My Recipes:

Below are a collection of recipes that I use regularly. I fire to cone 6 in oxidation. I have altered some of the original bases using Hyperglaze, a computer program which I recommend. Although I have been using some of these glazes for a couple years, you should always test them before using them for yourself.

Firing Schedule:

When firing in an electric kiln which is operated by a computer, one has the advantage of being able to easily control the rate at which the kiln cools. Many of my glazes are dependent upon a slow-cool to develop their opacity and crystals. This is especially true of my version of “Wonder Glaze”. It will look very shiny if the kiln is allowed to cool all on its own, but matt/crystalline when using this program.
