Nona: /* Approved Glazes at Asmbly */

== 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 ==

# '''Ensure your piece is bisque fired''' and free from dust (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
# '''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

== 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.
----

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.'''

=== 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:

==== 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

=== 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.

----
=== 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 or Perla for all material approval and testing coordination.

How to Glaze

2025-06-16T00:12:16Z

Nona: Added a section that reiterates "How to test glazing"

'''Glaze Approval System'''

Glazes not already on our approved list must go through a testing process before use on any studio kilns.

'''Steps for Glaze Testing:'''

# '''Create a Test Piece:''' Make a small item no larger than 6" x 6" x 6" (e.g., mug, bowl, sculpture). If you do not have a piece, a vertical test tile made from Cinco Blanco will be provided by Asmbly.
# '''Apply Your Glaze:''' Glaze your piece or tile using the same technique, layering, color overlaps, and number of coats you intend to use on your final work. Leave at least 1" of unglazed ceramic at the bottom of a piece, or 1/4" to 1/2" if using a test tile.
# '''Label Clearly:''' Write your name and glaze name on the tile or piece.
# '''Submit to Glaze Test Shelf:''' Place on the designated Glaze Test shelf near the kilns.
# '''Wait for Firing:''' A glaze fire will be scheduled based on kiln availability.
# '''Assessment Criteria:''' Glazes will be assessed for running, pinholing, crazing, blistering, and any risk to kilns or others’ work.
# '''Approval or Feedback:''' If your glaze passes, it will be added to the approved list. Otherwise, you will receive feedback for adjustments.

Note: Be prepared to possibly lose your test piece in the process.

== Glaze Testing & Approval Policy ==

*Select larger electrode and increase amperage.
*Place stringer bead in proper location(s) at joint during welding.
*Adjust work angle or widen groove to access bottom during welding.
*Momentarily hold arc on groove side walls when using weaving technique.
*Keep arc on leading edge of weld puddle.
*Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before welding.
|-
|Lack of Penetration
|Shallow fusion between weld metal and base metal.
|
*Improper joint preparation.
*Improper weld technique.
*Insufficient heat input.
|
*Material too thick. Joint preparation and design must provide access to bottom of groove.
*Keep arc on leading edge of weld puddle.
*Increase amperage.
*Select larger electrode and increase amperage.
*Reduce travel speed.
|-
|Excessive Penetration
|Weld metal melts through the base metal and hangs underneath the weld.
|Excessive heat input.
|
*Select lower amperage.
*Use smaller electrode.
*Increase and/or maintain steady travel speed.
