A practical guide for working studios
Ceramic glaze guide for artists and studios
Fired results depend on your clay body, application thickness, combinations, firing process, and temperature. Use the collection notes to compare options for independent artists, pottery studios, and ceramic businesses, then test on the body and kiln you use.
Glossy finish
Bright
Transparent glossy glazes for intense color and a clear surface. Supplier guidance lists 1180–1280 °C / Cone 4–9. Bright can be explored with Matt for a satin look and with Vibes for a reactive effect.
Matte finish
Matt
Matt glazes give a more restrained finish that keeps attention on the ceramic form. The supplier notes list 1180–1280 °C / Cone 4–9 and describe satin results when combined with Bright.
Translucent finish
Celadon
Translucent glossy surfaces show more variation where glaze pools in texture or carving. Supplier guidance lists 1180–1280 °C / Cone 4–9 and suggests exploring Matt and Vibes combinations.
Reactive effect
Vibes
Vibes is a reactive glossy effect glaze listed at 1000–1280 °C / Cone 06–9. It can act as a top or base layer; effects become more pronounced at higher temperatures and the supplier notes that it can run.
Crystalline effect
Crystal
Crystal glazes form crystals during firing. Supplier information lists a standard 1220 °C / Cone 6 firing with a 20-minute soak and recommends a glaze catcher because the glaze can run.
Reactive stoneware
By The Sea
By The Sea is a reactive stoneware collection with a coastal, tactile direction. Most colors are listed at 1180–1280 °C / Cone 4–9; K005 Pale Tide, K013 Dusky Reef, K014 Ocean Sunset, K022 Dark & Stormy and K025 Night Reef are listed at about 1140–1240 °C / Cone 2–6. Check the item page and make a test tile first.
Application notes
Build a repeatable glaze test.
- Stir the glaze well before application.
- Brush, sponge, or stamp according to the surface you want to build.
- Apply two or three coats as a starting point, allowing each coat to dry before the next.
- Record clay body, coat count, firing schedule, and any combination on your test tile.
What affects the fired result?
Clay body, glaze thickness, glaze combinations, firing process, peak temperature, and cooling can all change the fired surface. A supplier swatch is a reference point; results can differ with the clay body, application, and kiln.
Crystal note: supplier guidance includes a detailed Cone 7 schedule as well as a simplified 1220 °C / 20-minute soak option. Use a kiln-safe test setup and glaze catcher when appropriate.
Frequently asked questions
Answers before you fire.
Use these answers as planning starting points. The item guidance takes priority, and a labeled test tile on your own clay body is the best comparison before production.
How many coats should I apply?
Start with two or three even coats. Stir the glaze thoroughly before use so settled material is mixed back in, and let each coat dry before applying the next. Brush, sponge, or stamp according to the surface you want to build.
One person’s “coat” can be thicker than another’s, so make two labeled test tiles with different coat counts. That gives you a practical comparison for color depth, coverage, texture, and movement in your kiln.
What firing range should I use?
Begin with the guidance for the specific item rather than assuming every collection shares one schedule. Bright, Matt, and Celadon are listed at 1180–1280 °C / Cone 4–9. Vibes is listed at 1000–1280 °C / Cone 06–9. Crystal is listed at 1180–1280 °C / Cone 4–9, with a standard 1220 °C / Cone 6 firing and a 20-minute soak. By The Sea is listed at 1180–1280 °C / Cone 4–9, except K005, K013, K014, K022 and K025 at about 1140–1240 °C / Cone 2–6.
Use the same clay body and firing program you expect to use in production. Record the peak temperature, hold, cooling schedule, and kiln position so you can repeat a successful result.
Can I combine collections?
The supplier notes describe Bright with Matt for a satin look, Bright or Matt with Vibes for reactive effects, and Vibes as a top coat over Crystal. These are useful starting points rather than guaranteed formulas.
Test the base and top order, coat counts, and overlap area. Change one variable at a time and record the sequence on the tile. Reactive combinations may move more than either glaze alone, so keep the foot clean and use a suitable glaze catcher when the item guidance calls for one.
Why might my fired result differ from a swatch?
Clay color and composition, bisque temperature, surface texture, glaze thickness, layer order, firing speed, peak temperature, hold, cooling, and kiln position can all change the fired surface. A supplier swatch is a reference point, not a promise of an identical result.
Make test tiles from the same clay body as the finished piece and place them in representative kiln locations. If consistency matters for a production collection, repeat the successful test before glazing the full batch.
How should I label and compare test tiles?
Record the clay body, bisque temperature, glaze name or code, number of coats, application method, and any base/top layer order directly on the tile or in a firing notebook. Add the firing program and kiln position after loading.
Photograph the fired tile in neutral light and keep the notes with it. A small, consistent test library makes it easier to compare finishes and reproduce results later.
Which glazes need extra attention for movement?
The supplier notes say Vibes effects become more pronounced at higher temperatures and that the glaze can run. Crystal guidance also recommends a glaze catcher because the glaze can move during firing. Layered reactive combinations can behave differently from either glaze by itself.
Leave the foot and an appropriate margin unglazed, follow the item guidance, and test the planned thickness and combination before using it on finished work.
Are final prices, sizes, and shipping details available yet?
The current catalog uses a clearly marked US$1 placeholder while E-Glaze completes product and checkout preparation. The displayed amount is not final pricing, and jar sizes and shipping and returns details are still being prepared.
