The same glaze wall, sorted 16 ways

These all pull from the same wall, sorted different ways. Some by what a glaze does on a pot. Some by what your level includes. Some by what we reach for ourselves. Open the one that matches the question you actually have.

Glazes by Membership LevelEvery glaze sorted by the level that opens it, and what each jump actually buys you. Test Tile FinderHolding a test tile pot? Find it here and read every tile on it in order. ❤️ Studio FavoritesThe glazes we keep coming back to, chosen on behavior rather than looks. Owner's FavoritesThe glazes the owner actually reaches for, including the ones nobody else picks up. Good for TextureThe glazes that show your carving instead of filling it in. Layering GlazesOne glaze over another. Twenty five pairings worth firing, and how to get them right. Metallic GlazesMetal rather than glass. Spectacular when they land, and the least forgiving glazes we stock. Satin and Matte GlazesEverything that is not shiny. Soft light, real texture, and the surface people want to touch. All the CeladonsEvery celadon we stock. The shelf to reach for when the carving is the point. All the ShinosEvery shino we carry. Warm, broken, and almost never the same twice. Translucent GlazesThe glazes you can see through. The clay underneath stays part of the finished pot. All the UnderglazesEvery underglaze on the shelf. The range you draw with, and it holds an edge. Raku GlazesEvery raku glaze we carry. Not shelf glazes, and never in the regular kilns. Our Flux GlazesNot colors. Solvents. They melt further than what is under them and take it with them. Food Safe GlazesSearch any glaze we carry for a straight answer, and the maker source behind it. Liner GlazesMade for the inside of the pot, so the outside can be as wild as you want.

The rabbit hole

8 makers, 42 families of glazes and underglazes. Open one to see its families, or go straight to the brand.

About these images and what your pot will actually look like

We have done our best to represent every glaze here accurately, and you should still expect your pot to look different from what is on this screen.

Our glaze tile images are digitally created. They are built to show the character of a glaze, not to be a color match.

A screen is not a printout, a printout is not a test tile, and a test tile is not a finished pot. Each step in that chain shifts what a glaze looks like, sometimes a lot.

On top of that, the pottery itself changes the result: the clay body, how thick the glaze went on, whether it was brushed, dipped or sprayed, what was layered under or over it, where the piece sat in the kiln, how hot that spot ran, how fast it cooled, what was fired next to it, and how much texture the surface had. Two pots glazed from the same jar on the same day can come out different.

Treat every image here as a starting point, and treat a test tile fired on your own clay as the real answer.
