Last year I started to use an ash glaze and really liked it. I have been doing some testing to change the color and I have been testing out other ash glaze recipes.
All of the test tiles are stoneware. They were fired in a gas kiln to cone 10 (2350 F). Each test tile was dipped once and then a second time halfway down.
Base Ingredients
- 31 - Whiting
- 24 - Kentucky Ball Clay

Add the below colorants to base glaze

Do not use the base ingredients and only use these two ingredients for this ash glaze.
