How to Glaze

2025-12-12T21:17:35Z

Julirenner: /* Underglazes (Mayco Brand) */ changing cone 6 to cone 5, since we changed procedures

== 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 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

2025-12-12T21:15:02Z

Julirenner: /* Clays at Armadillo Clay Approved for Purchase */ eliminated info on prices, since we cannot guarantee prices at retailers, it will just make wiki look dated

[[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 =

** 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

= 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

== 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.

== 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.

Clay Recycling Program

2025-12-12T21:04:17Z

Julirenner: it is better that the discontinued program doesn't show up in the list of Ceramics/cathegory

== This program was discontinued in October 2025 due to lack of volunteer interest ==

== '''Overview''' ==
As long as it has not been fired, clay is infinitely recyclable! The ASMBLY clay recycling program is meant to help our space reclaim a material that can be easily reused rather than thrown into the landfill.

Members, students, and other participants are welcome to participate in the clay recycling program and add their scraps and slop to the communal buckets. We also encourage members to recycle their own clay as on a small scale, the process is easy and allows individual members to save money on purchasing new clay.

=='''Volunteering'''==
Volunteer tasks associated with clay recycling are part of the Ceramics Steward-On-Duty to-do list. Volunteers may not log separate hours for volunteer labor associated with this task.

== '''Bucket Guidelines''' ==

=== '''Dry Clay''' ===

* '''Best for:''' trimmings from wheel throwing or hand building, fully dried broken pieces
* Put clay scraps into the appropriate 5 gallon bucket
** The drier the better
** Only unfired clay (no glaze, no fired clay, no other contaminants)
** Absolutely no water - if your clay is wet, it does not go in this bucket

=== '''Slop''' ===

* '''Best for:''' slop from wheel throwing, slip from handbuilding
* Put clay slop into appropriate 5 gallon bucket
** When possible, strain out as much excess water as possible before adding your slop to this bucket - water will fill up these buckets fast!
** No glaze water or other contaminants

=== '''Locations''' ===

* Buckets have one location - between the wheel sink and the kiln drop off and pick up shelves (south wall of the studio)

=== '''Problems or Bucket Getting Full?''' ===
Notify us using the Problem Report ([https://docs.google.com/forms/d/e/1FAIpQLSfBhIcxwJPpBbuTVlxZ6-hSfNduEM5kkT0e4JP_uxGe9Ar75Q/viewform asmbly.org/problem]) when the buckets are ¾ or more full.

== '''Recycling Steps''' ==

=== '''Member and Teacher Responsibility''' ===

* Add dry clay scraps and slop to the appropriate buckets
* Notify Winnie with a Problem Report when the buckets are ¾ or more full

=== '''Volunteer Responsibility''' ===

==== '''Make the Mix''' ====

* '''Dry Clay:''' If clay scraps are not fully dried out, dry out in the sun until fully dry (crumbly/brittle)
* '''Slop:''' Strain clay slop and mix with fully dried scraps, add water as needed
* '''Initial Mix:''' Make sure everything gets submerged
* '''Wait:''' Let sit for 24 hours or longer

==== '''Dry It Out''' ====

* '''Mix Again:''' Hand mix or use heavy duty paint mixer to homogenize the newly mixed scraps and slop (should be very wet clay texture)
* '''Dry:''' Spread out onto Hardibacker sheets
** If left outside (especially if out in the sun), check every 1-2 hours until pliable
** If left inside, check every 12-24 hours until pliable

==== '''Prep It For Use''' ====

* '''Slam Wedge:''' Slam wedge together to homogenize mix
* '''Wedge:''' Cut into smaller chunks and spiral or ramshead wedge until there are no bubbles
* '''Bag:''' Bag up into old 20lb bags, secure tightly

== '''Recycled Clay Usage''' ==
Recycling clay is a very labor intensive process, if you volunteer to help with the process you will get first dibs on the free recycled clay. Remaining Recycled Clay will be used for classes, CSIs, events, special firings, SIGs, and other community oriented Asmbly activities.

Clay - Asmbly Approved

2025-12-12T20:40:59Z

Julirenner: /* 1. Approved Clay bodies */

=== 1. Approved Clay bodies ===
Our current approved clay bodies are the following mid-fire (cones 5/6)commercial clays that can be purchased at Armadillo Clay:

* Buffalo Wallow
* Cinco Blanco
* Buffalo Wallow with grog
* Cinco Rojo
* Cinco Rojo with grog
* Cone 5 Porcelain
* Laguna B-Mix cone 5
* Laguna B-Mix cone 5 with speckles
* Laguna Speckled Buff
* Laguna Azabache
* Laguna B-3 Brown
* Dark Chocolate no.32 Cone 5/6

Of these approved bodies, two of them can be purchased inside our Ceramics shop:
* Buffalo Wallow - supplier Armadillo Clay
* Cinco Blanco - supplier Armadillo Clay

We will gradually increase the amount of clays we allow users to fire at ASMBLY, but they all must be mid-fire clay bodies (cone 5/6), bisqued at cone 04, because this is the temperature we are currently bisquing in our kilns AND it is the temperature recommended for bisque pieces by most commercial glazes and dips.

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.

To align with that spirit, we have a Clay Body & Glaze Approval System.

=== 2. Our Clay Body & Glaze Approval System: ===
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.
## If you desire to use you own glaze you must follow the glaze approval system (see Approved Glazes and Glaze Approval System).

Clay trap - how to clean it

2025-10-13T18:47:03Z

Julirenner:

Clay traps are located underneath each of the sinks at the Ceramics shop. They must be cleaned once a month, or whenever the little see-through window looks completely dark. Here is a step by step on how to do it:[[File:Plastic bags refill for clay trap.jpg|alt=Plastic bag refill for clay traps at ASMBLY Ceramics studio|thumb|Plastic bag refill for clay traps at ASMBLY Ceramics studio]]

1) Find the plastic strong bags marked Clay traps in the storage room (either Kiln shelf or Shop Consumables)

2) Underneath the sink, find the clay traps and unscrew the 4 butterfly screws. Get rid of excess of water before trying to lift the bucket or take bag out of the bucket, because it may overflow and it will become to heavy and hard to close;
[[File:Clay trap underneath sink.jpg|alt=Clay trap underneath the sinks at the Ceramics Studio|thumb|Clay trap underneath the sinks at the Ceramics Studio]]

3) Take bag of remaining slush and tie it down;

Glaze Mixing Program

2025-09-15T23:42:54Z

Julirenner: /* 1) Start with a vetted “core set” of glazes */

[[Category:Ceramics]]

== Purpose ==
Our glaze program exists to give members safe, reliable, and affordable finishing options while protecting the makerspace from unnecessary risk. Instead of relying on retail, brush-on products with variable ingredient transparency and high per-ounce costs, we formulate and mix studio dip glazes in controlled batches. This approach supports our community mission in five ways:

* Cost stewardship (do more with our budget). Raw glaze materials (clays, fluxes, colorants) purchased in bulk reduce the per-gallon cost of glaze to a fraction of comparable commercial products. Lower unit costs mean we can keep member fees reasonable, keep buckets filled, and allocate more of the ceramics budget to essentials (kiln maintenance, shelves, furniture, tools).
* Ingredient transparency & food-contact accountability. By owning the recipe, we know exactly which oxides are present and at what levels. That lets us:
** avoid or tightly control restricted/toxicants in food-contact glazes,
** label glazes clearly for intended use (e.g., “liner,” “decorative only”) with certainty.
* Consistency and quality control. In-house batching allows us to standardize mixing steps (weighing, sieving, deflocculation/flocculation), target specific gravity/viscosity, and test each batch on reference tiles before release. Members get predictable results across firings because the glaze in the bucket is the same each time.
* Risk management and liability reduction. Centralized control over formulas, labeling, and process minimizes hazards that arise when unknown or altered commercial products are brought into a shared studio. Documented recipes, batch logs, and test tiles provide traceability if an issue arises (e.g., kiln damage, unexpected surface defects, or food-safety concerns).
* Education and community benefit. Our program teaches best practices—safe material handling, glaze chemistry basics, and process discipline—while providing a dependable, shared resource. Members learn why variables like thickness, clay body, and firing schedule matter, and they can make informed, creative choices within safe parameters.

In short, mixing our own glazes gives Asmbly control over costs, safety, and consistency, ensuring members have access to dependable finishes without compromising health, equipment, or budgets.

== Method ==
Our glaze program uses a phased, demand-driven approach managed by trained stewards. This ensures safety, consistency, and sustainable use of volunteer time and budget.

=== 1) Start with a vetted “core set” of glazes ===

* What we do: The ceramics lead and glaze stewards select an initial batch of widely useful, studio-safe dip glazes that fit our clay bodies and firing schedule.
* Why we do it: Beginning with a proven set limits variables during launch. It lets us refine mixing, labeling, testing, and firing workflows before expanding options—reducing waste, surprises, and kiln risk.

=== 2) Expand recipes based on member demand and safety ===

* What we do: Additional glazes may be added when there is clear member demand and the recipe is safe to produce (no restricted materials for food-contact, stable at our cone, compatible with our kilns and shelves). Requests are gathered via the ceramics volunteers Slack channel and at steward on duty sessions. Candidate recipes are small-batch tested before adoption.
* Why we do it: New glazes consume chemicals, studio space, kiln space and firing time, as well as volunteer labor. Requiring broad interest and a safety review keeps the lineup useful, affordable, and low-risk for a shared studio.

=== 3) Experienced stewards mix batches at launch ===

* What we do: Only the glaze stewards designated for the program perform mixing initially. They handle weighing, wetting-out, sieving, setting specific gravity/viscosity, and producing labeled test tiles for approval before a bucket is released to members.
* Why we do it: Mixing involves chemical handling, equipment care, and quality control. Centralizing early batches with experienced stewards builds consistent procedures and a reliable baseline.

=== 4) Train additional stewards through a structured shadow-to-sign-off path ===

* What we do: Volunteers interested in learning glaze mixing monitor the ceramics volunteers Slack channel for posted opportunities to assist. Training follows a progression:
*# Observe a full batch (PPE, dust control, weighing, sieving, cleanup).
*# Assist under supervision (measure, sieve, record batch data).
*# Lead a batch with a mentor present.
*# Sign-off to mix approved recipes independently.
* Why we do it: A clear ladder preserves safety and quality while growing program capacity. It also documents who is competent to handle chemicals and make decisions during mixing.

=== 5) Use a repeatable mixing & QA workflow ===

* What we do (each batch):
** Pre-check: Confirm approved recipe and inventory of materials.
** Weigh & mix: Measure by mass on calibrated scales; wet-blend to minimize airborne dust.
** Sieve: Pass to the specified mesh to remove agglomerates and improve application.
** Adjust: Set specific gravity/viscosity to target; record numbers on the batch log.
** Test tiles: Apply to standard clay bodies at standard thicknesses; fire on the studio schedule.
** Review & release: When test results match reference (surface, fit, food-contact designation), label the bucket (cone, use, batch ID, SG/viscosity, date) and place it in service.
* Why we do it: Consistency depends on accurate measurement, particle size control, and repeatable rheology. Test tiles and logs create traceability and help diagnose issues quickly.

=== 6) Manage inventory and scheduling ===

* What we do: Stewards maintain an inventory sheet with target par levels for each glaze. When a bucket reaches the reorder line, a mixing session is scheduled and posted in Slack (inviting trainees if appropriate).
* Why we do it: Proactive scheduling prevents stockouts, aligns volunteer availability with studio needs, and creates predictable learning opportunities.

=== 7) Document everything ===

* What we do: Keep a batch log (recipe version, mixer, dates, SG/viscosity, sieving notes, test-tile photos, kiln program used, and any anomalies). Changes to a recipe or process are recorded as a new version and announced in Slack.
* Why we do it: Documentation underpins safety, quality, and liability control. If a defect or kiln incident occurs, we can trace causes and fix them without guesswork.

----In short: experienced stewards launch and stabilize the core glazes; new glazes are added only when safe and broadly useful; volunteers grow into mixing roles through supervised practice and documented sign-off; and every batch follows the same measured, test-verified workflow for consistent, studio-safe results.

== Safety ==
Glaze mixing is the highest-risk activity in ceramics because it concentrates three hazards at once:

* Respirable dust from finely milled powders (silica, alumina, feldspathic materials) that can lodge deep in the lungs.
* Toxic metal oxides and carbonates (e.g., copper, cobalt, manganese, barium, chrome in some recipes) that pose inhalation and ingestion risks.
* Process intensity (pouring, weighing, sieving) that easily disperses powders into the air and onto surfaces.

Our safety rules are designed to control those risks at the source, protect people nearby, and prevent contamination of the studio.
----

== Who may mix ==
Only approved glaze stewards may handle dry glaze materials or mix batches.

Why: Trained stewards follow established controls (correct PPE, wet-mixing technique, batch logs) that minimize airborne dust and exposure for everyone in the makerspace.
----

== Where mixing happens ==
All dry-material handling and mixing occur outdoors in a designated area posted in Slack before each session.

Why: Outdoor air dilution greatly reduces airborne concentration of fine particulates. It also keeps any incidental dust out of the studio and kilns, where it could contaminate surfaces and ware.

Set-up requirements

* Work upwind of bystanders; post cones/tape a 10–15 ft buffer around the mixing table.
* Use a stable, wipeable surface (plastic-covered table or dedicated cart).
* Keep water on hand for wet-methods and immediate cleanup.

----

== Required PPE ==
For mixers and helpers (mandatory):

* Respiratory protection: NIOSH-approved P100 (elastomeric half-face with P100 cartridges or P100 disposable) for any dry-material handling.
** Perform a user seal check each time. Facial hair that breaks the seal is not compatible with a tight-fitting respirator.
* Gloves: Nitrile or equivalent, changed when soiled.
* Eye protection: Safety glasses; use a face shield during vigorous sieving or when splashing is likely.
* Footwear: Closed-toe, non-mesh shoes.

== Clothing / outer layer (strongly encouraged, see heat note): ==

* Long sleeves or a shed-able outer layer (lab coat, work shirt, Tyvek). Why: Sleeves reduce skin contamination and make it easy to remove dust before re-entering the building. In Texas heat, the outer layer is optional for comfort, but it remains the best practice.

----

== Handling practices (how we keep dust down) ==

* Add powder to water—never water to powder. Why: Wetting particles as they enter the bucket minimizes airborne dust.
* Pour low and slow; scoop instead of dumping. Why: Short drop distances and controlled flow prevent plumes.
* Keep lids closed on bags and buckets when not in active use. Why: Limits incidental dispersal by wind.
* Sieve wet, not dry. Why: Wet sieving removes agglomerates without aerosolizing particles.
* Measure by mass on calibrated scales. Why: Accuracy prevents rework and extra handling time (less exposure overall).
* No food, drink, or touching your face during mixing. Why: Prevents ingestion pathways.

----

== Cleanup (what’s allowed and what isn’t) ==

* Wet wipe surfaces and tools; do not dry sweep or use compressed air. Why: Wet methods trap dust; sweeping and air hoses re-suspend it.
* Collect slurry rinse water in a settling bucket; follow the studio’s waste protocol for decanting and disposing of settled solids. Never pour concentrated slurry down drains. Why: Protects plumbing, traps heavy solids, and keeps metals out of wastewater.
* Place soiled wipes and disposable sheeting in a sealed trash bag.

----

== Re-entry to the studio (clothing & decontamination) ==

* Brush-off is not enough. If you did not wear a shed-able outer layer, do not linger in the studio after mixing. Why: Dust on clothing migrates to shared benches, wheels, and ware.
* If your outer layer shows visible dust, bag it outside and launder it separately; do not bring it into the building. Why: Prevents cross-contamination of the indoor environment.
* Handwashing with soap and water is required before touching studio equipment.

----

== Prohibited practices ==

* Mixing or handling dry materials indoors.
* Dry sweeping, compressed air, or leaf blowers for cleanup.
* Open-toed shoes or mesh footwear.
* Allowing untrained members, children, or pets inside the buffer zone.
* Bringing unvetted, unlabeled powders for studio use.

Why: Each of the above either increases exposure risk, contaminates the studio, or undermines traceability.
----

== Health monitoring & incident response ==

* If you experience coughing, throat irritation, dizziness, or eye irritation during mixing, step away upwind immediately and inform the steward lead.
* For splashes to eyes/skin, flush with water for 15 minutes and report the incident.
* Report any spill, PPE failure, or near-miss so we can improve procedures.

----

== Why this matters for everyone—mixers and non-mixers alike ==
Controlling dust at the source protects:

* People: reduces risk of respiratory disease and metal exposures.
* Equipment: keeps kilns, shelves, and wheels free of contaminant films that can damage ware and elements.
* Community trust: members can work confidently knowing glaze mixing is tightly managed.

Bottom line: Glaze mixing is restricted, conducted outdoors, and done under strict PPE and cleanup protocols because that’s what it takes to keep a shared studio safe, clean, and healthy.

* What we do: Keep a batch log (recipe version, mixer, dates, SG/viscosity, sieving notes, test-tile photos, kiln program used, and any anomalies). Changes to a recipe or process are recorded as a new version and announced in Slack.
* Why we do it: Documentation underpins safety, quality, and liability control. If a defect or kiln incident occurs, we can trace causes and fix them without guesswork.

----In short: experienced stewards launch and stabilize the core glazes; new glazes are added only when safe and broadly useful; volunteers grow into mixing roles through supervised practice and documented sign-off; and every batch follows the same measured, test-verified workflow for consistent, studio-safe results.

=== Safety ===
Glaze mixing is the highest-risk activity in ceramics because it concentrates three hazards at once:

* Respirable dust from finely milled powders (silica, alumina, feldspathic materials) that can lodge deep in the lungs.
* Toxic metal oxides and carbonates (e.g., copper, cobalt, manganese, barium, chrome in some recipes) that pose inhalation and ingestion risks.
* Process intensity (pouring, weighing, sieving) that easily disperses powders into the air and onto surfaces.

Our safety rules are designed to control those risks at the source, protect people nearby, and prevent contamination of the studio.
----

== Who may mix ==
Only approved glaze stewards may handle dry glaze materials or mix batches.

Why: Trained stewards follow established controls (correct PPE, wet-mixing technique, batch logs) that minimize airborne dust and exposure for everyone in the makerspace.
----

== Where mixing happens ==
All dry-material handling and mixing occur outdoors in a designated area posted in Slack before each session.

Why: Outdoor air dilution greatly reduces airborne concentration of fine particulates. It also keeps any incidental dust out of the studio and kilns, where it could contaminate surfaces and ware.

Set-up requirements

* Work upwind of bystanders; post cones/tape a 10–15 ft buffer around the mixing table.
* Use a stable, wipeable surface (plastic-covered table or dedicated cart).
* Keep water on hand for wet-methods and immediate cleanup.

----

== Required PPE ==
For mixers and helpers (mandatory):

* Respiratory protection: NIOSH-approved P100 (elastomeric half-face with P100 cartridges or P100 disposable) for any dry-material handling.
** Perform a user seal check each time. Facial hair that breaks the seal is not compatible with a tight-fitting respirator.
* Gloves: Nitrile or equivalent, changed when soiled.
* Eye protection: Safety glasses; use a face shield during vigorous sieving or when splashing is likely.
* Footwear: Closed-toe, non-mesh shoes.

== Clothing / outer layer (strongly encouraged, see heat note): ==

* Long sleeves or a shed-able outer layer (lab coat, work shirt, Tyvek). Why: Sleeves reduce skin contamination and make it easy to remove dust before re-entering the building. In Texas heat, the outer layer is optional for comfort, but it remains the best practice.

----

== Handling practices (how we keep dust down) ==

* Add powder to water—never water to powder. Why: Wetting particles as they enter the bucket minimizes airborne dust.
* Pour low and slow; scoop instead of dumping. Why: Short drop distances and controlled flow prevent plumes.
* Keep lids closed on bags and buckets when not in active use. Why: Limits incidental dispersal by wind.
* Sieve wet, not dry. Why: Wet sieving removes agglomerates without aerosolizing particles.
* Measure by mass on calibrated scales. Why: Accuracy prevents rework and extra handling time (less exposure overall).
* No food, drink, or touching your face during mixing. Why: Prevents ingestion pathways.

----

== Cleanup (what’s allowed and what isn’t) ==

* Wet wipe surfaces and tools; do not dry sweep or use compressed air. Why: Wet methods trap dust; sweeping and air hoses re-suspend it.
* Collect slurry rinse water in a settling bucket; follow the studio’s waste protocol for decanting and disposing of settled solids. Never pour concentrated slurry down drains. Why: Protects plumbing, traps heavy solids, and keeps metals out of wastewater.
* Place soiled wipes and disposable sheeting in a sealed trash bag.

----

== Re-entry to the studio (clothing & decontamination) ==

* Brush-off is not enough. If you did not wear a shed-able outer layer, do not linger in the studio after mixing. Why: Dust on clothing migrates to shared benches, wheels, and ware.
* If your outer layer shows visible dust, bag it outside and launder it separately; do not bring it into the building. Why: Prevents cross-contamination of the indoor environment.
* Handwashing with soap and water is required before touching studio equipment.

----

== Prohibited practices ==

* Mixing or handling dry materials indoors.
* Dry sweeping, compressed air, or leaf blowers for cleanup.
* Open-toed shoes or mesh footwear.
* Allowing untrained members, children, or pets inside the buffer zone.
* Bringing unvetted, unlabeled powders for studio use.

Why: Each of the above either increases exposure risk, contaminates the studio, or undermines traceability.
----

== Health monitoring & incident response ==

* If you experience coughing, throat irritation, dizziness, or eye irritation during mixing, step away upwind immediately and inform the steward lead.
* For splashes to eyes/skin, flush with water for 15 minutes and report the incident.
* Report any spill, PPE failure, or near-miss so we can improve procedures.

----

== Why this matters for everyone—mixers and non-mixers alike ==
Controlling dust at the source protects:

* People: reduces risk of respiratory disease and metal exposures.
* Equipment: keeps kilns, shelves, and wheels free of contaminant films that can damage ware and elements.
* Community trust: members can work confidently knowing glaze mixing is tightly managed.

Bottom line: Glaze mixing is restricted, conducted outdoors, and done under strict PPE and cleanup protocols because that’s what it takes to keep a shared studio safe, clean, and healthy.

Music & Noise Policy

2025-09-15T19:23:57Z

Julirenner: inserted the new music & noise policy

[[Category:Policies]]

'''Music & Noise Policy'''

Our studio is a shared creative environment where both inspiration and focus matter. This policy ensures that everyone can enjoy the space respectfully, whether they thrive in silence or with background music.

'''Music & Shared Speaker'''

* Ask first before connecting to the studio speaker. Rotate music control if multiple members are present and interested in using the shared speaker.
* No explicit music in the shared space. Choose music that is broadly “studio friendly”—avoid harsh, explicit, or jarring tracks.
* Moderate volume – if someone asks to turn it down, please do. Volume should stay low enough to chat comfortably without raising your voice.
* Classes always take priority for speaker use. Class instructors control the music and sound environment. If you are a general member during a class, please keep personal noise minimal.

'''Phone Usage'''

* Keep phone conversations brief and at a low volume. Step outside for longer or more personal calls.
* No loud phone calls or video calls in the shared studio space.
* Speakerphone use is not allowed.
* Do not play music, videos, or other audio through your phone speakers—use headphones instead.

'''Respect & Courtesy'''

* Show respect toward all instructors, CSI leads, and volunteers at all times.
* Follow directions when asked to adjust noise levels, music, or phone use.
* Members may be reminded of these policies by instructors, staff, or volunteers.
* Continued failure to adhere to the policy may result in disciplinary measures, including loss of shared speaker privileges or other studio access restrictions.

How to Glaze

2025-09-15T18:32:48Z

Julirenner:

== Before You Begin: ==

* '''Book the Glaze Area on Skedda''' before using. Max 5 hours per session. All tool use counts toward your weekly 25-hour limit.

== 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
#'''Label your piece''' clearly if it's part of glaze testing
#'''Place on the Glaze Fire shelf''' for kiln loading
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).

* '''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'''

Ceramics Policy

2025-08-27T17:52:22Z

Julirenner: updated the Safety area to include current status of Blue Ox filtration, how to use it, and info about sanding

[[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: 5 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
* Extruder: 1 tool available: Comes with the extruder table next to it, max booking is 3 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Extruder in Skedda up to 3 more hours
* Slab Roller: 1 tool available: Max booking is 3 hours of time
** When your time ends, check Skedda.
** If it is not booked you can rebook the Slab Roller in Skedda up to 3 more hours
** NOTE: If you are making a lot of slabs, it is recommended you Book a Table with the note, “Using Slab Roller” as a User in the studio to give you somewhere besides your shelf to put the slabs.

==== Studio User ====
You must book yourself as a User if you plan on sitting at a Handbuilding Table, regardless of tool booking. You must also reserve time for each tool you plan to use on Skedda (see above). 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 2 tables (4 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
* Glaze Area: 2 Users can Book up to 5 hours at a time in the Glaze area
** NOTE: If you are glazing a large amount of items, please book a User table space in addition to the glaze area and put a note on the Table booking you will be, “Using Table for Glazing”, and on the Glaze booking that you will be, “Using a table”
** When your time ends, check Skedda.
** If it is not booked you can rebook the Table in Skedda up to 5 more hours

==== 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.
** If you are a staff or a volunteer, and you absolutely need to turn the filtration system off, please make sure to 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 ===
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.

Clay - Asmbly Approved

2025-06-04T16:38:54Z

Julirenner: added approved clays and new clays approval process

=== 1. Approved Clay bodies ===
Our current fully approved clay bodies are:

* Buffalo Wallow - supplier Armadillo Clay
* Cinco Blanco - supplier Armadillo Clay

The fully approved clay bodies can be purchased inside our Ceramics shop at the same price you would purchase them at Armadillo Clay.

We will gradually increase the amount of clays we allow users to fire at ASMBLY, but they all must be mid-fire clay bodies,bisqued at cone 04, because this is the temperature we are currently bisquing in our kilns AND it is the temperature recommended for bisque pieces by most commercial glazes and dips.

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.

To align with that spirit, we have a Clay Body & Glaze Approval System.

=== 2. Our Clay Body & Glaze Approval System: ===
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.
## If you desire to use you own glaze you must follow the glaze approval system (see Approved Glazes and Glaze Approval System).
