''No homemade recipes''', experimental blends, or member-sourced raw materials are allowed
* All glaze testing is separate from regular firings and must be placed on '''designated shelves'''
* Email '''Seth White (seth.white@asmbly.org)''' or '''Perla Darnell (perla.darnell@asmbly.org)''' for all material approval and testing coordination

Ceramics Policy

2025-12-23T20:13:16Z

EEatx: Blue Ox warning, 2 oz cups, fixed link to glaze page

[[Category:Ceramics]]

= Introduction =
Asmbly Policies outlined in the Member Handbook, [[Member Handbook#General%20Info|HERE]] apply to ALL shop areas including Ceramics. However Ceramics has some additional policies specific to the studio that are outlined below.

Check out the essential rules on How to Be Excellent, [[How to Be Excellent|HERE]]

Ceramics Safety & Information (CSI) is the required free class you must take before access to the studio with membership is granted. In addition to the CSI, you are required to take a Glazing Workshop class before firing glazed pieces. These are separate from the required Asmbly Orientation & Facility Tour.

We are all caretakers of the shared space, so the cleanliness and maintenance is up to you!

= Usage Areas =
Refer the Equipment-Specific time limits [[Member Handbook#Equipment-specific%20time%20limits|HERE]]

==== Tools ====
You must reserve time for each tool you plan to use in Skedda. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use. Leave yourself at least 15 minutes to clean your space and another 5 minutes of time to contribute to the cleanliness of our community studio.

* Pottery Wheels: 8 machines available: Max booking is 5 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Wheel in Skedda up to 5 more hours
You must book yourself as a User if you plan on sitting at a Handbuilding Table, regardless of tool booking. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use. Leave yourself at least 15 minutes to clean your space and another 5 minutes of time to contribute to the cleanliness of our community studio.

* Handbuilding Tables: 8 Users can Book up to 5 hours of time between 4 tables (2 Users/table)
** It is not a specific table spot, just that you plan on using some table space
** If you will need to use an entire table, plan to book 2 half tables so that others are aware of the space available before they arrive
** When your time ends, check Skedda.
** If it is not booked, you can rebook yourself as a User in Skedda up to 5 more hours
Use of the glazing area, slab roller, and extruder are included with booking of either a Pottery Wheel or 1/2 Handbuilding Table. Please use these collaboratively, if multiple users need to utilize during the same time period. Be friendly and initiate conversations to best share access to these spaces. Expect these to be crowded spaces and work efficiently!

==== Community Tools/Areas ====

* Please clean all tools you use from the communal tools and return them CLEAN to their storage location
* Dish racks are for SPONGES, bats and wareboards
* Place brown paper on handbuilding tables if applying glaze at these tables
** Glaze should be kept from contaminating the canvas and wooden table surfaces

= Safety =

* Ceramic Dust: Silica dust is going to be present in the studio
** It is highly recommended you wear a mask while in the studio for prolonged and repetitive periods; especially while cleaning up!
** Use your own personal discretion
** NEVER make another person feel bad for wearing a mask.
** NEVER turn the Blue Ox Filtration off
* NEVER use a broom or vacuum. WATER is the best way to safely clean up clay.
* If there is dry clay on the canvas topped tables, wet it with water and remove with a wet sponge
** Do NOT scrape dry clay, it will kick up unnecessary dust
** Do NOT blow clay
* NO FOOD in the Studio, you risk eating glaze accidentally (Closed beverage containers OK)
* No sanding bisque pieces inside the studio.
* We have a Blue Ox Air filtration system installed in the studio to help cut back on particulates in the air.
** Members are NOT allowed to turn the filtration system off, it is a Policy violation
** If you are a staff or a volunteer, and you absolutely need to turn the filtration system off, you must turn it on again before you leave.

== Kiln Check-In Procedures ==
Currently Asmbly Makerspace is not limiting the number of pieces, or firings, you can participate in each month. We aim for a 1-2 week turnaround, but this could be longer or shorter depending on many factors. The Kiln Operators reserve the right to hold or delay a piece if it is not dry enough, or they feel the member needs to correct something to be safe to fire. The Kiln Operators will communicate with you when your piece is out of the Kiln, or before the firing if there are any issues. They can be reached at: [[Mailto:kilnops@asmbly.org|kilnops@asmbly.org]]

Firing Sign In Process

# Follow the QR Code to a Google Form for each type of firing
## Check in ALL your pieces with just one Google Form.
## Fill out ONE form for Bisque, and a NEW form for Glaze

2. Fill out one WHITE paper slip for EACH of your pieces

# This will serve as a physical record the Kiln Operators can track as things come in and out of the Kilns.

'''Example:''' You have 7 pieces: 4 for Bisque, and 3 for Glaze. You need to fill out 2 Google Forms (1 for each type of firing), and 7 white paper slips (1 to stay with each piece).

= Firing System =
We are aiming at Asmbly to have a turnaround of 1-2 weeks after you have placed your bone dry pieces on the shelf, to receive a fired piece. Dry pieces submitted to be fired will be put in the kilns on a first come, first in basis. There could be other factors, like not being dry enough, needing to prioritize a class, not enough pieces to fill a kiln, or other reasons that could potentially cause delays. All firing and kilns will be run by the Kiln Operators.

1. As of 4/22/2025 the Kilns will be fired to:

# Bisque Fired at Cone 04 (~1900-1940℉)
# Low-fire Glaze at Cone 04 (~1940℉)
# Mid-fire Glaze or Stoneware at Cone 6 (~2200℉).

2. Special temperature firings may occur at the discretion of the Lead Kiln Operator

3. ALL pieces must have wax resist on the bottom to avoid getting stuck to the shelves or supports

# If you want to put glaze all over and risk it getting stuck to the support, you must discuss this with the Lead Kiln Operators and be aware it may cause damage to your piece

3. We recommend you leave ¼”-½” around the base of your pieces to avoid sticking to the kiln shelves

# This is not required at this time, just strongly advised
# If serious issues arise it may be made an official policy
# The Kiln Operators reserve the right to ask you to make any corrections to your

==== Usage Violations ====

* Usage of unapproved clay & glazes will be recorded and not allowed
** It may result in damage to your or other’s pieces
** Kiln damage
* Repeated reported violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio

= Clay Body & Glaze Approval System =
Asmbly is a community of makers and creators, as such we want to honor the experimental nature that comes with clay and crafting. Ceramics has an endless amount of processes and abilities when it comes to glazing and firing, and we have created a system that strives to be fair and balanced to non-approved clay and glazes, while also maintaining the safety of member’s pieces and the Kilns at Asmbly.

# As of 4/22/2025 the Kilns will be fired to:
## Bisque Fired at Cone 04 (~1900-1940℉)
## Low-fire Glaze at Cone 04 (~1940℉)
## Mid-fire Glaze at Cone 6 (~2200℉).
# Clay or glazes that need a cooler or hotter maturation temperature will currently not be accepted.
## This could change in the future at the discretion of Asmbly
## Special projects may be considered
# Clay and glaze test pieces will be checked in the same way as other pieces, with the “Kiln Check In Form”, but will be placed on the Test Shelves
# We will not accept Glazes with Lead in any form in the studio
# The Skutt Kiln (Helios) is the test kiln
# Your piece may wait for some time, until we have a full load, and is fully dry before being fired

# This is up to the discretion of the Kiln Operators

Asmbly Makerspace is not responsible for any cracks that could occur before, during, or after the firing process.

It is rare, but if any damage to our kiln or kiln furniture is directly caused by your piece, you will be responsible for replacement or repair charges.

=== Clay Body ===
Non-Approved clay bodies must go through the following steps to be approved

# Bisque Fire:
## Please make a small piece out of your clay body, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
## Please allow it to dry, and then dry some more, before placing on the Greenware Test Shelf
### The longer you let it dry, the less time it will spend waiting to go in to the kiln
### We will not accept pieces that are still wet
# If it does not melt, crack excessively or otherwise seem dangerous it will be approved to be used along with our other approved clay bodies.

=== Glaze - approval of new commercial Glazes ===
Non-Approved glazes must go through the following steps to be approved

# Glaze Fire:
## Please make a small piece, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
#### If you do not have a piece to test your glaze on, a vertical test tile will be provided to you by Asmbly made of Cinco Blanco
## Glaze your piece with the glaze you are testing.
### Leave 1” of unglazed ceramic at the bottom to test if it runs or drips excessively
### Leave ¼” - ½” unglazed if using a provided vertical test tile
## Please apply the same glaze technique on the test piece you plan to apply on the actual piece, in order to get an accurate test.
### Same number of layers, colors, overlaps of glazes, etc.
# If it does not melt, crack excessively, craze past your liking, or otherwise seem dangerous it will be approved to be allowed in with the other glazes

EEatx: Added glazing workshop to wiki

'''GLAZING WORKSHOP @ Asmbly Ceramics'''

'''Course Description:'''

Bring your bisque-fired pieces to life in this hands-on Glazing Workshop! In this session,

you’ll learn the fundamentals of glazing: how to apply glaze cleanly, testing different

techniques, and experimenting with colors. The instructor will cover best practices for

dipping, pouring, brushing, and layering glazes to create unique effects. This workshop is

perfect for beginners and those looking to refine their glazing skills. All materials and tools

are provided. Students may bring bisque fired pieces from Asmbly classes, or pieces made

during Asmbly open studio hours.

'''Learning Objectives'''

After completing this course students should be able to:

● Use studio glazes and tools to create unique finishes.

● Apply even coats, layer glazes, and experiment with combinations.

● Properly prepare your pieces for firing.

'''Student Responsibilities'''

1. Wear closed toe shoes, have long hair tied back, and no dangling clothing or jewelry.

2. Bring a piece that has been bisque fired and is ready to be glazed. Pieces must have been

made at Asmbly and must be made from Asmbly- approved materials.

'''I. PART ONE / Getting Started'''

'''Glazing Basics'''

• Start Clean: You want to wash your bisque work before you start. Fingerprints,

oils, clay dust and debris seen and unseen can contaminate the surface of your

work. This can result in bare spots, pockets or bubbles in the glaze, trash suspended

in the glaze or discoloration. A clean wet cloth, brush, or even compressed air will

do.

• Stay Clean: Make sure that you lay out cardboard or paper on whatever surface

you are using. Glazes that spill dry quickly and is hard to tell from clay. Someone

could easily add this to their clay body during wedging or working. This will create

a pockmark or bubble with some explosive possibility. Make sure you have a sponge

ready for clean up as well as your glaze sponge.

'''Tools and Materials'''

You will need: Lazy Susan, wax, wax brushes, glaze brushes, condiment containers, bowl ½

full water, small moist sponge, large dry sponge.

'''III. PART TWO / Glaze Techniques'''

'''Applying Glaze'''

* '''Preparing your base:''' Anywhere that your work touches the tabletop will need to

be wax coated to prevent glaze from adhering to the body of the work. Be aware

that dried glaze can become embedded in this wax, and will have the same

consequences. You want to ensure that you leave AT THE VERY LEAST 1/8th of an

inch of space from the bottom of the work to where the glaze begins (1/4 or more

on fluxes and house dips). Glaze is silicate and mineral components becoming glass.

Glass is fluid and gravity is inevitable and it is always sad to have to scrape a work,

or possibly destroy it, to remove it from a kiln shelf. Simply using the wax brush,

brush the wax resist anywhere you do not want glaze to be. If you want a very

clean line, I recommend tape first, then wax over the edge, then removing the tape.

Tape also resists glaze, but presents its own challenges, mostly with adherence

during the application of other glazes and removal.

'''• Prepare your glaze:''' If you are using a commercial glaze from a jar, first ensure

the lid is sealed tightly. Next you are going to shake it vigorously vertically and

horizontally, left and right, up and down. Open the jar. If it still looks marbled or the

color uneven then seal the jar and shake is violently without losing your grip.

Sometimes you may want to use the back of a CLEAN brush handle to scrape the

chunky sludge off the sides. This is vital because it may affect glazes as the mineral

components will clump to the sides. If the glaze is overly thick or muddy, you can

add water CAUTIOUSLY! Tablespoons are preferred over the tap. Once your glaze

has a nice consistency, pour out a small amount into the condiment cup. Try not to

over fill, as you can add more over time, and glaze does dry quickly.

'''• Prepare your brush:''' You want to moisten your brush first. I recommend spraying

it with the pressure washer into the sink. This ensures you have no glaze

contamination. Then you want to remove any excessive moisture. Thats where your

large dry sponge comes into play. Have your bowl of water handy to rinse your

brush when it becomes chalky. A dry brush glazes the brush rather that the work.

• Apply the Glaze: Load your brush by dipping one side of the bristles, with a light

scoop of glaze when retracting. This will give you a bead at the tip or edge of your

brush. Touch this point to your work. As the glaze touches, but before your bristles

make full contact, pull the brush into the direction of coverage. This should deliver a

thin to solid stroke. Do not brush back and forth if you can avoid it! Attempt to

deliver your strokes in one direction. Once your intended area is covered YOU MUST

WAIT until the first layer is completely and utterly dry. There is no hurrying this

process. Fans and heat guns will seal in moisture and cause problems. The color of

the glaze will be an even chalky when it is dry enough for another layer. For most

glazes you want a minimum of two layers for them to work properly. Some

specialty glazes want only one layer for maximum effect. Three layers is pretty

standard and safe if you are unfamiliar with the glaze. Four or more layers is

pushing it and is most likely to just pour off of your work and onto someone else’s.

Standard glaze is alchemy and has no respect for color theory. Underglaze is the

most paint like of the glazes. Underglaze will not stick to the kiln shelf, so it can be

applied anywhere. The primary color in underglaze will make any standard glaze

more vibrant and opaque If brushed underneath. It can be mixed according to color

wheel (sorta) and can be thinned to be used as a wash or applied as a water color

to great effect.

'''• Dip Glaze Application:''' A simpler and stricter form of application, it’s a much

faster process. I again mention the consideration of generous wax spacing on the

bottom of the vessel to be dipped. Open the bucket and take your scrub brush and

scrape the sides of the walls into the mix. Ensure you break up any sedimentation in

the bottom of the bucket, especially where the wall meets the bottom. Wisk and stir

until the glaze have an even color and consistency. With the tongs or hook dip your

work in one to two seconds, with possibly one swish around if it has a lot of detail.

Let the excess drip back into the bucket. When it is done dripping you may want to

set the work down on its waxed base because you are going to have to WAIT for it

to dry completely before dipping it again. Dips are typically thicker and if one dip

looks consistent, you are probably good. If it appears to be a minor spot missed, use

a glaze brush to do a spot touchup. It’s fine to dip in one color then another or over

a commercial glaze IF YOUR GLAZE IS COMPLETELY DRY FIRST!

'''• Tidy:''' Wipe glaze off of the bottom of your work. When the wax melts away any

glaze bits will fuse somewhere they are not supposed to, or turn to glass splatter or

beads.

'''Preparing for Firing'''

'''• Considerations in construction:''' Informing your work with the consideration of

your glaze application matters immensely the more complex your work is. The first

and simplest is the cookie. A coaster for your work that takes the work into

consideration for propping it up for complete flow or absorbing runoff. You can also

make kiln furniture that will hold your work in a way to make the spot with no

glaze invisible. This can be made from the same clay body you are using, and they

can be reused a few times. Making kiln furniture out of porcelain or other cone 10

clays will give you a lot more milage. For jewelry applications heat resistant rods and

furniture can be purchase (just don’t forget to wax your holes.) This is strictly for

LOW FIRE. Another thing of note: Low fire kiln furniture uses metal points, allowing

for more complete glazing with only a few pinholes.

'''• Glaze Type Awareness:''' There are so many glazes and more are constantly being

added. They do different things at different temperatures. We typically run a Cone 5

glaze, with the regular Cone 04 low fire. We can fire Cone 10 but that is primarily

for porcelain, which we see little of. Your jars of glaze will say what cone your

glaze is meant to be fired at. There is a lot of small print on these jars you should

attend to. Jungle Gems doesn’t loudly tell you it is best at a low fire with 1-2 coats

just as Stoneware doesn’t tell you that you need at least cone 6 to match the

example tile. This can lead to glazes that don’t fully flow and turn into sharp

bubbles and flakes, or glazes that run right off of your work and right onto the

shelf. Some washes (mostly metal) fill in the pores of your work, making those

portions covered repellent to glaze. A little bit of flux can cause glaze to flow

dramatically and unexpectedly. Rather than dissuade people from embracing all this

magic, we have a shelf system designed to make sure your work gets processed

without damage or delay.

'''• Commercial Glaze:''' any standard glaze that doesn’t do anything weird. Rutile and

Honey Flux types are borderline here. Jungle Gems as well, but you’re really missing

out not doing them at low fire.

'''• Specialty Glaze:''' Englobes, crawl glazes, cobblestones, added fluxes, textures or any

other strangeness that does more than lay down flat.

'''• House Dip:''' Did you dip it in our bucket? Put it on this shelf even if it has a

commercial glaze on it.

'''• Test Glaze:''' Almost all commercial lead-free glazes are on the table, but we do like

to have a test tile as a sample if we haven’t seen it before. Anything mixed after

purchase or categorized previously as a specialty glaze must go through this

process.

'''• Reglazing:''' I enjoy reglazing work that I am disappointed in or for specific effects.

This is a challenging process with lots of potential for ruining work and trashing kiln

shelves. Once your work has been glaze fired it becomes resistant to glaze. First off,

the pores are filled with glaze. However, if you fire a bisqued, unglazed work at

cone five, or just again really, you will get a color change and the pores will still

shrink becoming resistant to glaze. Any application of glaze over glaze should be

expected to run, flowing much further that the glaze underneath. To apply glaze

over glaze you must still moisten your brush. Rather than brushing on the glaze you

will have to dab cautiously. This will be slow and tedious as the glaze will take

much longer to dry. It is very likely that dry glaze will flake off on its way to the

kiln. Supposedly hairspray will solve this adherence issue, but I haven’t verified it

myself. Honestly, if you are reglazing, you should drop any expectations now and

embrace the chaos.

'''• Kiln Form and Slip:''' Use your phone to activate the QR code and fill in the form.

Please take and attach a picture of your work. This form will give you a kiln ID

number. Apply this number to a slip to put with each of your works and circle all

the items that apply to your work. Please add any notes the operators should be

aware of.

'''Cleaning Your Space'''

Clean glaze spills, wash brushes, and organize tools to keep the studio ready for the next

group.

== Kiln Check-In Procedures ==
Currently Asmbly Makerspace is not limiting the number of pieces, or firings, you can participate in each month. We aim for a 1-2 week turnaround, but this could be longer or shorter depending on many factors. The Kiln Operators reserve the right to hold or delay a piece if it is not dry enough, or they feel the member needs to correct something to be safe to fire. The Kiln Operators will communicate with you when your piece is out of the Kiln, or before the firing if there are any issues. They can be reached at: [[Mailto:kilnops@asmbly.org|kilnops@asmbly.org]]

Firing Sign In Process

# Follow the QR Code to a Google Form for each type of firing
## Check in ALL your pieces with just one Google Form.
## Fill out ONE form for Bisque, and a NEW form for Glaze

2. Fill out one WHITE paper slip for EACH of your pieces

# This will serve as a physical record the Kiln Operators can track as things come in and out of the Kilns.

'''Example:''' You have 7 pieces: 4 for Bisque, and 3 for Glaze. You need to fill out 2 Google Forms (1 for each type of firing), and 7 white paper slips (1 to stay with each piece).

= Firing System =
We are aiming at Asmbly to have a turnaround of 1-2 weeks after you have placed your bone dry pieces on the shelf, to receive a fired piece. Dry pieces submitted to be fired will be put in the kilns on a first come, first in basis. There could be other factors, like not being dry enough, needing to prioritize a class, not enough pieces to fill a kiln, or other reasons that could potentially cause delays. All firing and kilns will be run by the Kiln Operators.

1. As of 4/22/2025 the Kilns will be fired to:

# Bisque Fired at Cone 04 (~1900-1940℉)
# Low-fire Glaze at Cone 04 (~1940℉)
# Mid-fire Glaze or Stoneware at Cone 6 (~2200℉).

2. Special temperature firings may occur at the discretion of the Lead Kiln Operator

3. ALL pieces must have wax resist on the bottom to avoid getting stuck to the shelves or supports

# If you want to put glaze all over and risk it getting stuck to the support, you must discuss this with the Lead Kiln Operators and be aware it may cause damage to your piece

3. We recommend you leave ¼”-½” around the base of your pieces to avoid sticking to the kiln shelves

# This is not required at this time, just strongly advised
# If serious issues arise it may be made an official policy
# The Kiln Operators reserve the right to ask you to make any corrections to your

==== Usage Violations ====

* Usage of unapproved clay & glazes will be recorded and not allowed
** It may result in damage to your or other’s pieces
** Kiln damage
* Repeated reported violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio

= Clay Body & Glaze Approval System =
Asmbly is a community of makers and creators, as such we want to honor the experimental nature that comes with clay and crafting. Ceramics has an endless amount of processes and abilities when it comes to glazing and firing, and we have created a system that strives to be fair and balanced to non-approved clay and glazes, while also maintaining the safety of member’s pieces and the Kilns at Asmbly.

# As of 4/22/2025 the Kilns will be fired to:
## Bisque Fired at Cone 04 (~1900-1940℉)
## Low-fire Glaze at Cone 04 (~1940℉)
## Mid-fire Glaze at Cone 6 (~2200℉).
# Clay or glazes that need a cooler or hotter maturation temperature will currently not be accepted.
## This could change in the future at the discretion of Asmbly
## Special projects may be considered
# Clay and glaze test pieces will be checked in the same way as other pieces, with the “Kiln Check In Form”, but will be placed on the Test Shelves
# We will not accept Glazes with Lead in any form in the studio
# The Skutt Kiln (Helios) is the test kiln
# Your piece may wait for some time, until we have a full load, and is fully dry before being fired

# This is up to the discretion of the Kiln Operators

Asmbly Makerspace is not responsible for any cracks that could occur before, during, or after the firing process.

It is rare, but if any damage to our kiln or kiln furniture is directly caused by your piece, you will be responsible for replacement or repair charges.

=== Clay Body ===
Non-Approved clay bodies must go through the following steps to be approved

# Bisque Fire:
## Please make a small piece out of your clay body, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
## Please allow it to dry, and then dry some more, before placing on the Greenware Test Shelf
### The longer you let it dry, the less time it will spend waiting to go in to the kiln
### We will not accept pieces that are still wet
# If it does not melt, crack excessively or otherwise seem dangerous it will be approved to be used along with our other approved clay bodies.

=== Glaze ===
Non-Approved glazes must go through the following steps to be approved

# Glaze Fire:
## Please make a small piece, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
#### If you do not have a piece to test your glaze on, a vertical test tile will be provided to you by Asmbly made of Cinco Blanco
## Glaze your piece with the glaze you are testing.
### Leave 1” of unglazed ceramic at the bottom to test if it runs or drips excessively
### Leave ¼” - ½” unglazed if using a provided vertical test tile
## Please apply the same glaze technique on the test piece you plan to apply on the actual piece, in order to get an accurate test.
### Same number of layers, colors, overlaps of glazes, etc.
# If it does not melt, crack excessively, craze past your liking, or otherwise seem dangerous it will be approved to be allowed in with the other glazes

= Discipline/Violations Policy =
Asmbly Discipline Policy can be found [[Member Handbook#Discipline|HERE]]

Note: The people enforcing Asmbly policies are volunteers and it's not the most fun job. Failure to comply when approached about a policy violation is very serious. Show your fellow members kindness and respect when receiving redirection. Maintaining a cooperative community space at Asmbly is very important to us and ignoring the redirection of an appointed leader in the space is a serious violation.

How to Glaze

2025-11-05T00:58:11Z

EEatx: /* Glazing: Step-by-Step */ in-house glaze process added

== Before You Begin: ==

* Our glazing and cleaning procedures MUST be followed if you intend to use our communal products, glazing spaces, and kiln firing.
* DO NOT dip brushes directly into glaze jars--pour out glaze into provided bowls or cups,
* DO NOT return poured out glaze to glaze jars--these must remain uncontaminated, label remnant glaze in plastic cups
* DO NOT overglaze your piece--it will be rejected
* DO NOT use unapproved glazes (process listed below for approval of glazes)
* WAIT for each layer to fully dry before added another glazing
* DO use wax resist on the bottom of your piece, 1/4" if using one glaze, 1/2" if using multiple glazes and wipe off any glaze that dripped onto this area before loading it onto the kiln shelves

== Glazing: Step-by-Step ==
Below is a list of the procedures members need to make sure to follow, to guarantee a safe glazing process. Incorrect glazing may damage the member's own piece, other members' pieces inside a kiln, the kiln itself, and may even put at risk the safety of kiln operators and studio members.

Pieces that don't follow these instructions may be rejected by the kiln operators and placed in the "Rejected" shelf.

'''In-House Dip Glazes:'''

* '''Ensure your piece is bisque fired''' and free from dust BEFORE glazing (wipe gently with a damp sponge)
*'''Apply wax resist to the bottom and 1/4" space up sides''' of your piece using the small designated wax brushes provided
**''Do not use your own brushes for wax resist''
**'''Clean wax brushes''': Pick wax off into trash, then rinse in HOT water
*'''Stir glaze in bucket vigorously with the brush,''' scrub dense build up on the edges into the mix until you have an even consistency
*'''Dip for 1-2 seconds'''
*'''WAIT until the glaze is evenly dried before dipping again.''' Look for an even color, discoloration means that the glaze is not dry.
*'''Stir AGAIN''' scrubbing dense build up on the edges into the mix until you have an even consistency
*'''Dip AGAIN''' if coverage is not complete
*'''Wipe off excess glaze from wax-resisted areas'''
*'''Place piece on HOUSE DIP GLAZE SHELF'''
*'''Prepare yourself''' ''for the wonderous, mystery of glaze''

'''Amaco Celadon Glazes on Table in Pints:'''
#'''Ensure your piece is bisque fired''' and free from dust BEFORE glazing (wipe gently with a damp sponge)
#'''Apply wax resist to the bottom and 1/4" space up sides''' of your piece using the small designated wax brushes provided
#*''Do not use your own brushes for wax resist''
#*'''Clean wax brushes''': Pick wax off into trash, then rinse in HOT water
#'''Stir your glaze thoroughly''' before use — glaze ingredients settle and must be evenly mixed
#'''Pour glaze into a small bowl''' before brushing. Do '''not dip brushes''' directly into the main glaze jars
#'''Apply glaze evenly'''
#* 1–3 coats depending on glaze type
#* Avoid over-applying to prevent drips and runs.
#* Reserve 1/2" of unglazed area at the bottom of your piece if:
#** thickly applied;
#** if it is a fast running type of glaze (fluxes, rutiles, are examples of fast running glazes. Read the manufacturers labels and they will let you know)
#** or if you are layering more than one type of glaze
#'''WAIT for each glaze layer to dry''' before applying again.
#'''Leave the bottom of the piece unglazed'''
#* Minimum 1/4" clearance (or 1" if for glaze testing)
#* Wipe foot completely clean to avoid kiln shelf damage
#'''Clean glaze brushes''': Rinse in the sink; use hand soap if needed — black glaze may require extra scrubbing
#'''Dry and return brushes to their designated containers'''
#'''Label your piece''' clearly if it's part of glaze testing
#'''Place on the Glaze Fire shelf''' and use check in form for kiln shelves
Please Note:
* Make sure your glaze is '''studio-approved or has passed testing'''
* '''Improper glazing or unlabeled pieces''' may be held back from firing and will be placed in the "rejected" she

== Glaze Testing & Approval Policy ==
To protect the integrity of our kilns, the safety of our members, and the quality of everyone’s work, we enforce a strict glaze approval policy. Only clearly defined and approved materials are permitted for use in the studio.
----

=== What Is Allowed ===
We only accept '''commercially manufactured glazes''', in the following forms:

* '''Pre-Mixed Commercial Glazes''' Liquid glazes sold ready-to-use by established ceramic glaze manufacturers (e.g., Amaco, Mayco, Laguna etc.).
* '''Studio-Approved Commercial Dry Glazes''' Powdered commercial dip glazes that are reconstituted '''under conditional supervision''' within the studio. These glazes must:
** Come directly from a commercial distributor
** Be mixed by or in coordination with designated studio personnel
** Receive prior approval from Seth or Perla
Please Note:

'''Members are not allowed to bring in, store, or mix dry commercial glaze powders on their own''', even if the materials are from reputable sources. All glaze mixing must be supervised and approved in advance.
----

=== What Is Not Allowed ===
The following are strictly '''prohibited''' in the studio:

* Any '''homemade''', '''member-formulated''', or '''DIY glaze recipes''', regardless of their source (e.g., books, online, ceramic blogs)
* Any mixture of raw glaze materials (oxides, frits, fluxes, etc.) sourced independently by members
* Any glaze materials or combinations that do '''not appear as a finished product in a commercial glaze bottle'''
* '''Mixing glaze powders''' outside the studio, including in outdoor common areas like the parking lot

To be clear: '''If it isn’t sold as a finished glaze product or mixed under the supervision of approved studio personnel, it is not allowed.'''
----

=== Mixing Policy ===

* '''No unsupervised mixing of glaze materials is allowed''', including reconstituting commercial dry dip glazes.
* Approved commercial dry glazes may be mixed only:
** Under the supervision of Seth, Perla, or another designated person
** In controlled and designated areas with proper PPE and ventilation
* Members are not permitted to bring in raw glaze materials or mix their own glazes in any studio or public area.

----

=== Glaze Testing ===

* All test firings must be approved and scheduled independently from regular kiln loads.
* A '''separate test kiln''' will be used when appropriate.
* The '''topmost studio shelves''' are designated for placing test pieces (bisque or glaze tests) and will be clearly labeled.

----

=== Approval & Communication ===
All materials not currently on the approved list must be reviewed and explicitly approved '''before''' use.

For approvals, contact:

* '''Seth White''' – seth.white@asmbly.org
* '''Perla Darnell''' – perla.darnell@asmbly.org

Email is the preferred and most reliable method of communication.
----

=== How to Test a Glaze ===

# '''Use a test piece''' (under 6" x 6" x 6") ''or'' request a vertical test tile from Asmbly (Cinco Blanco clay)
# '''Apply your glaze fully''' using the same number of coats, layering, and techniques you intend for your final work
#* Leave '''1" unglazed''' at the bottom of ceramic test pieces
#* Leave '''1/4"–1/2" unglazed''' on provided vertical test tiles
# '''Label''' the piece or tile with your name and the glaze name
# '''Place on the Glaze Test Shelf''' near the kilns
# '''Wait for glaze fire''' (scheduled based on kiln availability)
# '''Results will be assessed''' for running, crazing, blistering, or risk to kiln/kiln furniture

'''Please Note:'''

* You may lose the test piece
* Approved glazes will be added to our studio list.

== Approved Glazes at Asmbly ==
Asmbly is a community of makers, so we encourage exploration and creativity. Below are some of the glazes approved for use in our studio. This doesn't mean we carry them all, but it means you can use them. You will find all the available glazes in the glazing area. If the tube has a cookie test tile on top, it is one of the glazes we consistently restock; otherwise, it was a donation and can be used by anyone in the shop, but we don't carry it and repurchase it constantly.

If you are going to glaze a large piece with more layers than indicated by the instructions in the product, or if you plan to layer two different glazes, please use a test tile first to be sure it will not run and stick to the kiln.

Here is the list of pre-approved glazes:

==== Underglazes (Mayco Brand) ====

* '''Versatile & Food Safe''': Use for full coverage or in designs on clay, greenware, or bisque. Food safe when covered with a clear glaze.
* '''Firing Range''': Cone 6 - Cone 10 (We fire to cone 6).
* '''Application''': Shake well, apply 2-3 coats to wet clay or bisque, avoiding glaze pooling in textured areas.
* '''Firing''': Fire to cone 04, then apply clear glaze and fire to cone 06/05 for earthenware or cone 5-10 for stoneware.

----

==== Celadon Glazes (Amaco Brand) ====

* '''Translucent & Glossy Finish''': Ideal for highlighting texture on your pieces.
* '''Firing Range''': Cone 5 - Cone 6 (Food safe).
* '''Available at Asmbly''': Some colors available for members to use at no extra cost. Other colors can be brought in without testing.

----

==== Potter's Choice Glazes (Amaco Brand) ====

* '''Fluid Colors & Effects''': Great for smooth or textured pieces. Not food safe.
* '''Firing Range''': Cone 5 - Cone 6.
* '''Available at Asmbly''': Some samples available, but members must purchase other colors.
* '''Application''': Test glazes first on a vertical test tile. If combining glazes, test on a tile before applying to pieces.
* '''Note''': Results can vary due to glaze interaction, especially when layering.

----

==== Satin Matte Glazes (Amaco Brand) ====

* '''Soft Satin Feel''': Semi-opaque glazes that break over texture and edges.
* '''Firing Range''': Cone 5 - Cone 6 (Food safe).
* '''Available at Asmbly''': Some colors in-house for free. Members can bring in other colors without testing.
* '''Application''': Follow the manufacturer’s instructions. No need to mix with other glazes.

----

==== Jungle Gems Glazes (Mayco Brand) ====

* '''Colorful & Textured''': Glass frit bursts create intricate patterns.
* '''Firing Range''': Cone 5 - Cone 6.
* '''Food Safety''': Not 100% food safe due to potential crazing.
* '''Available at Asmbly''': Some colors available for members to use, but members must purchase others.
* '''Application''': Shake well and apply 2-3 coats to bisque. Stir frequently, as crystals can settle. Avoid heavy application at the bottom of pieces to prevent glaze melting onto kiln shelves.
* '''Note''': The glass crystals bloom during firing, creating unique results each time.

== Summary ==

* Only studio-approved commercial glazes are permitted — '''no exceptions'''
* Dry commercial glazes may only be mixed '''under supervision''' — members cannot mix on their own or off-site
* '''No homemade recipes''', experimental blends, or member-sourced raw materials are allowed
* All glaze testing is separate from regular firings and must be placed on '''designated shelves'''
* Email '''Seth White (seth.white@asmbly.org)''' or '''Perla Darnell (perla.darnell@asmbly.org)''' for all material approval and testing coordination

Ceramics Policy

2025-10-29T23:07:34Z

EEatx: /* Mid-fire Glazes Currently in Studio for Members & Classes to use: */ removed cost per glaze cup

[[Category:Ceramics]]

= Introduction =
Asmbly Policies outlined in the Member Handbook, [[Member Handbook#General%20Info|HERE]] apply to ALL shop areas including Ceramics. However Ceramics has some additional policies specific to the studio that are outlined below.

Check out the essential rules on How to Be Excellent, [[How to Be Excellent|HERE]]

Ceramics Safety & Information (CSI) is the required free class you must take before access to the studio with membership is granted. This is separate from the required Orientation & Facility Tour.

We are all caretakers of the shared space, so the cleanliness and maintenance is up to you!

= Usage Areas =
Refer the Equipment-Specific time limits [[Member Handbook#Equipment-specific%20time%20limits|HERE]]

==== Tools ====
You must reserve time for each tool you plan to use in Skedda. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Pottery Wheels: 8 machines available: Max booking is 5 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Wheel in Skedda up to 5 more hours
You must book yourself as a User if you plan on sitting at a Handbuilding Table, regardless of tool booking. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Handbuilding Tables: 8 Users can Book up to 5 hours of time between 4 tables (2 Users/table)
** It is not a specific table spot, just that you plan on using some table space
** When your time ends, check Skedda.
** If it is not booked you can rebook yourself as a User in Skedda up to 5 more hours
Use of the glazing area, slab roller, and extruder are included with booking of either a Pottery Wheel or Handbuilding Table. Please use these collaboratively, if multiple users need to utilize during the same time period. Be friendly and initiate conversations to best share access to these spaces.

==== Community Tools/Areas ====

* Please clean all tools you use from the communal tools and return to their storage location.
* Place brown paper on handbuilding tables if applying glaze
** Glaze should be kept from contaminating the canvas table surfaces

= Safety =

* Ceramic Dust: Silica dust is going to be present in the studio
** It is highly recommended you wear a mask while in the studio for prolonged and repetitive periods; especially while cleaning up!
** Use your own personal discretion
** NEVER make another person feel bad for wearing a mask.
* NEVER use a broom, WATER is the best way to safely clean up clay.
* If there is dry clay on the canvas topped tables, wet it with water to remove
** Do NOT scrape dry clay, it will kick up unnecessary dust
* NO FOOD in the Studio, you risk eating glaze accidentally (Closed beverage containers OK)
* No sanding bisque pieces inside the studio.
* We have a Blue Ox Air filtration system installed in the studio to help cut back on particulates in the air.
** Members are not allowed to turn the filtration system off without asking for permission.

== Kiln Check-In Procedures ==
Currently Asmbly Makerspace is not limiting the number of pieces, or firings, you can participate in each month. We aim for a 1-2 week turnaround, but this could be longer or shorter depending on many factors. The Kiln Operators reserve the right to hold or delay a piece if it is not dry enough, or they feel the member needs to correct something to be safe to fire. The Kiln Operators will communicate with you when your piece is out of the Kiln, or before the firing if there are any issues. They can be reached at: [[Mailto:kilnops@asmbly.org|kilnops@asmbly.org]]

Firing Sign In Process

# Follow the QR Code to a Google Form for each type of firing
## Check in ALL your pieces with just one Google Form.
## Fill out ONE form for Bisque, and a NEW form for Glaze

2. Fill out one WHITE paper slip for EACH of your pieces

# This will serve as a physical record the Kiln Operators can track as things come in and out of the Kilns.

'''Example:''' You have 7 pieces: 4 for Bisque, and 3 for Glaze. You need to fill out 2 Google Forms (1 for each type of firing), and 7 white paper slips (1 to stay with each piece).

= Firing System =
We are aiming at Asmbly to have a turnaround of 1-2 weeks after you have placed your bone dry pieces on the shelf, to receive a fired piece. Dry pieces submitted to be fired will be put in the kilns on a first come, first in basis. There could be other factors, like not being dry enough, needing to prioritize a class, not enough pieces to fill a kiln, or other reasons that could potentially cause delays. All firing and kilns will be run by the Kiln Operators.

1. As of 4/22/2025 the Kilns will be fired to:

# Bisque Fired at Cone 04 (~1900-1940℉)
# Low-fire Glaze at Cone 04 (~1940℉)
# Mid-fire Glaze or Stoneware at Cone 6 (~2200℉).

2. Special temperature firings may occur at the discretion of the Lead Kiln Operator

3. ALL pieces must have wax resist on the bottom to avoid getting stuck to the shelves or supports

# If you want to put glaze all over and risk it getting stuck to the support, you must discuss this with the Lead Kiln Operators and be aware it may cause damage to your piece

3. We recommend you leave ¼”-½” around the base of your pieces to avoid sticking to the kiln shelves

# This is not required at this time, just strongly advised
# If serious issues arise it may be made an official policy
# The Kiln Operators reserve the right to ask you to make any corrections to your

==== Usage Violations ====

* Usage of unapproved clay & glazes will be recorded and not allowed
** It may result in damage to your or other’s pieces
** Kiln damage
* Repeated reported violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio

= Clay Body & Glaze Approval System =
Asmbly is a community of makers and creators, as such we want to honor the experimental nature that comes with clay and crafting. Ceramics has an endless amount of processes and abilities when it comes to glazing and firing, and we have created a system that strives to be fair and balanced to non-approved clay and glazes, while also maintaining the safety of member’s pieces and the Kilns at Asmbly.

# As of 4/22/2025 the Kilns will be fired to:
## Bisque Fired at Cone 04 (~1900-1940℉)
## Low-fire Glaze at Cone 04 (~1940℉)
## Mid-fire Glaze at Cone 6 (~2200℉).
# Clay or glazes that need a cooler or hotter maturation temperature will currently not be accepted.
## This could change in the future at the discretion of Asmbly
## Special projects may be considered
# Clay and glaze test pieces will be checked in the same way as other pieces, with the “Kiln Check In Form”, but will be placed on the Test Shelves
# We will not accept Glazes with Lead in any form in the studio
# The Skutt Kiln (Helios) is the test kiln
# Your piece may wait for some time, until we have a full load, and is fully dry before being fired

# This is up to the discretion of the Kiln Operators

Asmbly Makerspace is not responsible for any cracks that could occur before, during, or after the firing process.

It is rare, but if any damage to our kiln or kiln furniture is directly caused by your piece, you will be responsible for replacement or repair charges.

=== Clay Body ===
Non-Approved clay bodies must go through the following steps to be approved

# Bisque Fire:
## Please make a small piece out of your clay body, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
## Please allow it to dry, and then dry some more, before placing on the Greenware Test Shelf
### The longer you let it dry, the less time it will spend waiting to go in to the kiln
### We will not accept pieces that are still wet
# If it does not melt, crack excessively or otherwise seem dangerous it will be approved to be used along with our other approved clay bodies.

=== Glaze ===
Non-Approved glazes must go through the following steps to be approved

# Glaze Fire:
## Please make a small piece, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
#### If you do not have a piece to test your glaze on, a vertical test tile will be provided to you by Asmbly made of Cinco Blanco
## Glaze your piece with the glaze you are testing.
### Leave 1” of unglazed ceramic at the bottom to test if it runs or drips excessively
### Leave ¼” - ½” unglazed if using a provided vertical test tile
## Please apply the same glaze technique on the test piece you plan to apply on the actual piece, in order to get an accurate test.
### Same number of layers, colors, overlaps of glazes, etc.
# If it does not melt, crack excessively, craze past your liking, or otherwise seem dangerous it will be approved to be allowed in with the other glazes

= Discipline/Violations Policy =
Asmbly Discipline Policy can be found [[Member Handbook#Discipline|HERE]]

Note: The people enforcing Asmbly policies are volunteers and it's not the most fun job. Failure to comply when approached about a policy violation is very serious. Show your fellow members kindness and respect when receiving redirection. Maintaining a cooperative community space at Asmbly is very important to us and ignoring the redirection of an appointed leader in the space is a serious violation.

Ceramics Policy

2025-10-29T23:05:23Z

EEatx: /* Mid-fire Glazes Currently in Studio for Members & Classes to use: */

[[Category:Ceramics]]

= Introduction =
Asmbly Policies outlined in the Member Handbook, [[Member Handbook#General%20Info|HERE]] apply to ALL shop areas including Ceramics. However Ceramics has some additional policies specific to the studio that are outlined below.

Check out the essential rules on How to Be Excellent, [[How to Be Excellent|HERE]]

Ceramics Safety & Information (CSI) is the required free class you must take before access to the studio with membership is granted. This is separate from the required Orientation & Facility Tour.

We are all caretakers of the shared space, so the cleanliness and maintenance is up to you!

= Usage Areas =
Refer the Equipment-Specific time limits [[Member Handbook#Equipment-specific%20time%20limits|HERE]]

==== Tools ====
You must reserve time for each tool you plan to use in Skedda. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Pottery Wheels: 8 machines available: Max booking is 5 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Wheel in Skedda up to 5 more hours
You must book yourself as a User if you plan on sitting at a Handbuilding Table, regardless of tool booking. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Handbuilding Tables: 8 Users can Book up to 5 hours of time between 4 tables (2 Users/table)
** It is not a specific table spot, just that you plan on using some table space
** When your time ends, check Skedda.
** If it is not booked you can rebook yourself as a User in Skedda up to 5 more hours
Use of the glazing area, slab roller, and extruder are included with booking of either a Pottery Wheel or Handbuilding Table. Please use these collaboratively, if multiple users need to utilize during the same time period. Be friendly and initiate conversations to best share access to these spaces.

NOTE: Glazes brought in must be labelled with the sharpie found at the Clay Store at Asmbly BEFORE being stored on your shelf!!

== Kiln Check-In Procedures ==
Currently Asmbly Makerspace is not limiting the number of pieces, or firings, you can participate in each month. We aim for a 1-2 week turnaround, but this could be longer or shorter depending on many factors. The Kiln Operators reserve the right to hold or delay a piece if it is not dry enough, or they feel the member needs to correct something to be safe to fire. The Kiln Operators will communicate with you when your piece is out of the Kiln, or before the firing if there are any issues. They can be reached at: [[Mailto:kilnops@asmbly.org|kilnops@asmbly.org]]

Firing Sign In Process

# Follow the QR Code to a Google Form for each type of firing
## Check in ALL your pieces with just one Google Form.
## Fill out ONE form for Bisque, and a NEW form for Glaze

2. Fill out one WHITE paper slip for EACH of your pieces

# This will serve as a physical record the Kiln Operators can track as things come in and out of the Kilns.

'''Example:''' You have 7 pieces: 4 for Bisque, and 3 for Glaze. You need to fill out 2 Google Forms (1 for each type of firing), and 7 white paper slips (1 to stay with each piece).

= Firing System =
We are aiming at Asmbly to have a turnaround of 1-2 weeks after you have placed your bone dry pieces on the shelf, to receive a fired piece. Dry pieces submitted to be fired will be put in the kilns on a first come, first in basis. There could be other factors, like not being dry enough, needing to prioritize a class, not enough pieces to fill a kiln, or other reasons that could potentially cause delays. All firing and kilns will be run by the Kiln Operators.

1. As of 4/22/2025 the Kilns will be fired to:

# Bisque Fired at Cone 04 (~1900-1940℉)
# Low-fire Glaze at Cone 04 (~1940℉)
# Mid-fire Glaze or Stoneware at Cone 6 (~2200℉).

2. Special temperature firings may occur at the discretion of the Lead Kiln Operator

3. ALL pieces must have wax resist on the bottom to avoid getting stuck to the shelves or supports

# If you want to put glaze all over and risk it getting stuck to the support, you must discuss this with the Lead Kiln Operators and be aware it may cause damage to your piece

3. We recommend you leave ¼”-½” around the base of your pieces to avoid sticking to the kiln shelves

# This is not required at this time, just strongly advised
# If serious issues arise it may be made an official policy
# The Kiln Operators reserve the right to ask you to make any corrections to your

==== Usage Violations ====

* Usage of unapproved clay & glazes will be recorded and not allowed
** It may result in damage to your or other’s pieces
** Kiln damage
* Repeated reported violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio

= Clay Body & Glaze Approval System =
Asmbly is a community of makers and creators, as such we want to honor the experimental nature that comes with clay and crafting. Ceramics has an endless amount of processes and abilities when it comes to glazing and firing, and we have created a system that strives to be fair and balanced to non-approved clay and glazes, while also maintaining the safety of member’s pieces and the Kilns at Asmbly.

# As of 4/22/2025 the Kilns will be fired to:
## Bisque Fired at Cone 04 (~1900-1940℉)
## Low-fire Glaze at Cone 04 (~1940℉)
## Mid-fire Glaze at Cone 6 (~2200℉).
# Clay or glazes that need a cooler or hotter maturation temperature will currently not be accepted.
## This could change in the future at the discretion of Asmbly
## Special projects may be considered
# Clay and glaze test pieces will be checked in the same way as other pieces, with the “Kiln Check In Form”, but will be placed on the Test Shelves
# We will not accept Glazes with Lead in any form in the studio
# The Skutt Kiln (Helios) is the test kiln
# Your piece may wait for some time, until we have a full load, and is fully dry before being fired

# This is up to the discretion of the Kiln Operators

Asmbly Makerspace is not responsible for any cracks that could occur before, during, or after the firing process.

It is rare, but if any damage to our kiln or kiln furniture is directly caused by your piece, you will be responsible for replacement or repair charges.

=== Clay Body ===
Non-Approved clay bodies must go through the following steps to be approved

# Bisque Fire:
## Please make a small piece out of your clay body, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
## Please allow it to dry, and then dry some more, before placing on the Greenware Test Shelf
### The longer you let it dry, the less time it will spend waiting to go in to the kiln
### We will not accept pieces that are still wet
# If it does not melt, crack excessively or otherwise seem dangerous it will be approved to be used along with our other approved clay bodies.

=== Glaze ===
Non-Approved glazes must go through the following steps to be approved

# Glaze Fire:
## Please make a small piece, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
#### If you do not have a piece to test your glaze on, a vertical test tile will be provided to you by Asmbly made of Cinco Blanco
## Glaze your piece with the glaze you are testing.
### Leave 1” of unglazed ceramic at the bottom to test if it runs or drips excessively
### Leave ¼” - ½” unglazed if using a provided vertical test tile
## Please apply the same glaze technique on the test piece you plan to apply on the actual piece, in order to get an accurate test.
### Same number of layers, colors, overlaps of glazes, etc.
# If it does not melt, crack excessively, craze past your liking, or otherwise seem dangerous it will be approved to be allowed in with the other glazes

= Discipline/Violations Policy =
Asmbly Discipline Policy can be found [[Member Handbook#Discipline|HERE]]

Note: The people enforcing Asmbly policies are volunteers and it's not the most fun job. Failure to comply when approached about a policy violation is very serious. Show your fellow members kindness and respect when receiving redirection. Maintaining a cooperative community space at Asmbly is very important to us and ignoring the redirection of an appointed leader in the space is a serious violation.

Ceramics Policy

2025-10-29T23:04:53Z

EEatx: /* Glazes Provided in Studio */ updated to remove unavailable glazes

[[Category:Ceramics]]

= Introduction =
Asmbly Policies outlined in the Member Handbook, [[Member Handbook#General%20Info|HERE]] apply to ALL shop areas including Ceramics. However Ceramics has some additional policies specific to the studio that are outlined below.

Check out the essential rules on How to Be Excellent, [[How to Be Excellent|HERE]]

Ceramics Safety & Information (CSI) is the required free class you must take before access to the studio with membership is granted. This is separate from the required Orientation & Facility Tour.

We are all caretakers of the shared space, so the cleanliness and maintenance is up to you!

= Usage Areas =
Refer the Equipment-Specific time limits [[Member Handbook#Equipment-specific%20time%20limits|HERE]]

==== Tools ====
You must reserve time for each tool you plan to use in Skedda. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Pottery Wheels: 8 machines available: Max booking is 5 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Wheel in Skedda up to 5 more hours
You must book yourself as a User if you plan on sitting at a Handbuilding Table, regardless of tool booking. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Handbuilding Tables: 8 Users can Book up to 5 hours of time between 4 tables (2 Users/table)
** It is not a specific table spot, just that you plan on using some table space
** When your time ends, check Skedda.
** If it is not booked you can rebook yourself as a User in Skedda up to 5 more hours
Use of the glazing area, slab roller, and extruder are included with booking of either a Pottery Wheel or Handbuilding Table. Please use these collaboratively, if multiple users need to utilize during the same time period. Be friendly and initiate conversations to best share access to these spaces.

==== Community Tools/Areas ====

** It is highly recommended you wear a mask while in the studio for prolonged and repetitive periods; especially while cleaning up!
** Use your own personal discretion
** NEVER make another person feel bad for wearing a mask.
* NEVER use a broom, WATER is the best way to safely clean up clay.
* If there is dry clay on the canvas topped tables, wet it with water to remove
** Do NOT scrape dry clay, it will kick up unnecessary dust

We are aiming at Asmbly to have a turnaround of 1-2 weeks after you have placed your bone dry pieces on the shelf, to receive a fired piece. Dry pieces submitted to be fired will be put in the kilns on a first come, first in basis. There could be other factors, like not being dry enough, needing to prioritize a class, not enough pieces to fill a kiln, or other reasons that could potentially cause delays. All firing and kilns will be run by the Kiln Operators.

1. As of 4/22/2025 the Kilns will be fired to:

# Bisque Fired at Cone 04 (~1900-1940℉)
# Low-fire Glaze at Cone 04 (~1940℉)
# Mid-fire Glaze or Stoneware at Cone 6 (~2200℉).

2. Special temperature firings may occur at the discretion of the Lead Kiln Operator

3. ALL pieces must have wax resist on the bottom to avoid getting stuck to the shelves or supports

# If you want to put glaze all over and risk it getting stuck to the support, you must discuss this with the Lead Kiln Operators and be aware it may cause damage to your piece

3. We recommend you leave ¼”-½” around the base of your pieces to avoid sticking to the kiln shelves

# This is not required at this time, just strongly advised
# If serious issues arise it may be made an official policy
# The Kiln Operators reserve the right to ask you to make any corrections to your

==== Usage Violations ====

* Usage of unapproved clay & glazes will be recorded and not allowed
** It may result in damage to your or other’s pieces
** Kiln damage
* Repeated reported violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio

= Clay Body & Glaze Approval System =
Asmbly is a community of makers and creators, as such we want to honor the experimental nature that comes with clay and crafting. Ceramics has an endless amount of processes and abilities when it comes to glazing and firing, and we have created a system that strives to be fair and balanced to non-approved clay and glazes, while also maintaining the safety of member’s pieces and the Kilns at Asmbly.

# As of 4/22/2025 the Kilns will be fired to:
## Bisque Fired at Cone 04 (~1900-1940℉)
## Low-fire Glaze at Cone 04 (~1940℉)
## Mid-fire Glaze at Cone 6 (~2200℉).
# Clay or glazes that need a cooler or hotter maturation temperature will currently not be accepted.
## This could change in the future at the discretion of Asmbly
## Special projects may be considered
# Clay and glaze test pieces will be checked in the same way as other pieces, with the “Kiln Check In Form”, but will be placed on the Test Shelves
# We will not accept Glazes with Lead in any form in the studio
# The Skutt Kiln (Helios) is the test kiln
# Your piece may wait for some time, until we have a full load, and is fully dry before being fired

# This is up to the discretion of the Kiln Operators

Asmbly Makerspace is not responsible for any cracks that could occur before, during, or after the firing process.

It is rare, but if any damage to our kiln or kiln furniture is directly caused by your piece, you will be responsible for replacement or repair charges.

=== Clay Body ===
Non-Approved clay bodies must go through the following steps to be approved

# Bisque Fire:
## Please make a small piece out of your clay body, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
## Please allow it to dry, and then dry some more, before placing on the Greenware Test Shelf
### The longer you let it dry, the less time it will spend waiting to go in to the kiln
### We will not accept pieces that are still wet
# If it does not melt, crack excessively or otherwise seem dangerous it will be approved to be used along with our other approved clay bodies.

=== Glaze ===
Non-Approved glazes must go through the following steps to be approved

# Glaze Fire:
## Please make a small piece, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
#### If you do not have a piece to test your glaze on, a vertical test tile will be provided to you by Asmbly made of Cinco Blanco
## Glaze your piece with the glaze you are testing.
### Leave 1” of unglazed ceramic at the bottom to test if it runs or drips excessively
### Leave ¼” - ½” unglazed if using a provided vertical test tile
## Please apply the same glaze technique on the test piece you plan to apply on the actual piece, in order to get an accurate test.
### Same number of layers, colors, overlaps of glazes, etc.
# If it does not melt, crack excessively, craze past your liking, or otherwise seem dangerous it will be approved to be allowed in with the other glazes

= Discipline/Violations Policy =
Asmbly Discipline Policy can be found [[Member Handbook#Discipline|HERE]]

Note: The people enforcing Asmbly policies are volunteers and it's not the most fun job. Failure to comply when approached about a policy violation is very serious. Show your fellow members kindness and respect when receiving redirection. Maintaining a cooperative community space at Asmbly is very important to us and ignoring the redirection of an appointed leader in the space is a serious violation.

EEatx: /* Mid-fire Glazes Currently in Studio for Members & Classes to use: */

[[Category:Ceramics]]

= Introduction =
Asmbly Policies outlined in the Member Handbook, [[Member Handbook#General%20Info|HERE]] apply to ALL shop areas including Ceramics. However Ceramics has some additional policies specific to the studio that are outlined below.

Check out the essential rules on How to Be Excellent, [[How to Be Excellent|HERE]]

Ceramics Safety & Information (CSI) is the required free class you must take before access to the studio with membership is granted. This is separate from the required Orientation & Facility Tour.

We are all caretakers of the shared space, so the cleanliness and maintenance is up to you!

= Usage Areas =
Refer the Equipment-Specific time limits [[Member Handbook#Equipment-specific%20time%20limits|HERE]]

==== Tools ====
You must reserve time for each tool you plan to use in Skedda. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Pottery Wheels: 8 machines available: Max booking is 5 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Wheel in Skedda up to 5 more hours
You must book yourself as a User if you plan on sitting at a Handbuilding Table, regardless of tool booking. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Handbuilding Tables: 8 Users can Book up to 5 hours of time between 4 tables (2 Users/table)
** It is not a specific table spot, just that you plan on using some table space
** When your time ends, check Skedda.
** If it is not booked you can rebook yourself as a User in Skedda up to 5 more hours
Use of the glazing area, slab roller, and extruder are included with booking of either a Pottery Wheel or Handbuilding Table. Please use these collaboratively, if multiple users need to utilize during the same time period. Be friendly and initiate conversations to best share access to these spaces.

==== Community Tools/Areas ====

* Please clean all tools you use from the communal tools and return to their storage location.
* Place brown paper on handbuilding tables if applying glaze
** Glaze should be kept from contaminating the canvas table surfaces

** It is highly recommended you wear a mask while in the studio for prolonged and repetitive periods; especially while cleaning up!
** Use your own personal discretion
** NEVER make another person feel bad for wearing a mask.
* NEVER use a broom, WATER is the best way to safely clean up clay.
* If there is dry clay on the canvas topped tables, wet it with water to remove
** Do NOT scrape dry clay, it will kick up unnecessary dust
* NO FOOD in the Studio, you risk eating glaze accidentally (Closed beverage containers OK)
* No sanding bisque pieces inside the studio.
* We have a Blue Ox Air filtration system installed in the studio to help cut back on particulates in the air.

== Kiln Check-In Procedures ==
Currently Asmbly Makerspace is not limiting the number of pieces, or firings, you can participate in each month. We aim for a 1-2 week turnaround, but this could be longer or shorter depending on many factors. The Kiln Operators reserve the right to hold or delay a piece if it is not dry enough, or they feel the member needs to correct something to be safe to fire. The Kiln Operators will communicate with you when your piece is out of the Kiln, or before the firing if there are any issues. They can be reached at: [[Mailto:kilnops@asmbly.org|kilnops@asmbly.org]]

Firing Sign In Process

# Follow the QR Code to a Google Form for each type of firing
## Check in ALL your pieces with just one Google Form.
## Fill out ONE form for Bisque, and a NEW form for Glaze

2. Fill out one WHITE paper slip for EACH of your pieces

# This will serve as a physical record the Kiln Operators can track as things come in and out of the Kilns.

'''Example:''' You have 7 pieces: 4 for Bisque, and 3 for Glaze. You need to fill out 2 Google Forms (1 for each type of firing), and 7 white paper slips (1 to stay with each piece).

= Firing System =
We are aiming at Asmbly to have a turnaround of 1-2 weeks after you have placed your bone dry pieces on the shelf, to receive a fired piece. Dry pieces submitted to be fired will be put in the kilns on a first come, first in basis. There could be other factors, like not being dry enough, needing to prioritize a class, not enough pieces to fill a kiln, or other reasons that could potentially cause delays. All firing and kilns will be run by the Kiln Operators.

1. As of 4/22/2025 the Kilns will be fired to:

# Bisque Fired at Cone 04 (~1900-1940℉)
# Low-fire Glaze at Cone 04 (~1940℉)
# Mid-fire Glaze or Stoneware at Cone 6 (~2200℉).

2. Special temperature firings may occur at the discretion of the Lead Kiln Operator

3. ALL pieces must have wax resist on the bottom to avoid getting stuck to the shelves or supports

# If you want to put glaze all over and risk it getting stuck to the support, you must discuss this with the Lead Kiln Operators and be aware it may cause damage to your piece

3. We recommend you leave ¼”-½” around the base of your pieces to avoid sticking to the kiln shelves

# This is not required at this time, just strongly advised
# If serious issues arise it may be made an official policy
# The Kiln Operators reserve the right to ask you to make any corrections to your

==== Usage Violations ====

* Usage of unapproved clay & glazes will be recorded and not allowed
** It may result in damage to your or other’s pieces
** Kiln damage
* Repeated reported violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio

= Clay Body & Glaze Approval System =
Asmbly is a community of makers and creators, as such we want to honor the experimental nature that comes with clay and crafting. Ceramics has an endless amount of processes and abilities when it comes to glazing and firing, and we have created a system that strives to be fair and balanced to non-approved clay and glazes, while also maintaining the safety of member’s pieces and the Kilns at Asmbly.

# As of 4/22/2025 the Kilns will be fired to:
## Bisque Fired at Cone 04 (~1900-1940℉)
## Low-fire Glaze at Cone 04 (~1940℉)
## Mid-fire Glaze at Cone 6 (~2200℉).
# Clay or glazes that need a cooler or hotter maturation temperature will currently not be accepted.
## This could change in the future at the discretion of Asmbly
## Special projects may be considered
# Clay and glaze test pieces will be checked in the same way as other pieces, with the “Kiln Check In Form”, but will be placed on the Test Shelves
# We will not accept Glazes with Lead in any form in the studio
# The Skutt Kiln (Helios) is the test kiln
# Your piece may wait for some time, until we have a full load, and is fully dry before being fired

# This is up to the discretion of the Kiln Operators

Asmbly Makerspace is not responsible for any cracks that could occur before, during, or after the firing process.

It is rare, but if any damage to our kiln or kiln furniture is directly caused by your piece, you will be responsible for replacement or repair charges.

=== Clay Body ===
Non-Approved clay bodies must go through the following steps to be approved

# Bisque Fire:
## Please make a small piece out of your clay body, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
## Please allow it to dry, and then dry some more, before placing on the Greenware Test Shelf
### The longer you let it dry, the less time it will spend waiting to go in to the kiln
### We will not accept pieces that are still wet
# If it does not melt, crack excessively or otherwise seem dangerous it will be approved to be used along with our other approved clay bodies.

## Glaze your piece with the glaze you are testing.
### Leave 1” of unglazed ceramic at the bottom to test if it runs or drips excessively
### Leave ¼” - ½” unglazed if using a provided vertical test tile
## Please apply the same glaze technique on the test piece you plan to apply on the actual piece, in order to get an accurate test.
### Same number of layers, colors, overlaps of glazes, etc.

Ceramics Policy

2025-10-29T21:26:04Z

EEatx: /* Mid-fire Glazes Currently in Studio for Members & Classes to use: */ removed Sky glaze

[[Category:Ceramics]]

= Introduction =
Asmbly Policies outlined in the Member Handbook, [[Member Handbook#General%20Info|HERE]] apply to ALL shop areas including Ceramics. However Ceramics has some additional policies specific to the studio that are outlined below.

Check out the essential rules on How to Be Excellent, [[How to Be Excellent|HERE]]

Ceramics Safety & Information (CSI) is the required free class you must take before access to the studio with membership is granted. This is separate from the required Orientation & Facility Tour.

We are all caretakers of the shared space, so the cleanliness and maintenance is up to you!

= Usage Areas =
Refer the Equipment-Specific time limits [[Member Handbook#Equipment-specific%20time%20limits|HERE]]

==== Tools ====
You must reserve time for each tool you plan to use in Skedda. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Pottery Wheels: 8 machines available: Max booking is 5 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Wheel in Skedda up to 5 more hours
You must book yourself as a User if you plan on sitting at a Handbuilding Table, regardless of tool booking. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Handbuilding Tables: 8 Users can Book up to 5 hours of time between 4 tables (2 Users/table)
** It is not a specific table spot, just that you plan on using some table space
** When your time ends, check Skedda.
** If it is not booked you can rebook yourself as a User in Skedda up to 5 more hours
Use of the glazing area, slab roller, and extruder are included with booking of either a Pottery Wheel or Handbuilding Table. Please use these collaboratively, if multiple users need to utilize during the same time period. Be friendly and initiate conversations to best share access to these spaces.

==== Community Tools/Areas ====

* Please clean all tools you use from the communal tools and return to their storage location.
* Place brown paper on handbuilding tables if applying glaze
** Glaze should be kept from contaminating the canvas table surfaces

** It is highly recommended you wear a mask while in the studio for prolonged and repetitive periods; especially while cleaning up!
** Use your own personal discretion
** NEVER make another person feel bad for wearing a mask.
* NEVER use a broom, WATER is the best way to safely clean up clay.
* If there is dry clay on the canvas topped tables, wet it with water to remove
** Do NOT scrape dry clay, it will kick up unnecessary dust
* NO FOOD in the Studio, you risk eating glaze accidentally (Closed beverage containers OK)
* No sanding bisque pieces inside the studio.
* We have a Blue Ox Air filtration system installed in the studio to help cut back on particulates in the air.

== Kiln Check-In Procedures ==
Currently Asmbly Makerspace is not limiting the number of pieces, or firings, you can participate in each month. We aim for a 1-2 week turnaround, but this could be longer or shorter depending on many factors. The Kiln Operators reserve the right to hold or delay a piece if it is not dry enough, or they feel the member needs to correct something to be safe to fire. The Kiln Operators will communicate with you when your piece is out of the Kiln, or before the firing if there are any issues. They can be reached at: [[Mailto:kilnops@asmbly.org|kilnops@asmbly.org]]

Firing Sign In Process

# Follow the QR Code to a Google Form for each type of firing
## Check in ALL your pieces with just one Google Form.
## Fill out ONE form for Bisque, and a NEW form for Glaze

2. Fill out one WHITE paper slip for EACH of your pieces

# This will serve as a physical record the Kiln Operators can track as things come in and out of the Kilns.

'''Example:''' You have 7 pieces: 4 for Bisque, and 3 for Glaze. You need to fill out 2 Google Forms (1 for each type of firing), and 7 white paper slips (1 to stay with each piece).

= Firing System =
We are aiming at Asmbly to have a turnaround of 1-2 weeks after you have placed your bone dry pieces on the shelf, to receive a fired piece. Dry pieces submitted to be fired will be put in the kilns on a first come, first in basis. There could be other factors, like not being dry enough, needing to prioritize a class, not enough pieces to fill a kiln, or other reasons that could potentially cause delays. All firing and kilns will be run by the Kiln Operators.

1. As of 4/22/2025 the Kilns will be fired to:

# Bisque Fired at Cone 04 (~1900-1940℉)
# Low-fire Glaze at Cone 04 (~1940℉)
# Mid-fire Glaze or Stoneware at Cone 6 (~2200℉).

2. Special temperature firings may occur at the discretion of the Lead Kiln Operator

3. ALL pieces must have wax resist on the bottom to avoid getting stuck to the shelves or supports

# If you want to put glaze all over and risk it getting stuck to the support, you must discuss this with the Lead Kiln Operators and be aware it may cause damage to your piece

3. We recommend you leave ¼”-½” around the base of your pieces to avoid sticking to the kiln shelves

# This is not required at this time, just strongly advised
# If serious issues arise it may be made an official policy
# The Kiln Operators reserve the right to ask you to make any corrections to your

==== Usage Violations ====

* Usage of unapproved clay & glazes will be recorded and not allowed
** It may result in damage to your or other’s pieces
** Kiln damage
* Repeated reported violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio

= Clay Body & Glaze Approval System =
Asmbly is a community of makers and creators, as such we want to honor the experimental nature that comes with clay and crafting. Ceramics has an endless amount of processes and abilities when it comes to glazing and firing, and we have created a system that strives to be fair and balanced to non-approved clay and glazes, while also maintaining the safety of member’s pieces and the Kilns at Asmbly.

# As of 4/22/2025 the Kilns will be fired to:
## Bisque Fired at Cone 04 (~1900-1940℉)
## Low-fire Glaze at Cone 04 (~1940℉)
## Mid-fire Glaze at Cone 6 (~2200℉).
# Clay or glazes that need a cooler or hotter maturation temperature will currently not be accepted.
## This could change in the future at the discretion of Asmbly
## Special projects may be considered
# Clay and glaze test pieces will be checked in the same way as other pieces, with the “Kiln Check In Form”, but will be placed on the Test Shelves
# We will not accept Glazes with Lead in any form in the studio
# The Skutt Kiln (Helios) is the test kiln
# Your piece may wait for some time, until we have a full load, and is fully dry before being fired

# This is up to the discretion of the Kiln Operators

Asmbly Makerspace is not responsible for any cracks that could occur before, during, or after the firing process.

It is rare, but if any damage to our kiln or kiln furniture is directly caused by your piece, you will be responsible for replacement or repair charges.

=== Clay Body ===
Non-Approved clay bodies must go through the following steps to be approved

# Bisque Fire:
## Please make a small piece out of your clay body, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
## Please allow it to dry, and then dry some more, before placing on the Greenware Test Shelf
### The longer you let it dry, the less time it will spend waiting to go in to the kiln
### We will not accept pieces that are still wet
# If it does not melt, crack excessively or otherwise seem dangerous it will be approved to be used along with our other approved clay bodies.

=== Glaze ===
Non-Approved glazes must go through the following steps to be approved

# Glaze Fire:
## Please make a small piece, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
#### If you do not have a piece to test your glaze on, a vertical test tile will be provided to you by Asmbly made of Cinco Blanco
## Glaze your piece with the glaze you are testing.
### Leave 1” of unglazed ceramic at the bottom to test if it runs or drips excessively
### Leave ¼” - ½” unglazed if using a provided vertical test tile
## Please apply the same glaze technique on the test piece you plan to apply on the actual piece, in order to get an accurate test.
### Same number of layers, colors, overlaps of glazes, etc.
# If it does not melt, crack excessively, craze past your liking, or otherwise seem dangerous it will be approved to be allowed in with the other glazes

How to Glaze

2025-09-29T23:27:08Z

EEatx: /* Before You Begin: */

== Before You Begin: ==

* Our glazing and cleaning procedures MUST be followed if you intend to use our communal products, glazing spaces, and kiln firing.
* DO NOT dip brushes directly into glaze jars--pour out glaze into provided bowls or cups,
* DO NOT return poured out glaze to glaze jars--these must remain uncontaminated, label remnant glaze in plastic cups
* DO NOT overglaze your piece--it will be rejected
* DO NOT use unapproved glazes (process listed below for approval of glazes)
* WAIT for each layer to fully dry before added another glazing
* DO use wax resist on the bottom of your piece, 1/4" if using one glaze, 1/2" if using multiple glazes and wipe off any glaze that dripped onto this area before loading it onto the kiln shelves

== Glazing: Step-by-Step ==
Below is a list of the procedures members need to make sure to follow, to guarantee a safe glazing process. Incorrect glazing may damage the member's own piece, other members' pieces inside a kiln, the kiln itself, and may even put at risk the safety of kiln operators and studio members.

Pieces that don't follow these instructions may be rejected by the kiln operators and placed in the "Rejected" shelf.
# '''Ensure your piece is bisque fired''' and free from dust BEFORE glazing (wipe gently with a damp sponge)
#'''Apply wax resist to the bottom''' of your piece using the small designated wax brushes provided
#*''Do not use your own brushes for wax resist''
#*'''Clean wax brushes''': Pick wax off into trash, then rinse in HOT water
#'''Stir your glaze thoroughly''' before use — glaze ingredients settle and must be evenly mixed
#'''Pour glaze into a small bowl''' before brushing. Do '''not dip brushes''' directly into the main glaze jars
#'''Apply glaze evenly'''
#* 1–3 coats depending on glaze type
#* Avoid over-applying to prevent drips and runs.
#* Reserve 1/2" of unglazed area at the bottom of your piece if:
#** thickly applied;
#** if it is a fast running type of glaze (fluxes, rutiles, are examples of fast running glazes. Read the manufacturers labels and they will let you know)
#** or if you are layering more than one type of glaze
# '''WAIT for each glaze layer to dry''' before applying again.
#'''Leave the bottom of the piece unglazed'''
#* Minimum 1/4" clearance (or 1" if for glaze testing)
#* Wipe foot completely clean to avoid kiln shelf damage
#'''Clean glaze brushes''': Rinse in the sink; use hand soap if needed — black glaze may require extra scrubbing
#'''Dry and return brushes to their designated containers'''
#'''Label your piece''' clearly if it's part of glaze testing
#'''Place on the Glaze Fire shelf''' and use check in form for kiln shelves
Please Note:
* Make sure your glaze is '''studio-approved or has passed testing'''
* '''Improper glazing or unlabeled pieces''' may be held back from firing and will be placed in the "rejected" shelf

== Glaze Testing & Approval Policy ==
To protect the integrity of our kilns, the safety of our members, and the quality of everyone’s work, we enforce a strict glaze approval policy. Only clearly defined and approved materials are permitted for use in the studio.
----

=== What Is Allowed ===
We only accept '''commercially manufactured glazes''', in the following forms:

* '''Pre-Mixed Commercial Glazes''' Liquid glazes sold ready-to-use by established ceramic glaze manufacturers (e.g., Amaco, Mayco, Laguna etc.).
* '''Studio-Approved Commercial Dry Glazes''' Powdered commercial dip glazes that are reconstituted '''under conditional supervision''' within the studio. These glazes must:
** Come directly from a commercial distributor
** Be mixed by or in coordination with designated studio personnel
** Receive prior approval from Seth or Perla
Please Note:

'''Members are not allowed to bring in, store, or mix dry commercial glaze powders on their own''', even if the materials are from reputable sources. All glaze mixing must be supervised and approved in advance.
----

=== What Is Not Allowed ===
The following are strictly '''prohibited''' in the studio:

* Any '''homemade''', '''member-formulated''', or '''DIY glaze recipes''', regardless of their source (e.g., books, online, ceramic blogs)
* Any mixture of raw glaze materials (oxides, frits, fluxes, etc.) sourced independently by members
* Any glaze materials or combinations that do '''not appear as a finished product in a commercial glaze bottle'''
* '''Mixing glaze powders''' outside the studio, including in outdoor common areas like the parking lot

To be clear: '''If it isn’t sold as a finished glaze product or mixed under the supervision of approved studio personnel, it is not allowed.'''
----

=== Mixing Policy ===

* '''No unsupervised mixing of glaze materials is allowed''', including reconstituting commercial dry dip glazes.
* Approved commercial dry glazes may be mixed only:
** Under the supervision of Seth, Perla, or another designated person
** In controlled and designated areas with proper PPE and ventilation
* Members are not permitted to bring in raw glaze materials or mix their own glazes in any studio or public area.

----

=== Glaze Testing ===

* All test firings must be approved and scheduled independently from regular kiln loads.
* A '''separate test kiln''' will be used when appropriate.
* The '''topmost studio shelves''' are designated for placing test pieces (bisque or glaze tests) and will be clearly labeled.

----

=== Approval & Communication ===
All materials not currently on the approved list must be reviewed and explicitly approved '''before''' use.

For approvals, contact:

* '''Seth White''' – seth.white@asmbly.org
* '''Perla Darnell''' – perla.darnell@asmbly.org

Email is the preferred and most reliable method of communication.
----

=== How to Test a Glaze ===

# '''Use a test piece''' (under 6" x 6" x 6") ''or'' request a vertical test tile from Asmbly (Cinco Blanco clay)
# '''Apply your glaze fully''' using the same number of coats, layering, and techniques you intend for your final work
#* Leave '''1" unglazed''' at the bottom of ceramic test pieces
#* Leave '''1/4"–1/2" unglazed''' on provided vertical test tiles
# '''Label''' the piece or tile with your name and the glaze name
# '''Place on the Glaze Test Shelf''' near the kilns
# '''Wait for glaze fire''' (scheduled based on kiln availability)
# '''Results will be assessed''' for running, crazing, blistering, or risk to kiln/kiln furniture

'''Please Note:'''

* You may lose the test piece
* Approved glazes will be added to our studio list.

== Approved Glazes at Asmbly ==
Asmbly is a community of makers, so we encourage exploration and creativity. Below are some of the glazes approved for use in our studio. This doesn't mean we carry them all, but it means you can use them. You will find all the available glazes in the glazing area. If the tube has a cookie test tile on top, it is one of the glazes we consistently restock; otherwise, it was a donation and can be used by anyone in the shop, but we don't carry it and repurchase it constantly.

If you are going to glaze a large piece with more layers than indicated by the instructions in the product, or if you plan to layer two different glazes, please use a test tile first to be sure it will not run and stick to the kiln.

Here is the list of pre-approved glazes:

==== Underglazes (Mayco Brand) ====

* '''Versatile & Food Safe''': Use for full coverage or in designs on clay, greenware, or bisque. Food safe when covered with a clear glaze.
* '''Firing Range''': Cone 6 - Cone 10 (We fire to cone 6).
* '''Application''': Shake well, apply 2-3 coats to wet clay or bisque, avoiding glaze pooling in textured areas.
* '''Firing''': Fire to cone 04, then apply clear glaze and fire to cone 06/05 for earthenware or cone 5-10 for stoneware.

----

==== Celadon Glazes (Amaco Brand) ====

* '''Translucent & Glossy Finish''': Ideal for highlighting texture on your pieces.
* '''Firing Range''': Cone 5 - Cone 6 (Food safe).
* '''Available at Asmbly''': Some colors available for members to use at no extra cost. Other colors can be brought in without testing.
* '''Application''': Follow the manufacturer’s instructions for number of coats. No need to mix with other glazes.

----

==== Potter's Choice Glazes (Amaco Brand) ====

* '''Fluid Colors & Effects''': Great for smooth or textured pieces. Not food safe.
* '''Firing Range''': Cone 5 - Cone 6.
* '''Available at Asmbly''': Some samples available, but members must purchase other colors.
* '''Application''': Test glazes first on a vertical test tile. If combining glazes, test on a tile before applying to pieces.
* '''Note''': Results can vary due to glaze interaction, especially when layering.

----

==== Satin Matte Glazes (Amaco Brand) ====

* '''Soft Satin Feel''': Semi-opaque glazes that break over texture and edges.
* '''Firing Range''': Cone 5 - Cone 6 (Food safe).
* '''Available at Asmbly''': Some colors in-house for free. Members can bring in other colors without testing.
* '''Application''': Follow the manufacturer’s instructions. No need to mix with other glazes.

----

==== Jungle Gems Glazes (Mayco Brand) ====

* '''Colorful & Textured''': Glass frit bursts create intricate patterns.
* '''Firing Range''': Cone 5 - Cone 6.
* '''Food Safety''': Not 100% food safe due to potential crazing.
* '''Available at Asmbly''': Some colors available for members to use, but members must purchase others.
* '''Application''': Shake well and apply 2-3 coats to bisque. Stir frequently, as crystals can settle. Avoid heavy application at the bottom of pieces to prevent glaze melting onto kiln shelves.
* '''Note''': The glass crystals bloom during firing, creating unique results each time.

== Summary ==

* Only studio-approved commercial glazes are permitted — '''no exceptions'''
* Dry commercial glazes may only be mixed '''under supervision''' — members cannot mix on their own or off-site
* '''No homemade recipes''', experimental blends, or member-sourced raw materials are allowed
* All glaze testing is separate from regular firings and must be placed on '''designated shelves'''
* Email '''Seth White (seth.white@asmbly.org)''' or '''Perla Darnell (perla.darnell@asmbly.org)''' for all material approval and testing coordination

EEatx: /* Tools */

[[Category:Ceramics]]

= Introduction =
Asmbly Policies outlined in the Member Handbook, [[Member Handbook#General%20Info|HERE]] apply to ALL shop areas including Ceramics. However Ceramics has some additional policies specific to the studio that are outlined below.

Check out the essential rules on How to Be Excellent, [[How to Be Excellent|HERE]]

Ceramics Safety & Information (CSI) is the required free class you must take before access to the studio with membership is granted. This is separate from the required Orientation & Facility Tour.

We are all caretakers of the shared space, so the cleanliness and maintenance is up to you!

= Usage Areas =
Refer the Equipment-Specific time limits [[Member Handbook#Equipment-specific%20time%20limits|HERE]]

==== Tools ====
You must reserve time for each tool you plan to use in Skedda. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Pottery Wheels: 8 machines available: Max booking is 5 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Wheel in Skedda up to 5 more hours
You must book yourself as a User if you plan on sitting at a Handbuilding Table, regardless of tool booking. It is your responsibility to CHECK SKEDDA to make sure the tool is not booked. Allow for clean up time within your booked time, NOT after. Members booked in Ceramics at the same time should work together to clean and coordinate space use.

* Handbuilding Tables: 8 Users can Book up to 5 hours of time between 4 tables (2 Users/table)
** It is not a specific table spot, just that you plan on using some table space
** When your time ends, check Skedda.
** If it is not booked you can rebook yourself as a User in Skedda up to 5 more hours
Use of the glazing area, slab roller, and extruder are included with booking of either a Pottery Wheel or Handbuilding Table. Please use these collaboratively, if multiple users need to utilize during the same time period. Be friendly and initiate conversations to best share access to these spaces.

==== Community Tools/Areas ====

* Please clean all tools you use from the communal tools and return to their storage location.
* Place brown paper on handbuilding tables if applying glaze
** Glaze should be kept from contaminating the canvas table surfaces

** It is highly recommended you wear a mask while in the studio for prolonged and repetitive periods; especially while cleaning up!
** Use your own personal discretion
** NEVER make another person feel bad for wearing a mask.
* NEVER use a broom, WATER is the best way to safely clean up clay.
* If there is dry clay on the canvas topped tables, wet it with water to remove
** Do NOT scrape dry clay, it will kick up unnecessary dust
* NO FOOD in the Studio, you risk eating glaze accidentally (Closed beverage containers OK)
* No sanding bisque pieces inside the studio.
* We have a Blue Ox Air filtration system installed in the studio to help cut back on particulates in the air.

NOTE: Glazes brought in must be labelled with the sharpie found at the Clay Store at Asmbly BEFORE being stored on your shelf!!

== Kiln Check-In Procedures ==
Currently Asmbly Makerspace is not limiting the number of pieces, or firings, you can participate in each month. We aim for a 1-2 week turnaround, but this could be longer or shorter depending on many factors. The Kiln Operators reserve the right to hold or delay a piece if it is not dry enough, or they feel the member needs to correct something to be safe to fire. The Kiln Operators will communicate with you when your piece is out of the Kiln, or before the firing if there are any issues. They can be reached at: [[Mailto:kilnops@asmbly.org|kilnops@asmbly.org]]

Firing Sign In Process

# Follow the QR Code to a Google Form for each type of firing
## Check in ALL your pieces with just one Google Form.
## Fill out ONE form for Bisque, and a NEW form for Glaze

2. Fill out one WHITE paper slip for EACH of your pieces

# This will serve as a physical record the Kiln Operators can track as things come in and out of the Kilns.

'''Example:''' You have 7 pieces: 4 for Bisque, and 3 for Glaze. You need to fill out 2 Google Forms (1 for each type of firing), and 7 white paper slips (1 to stay with each piece).

= Firing System =
We are aiming at Asmbly to have a turnaround of 1-2 weeks after you have placed your bone dry pieces on the shelf, to receive a fired piece. Dry pieces submitted to be fired will be put in the kilns on a first come, first in basis. There could be other factors, like not being dry enough, needing to prioritize a class, not enough pieces to fill a kiln, or other reasons that could potentially cause delays. All firing and kilns will be run by the Kiln Operators.

1. As of 4/22/2025 the Kilns will be fired to:

# Bisque Fired at Cone 04 (~1900-1940℉)
# Low-fire Glaze at Cone 04 (~1940℉)
# Mid-fire Glaze or Stoneware at Cone 6 (~2200℉).

2. Special temperature firings may occur at the discretion of the Lead Kiln Operator

3. ALL pieces must have wax resist on the bottom to avoid getting stuck to the shelves or supports

# If you want to put glaze all over and risk it getting stuck to the support, you must discuss this with the Lead Kiln Operators and be aware it may cause damage to your piece

3. We recommend you leave ¼”-½” around the base of your pieces to avoid sticking to the kiln shelves

# This is not required at this time, just strongly advised
# If serious issues arise it may be made an official policy
# The Kiln Operators reserve the right to ask you to make any corrections to your

==== Usage Violations ====

* Usage of unapproved clay & glazes will be recorded and not allowed
** It may result in damage to your or other’s pieces
** Kiln damage
* Repeated reported violations will result in not being allowed to put pieces in the kiln firings AND/OR prohibition from the studio

= Clay Body & Glaze Approval System =
Asmbly is a community of makers and creators, as such we want to honor the experimental nature that comes with clay and crafting. Ceramics has an endless amount of processes and abilities when it comes to glazing and firing, and we have created a system that strives to be fair and balanced to non-approved clay and glazes, while also maintaining the safety of member’s pieces and the Kilns at Asmbly.

# As of 4/22/2025 the Kilns will be fired to:
## Bisque Fired at Cone 04 (~1900-1940℉)
## Low-fire Glaze at Cone 04 (~1940℉)
## Mid-fire Glaze at Cone 6 (~2200℉).
# Clay or glazes that need a cooler or hotter maturation temperature will currently not be accepted.
## This could change in the future at the discretion of Asmbly
## Special projects may be considered
# Clay and glaze test pieces will be checked in the same way as other pieces, with the “Kiln Check In Form”, but will be placed on the Test Shelves
# We will not accept Glazes with Lead in any form in the studio
# The Skutt Kiln (Helios) is the test kiln
# Your piece may wait for some time, until we have a full load, and is fully dry before being fired

# This is up to the discretion of the Kiln Operators

Asmbly Makerspace is not responsible for any cracks that could occur before, during, or after the firing process.

It is rare, but if any damage to our kiln or kiln furniture is directly caused by your piece, you will be responsible for replacement or repair charges.

=== Clay Body ===
Non-Approved clay bodies must go through the following steps to be approved

# Bisque Fire:
## Please make a small piece out of your clay body, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
## Please allow it to dry, and then dry some more, before placing on the Greenware Test Shelf
### The longer you let it dry, the less time it will spend waiting to go in to the kiln
### We will not accept pieces that are still wet
# If it does not melt, crack excessively or otherwise seem dangerous it will be approved to be used along with our other approved clay bodies.

=== Glaze ===
Non-Approved glazes must go through the following steps to be approved

# Glaze Fire:
## Please make a small piece, such as a small mug, bowl, sculpture, etc.
### The piece should be no more than 6” x 6” x 6”
### Please be prepared to possibly lose this piece as it could crack or break in the test
#### If you do not have a piece to test your glaze on, a vertical test tile will be provided to you by Asmbly made of Cinco Blanco
## Glaze your piece with the glaze you are testing.
### Leave 1” of unglazed ceramic at the bottom to test if it runs or drips excessively
### Leave ¼” - ½” unglazed if using a provided vertical test tile
## Please apply the same glaze technique on the test piece you plan to apply on the actual piece, in order to get an accurate test.
### Same number of layers, colors, overlaps of glazes, etc.
# If it does not melt, crack excessively, craze past your liking, or otherwise seem dangerous it will be approved to be allowed in with the other glazes

= Discipline/Violations Policy =
Asmbly Discipline Policy can be found [[Member Handbook#Discipline|HERE]]

Note: The people enforcing Asmbly policies are volunteers and it's not the most fun job. Failure to comply when approached about a policy violation is very serious. Show your fellow members kindness and respect when receiving redirection. Maintaining a cooperative community space at Asmbly is very important to us and ignoring the redirection of an appointed leader in the space is a serious violation.
