Instructions


This is a cone-11 glaze that likes a 10-minute soak at the end of the firing and works best with a slow cool. It turns out equally well in reduction or oxidation. I have an electric kiln that I'll use to fire the glaze to cone 11 and it comes out beautifully. The glaze looks really clean on porcelain, but I also use it on a grogged stoneware with tiny specks of iron with nice results. It doesn't run very much, so it can be applied pretty thick. I always pour my glazes to get the bit of drip on the outside.
