|Custer Feldspar (sub. Forshammer)||27.00|
Specific gravity: 1.43. A dolomite matte, this glaze has a smooth, thick surface. On a darker clay body, the glaze becomes darker and shows some speckling. With cobalt carbonate, it produces a lavender-violet color. I substituted Forshammer feldspar for Custer feldspar.
