This is the recipe for the MoonCrater White cone 6 oxidation glaze that I use in my electric kiln. It's a fairly standard white satin matte glaze that I ran across in a February 2003 Ceramic Monthly. The only change I've made was switching out Tin Oxide for Zircopax as a opacifier to give me a softer white.
Gerstle Borate 31.6%
Kona F-4 Feldspar 19.8%
It's faults are what makes this glaze so interesting . When it's overfired on a cone 5 clay body, the glaze develops a rich creamy semi-translucent white satin matte that's inclined to develop patches of wonderfully textured orange peel effects that often transition into shallow open soft edged craters. This is a pleasantly usable texture glaze.
