Specific gravity: 1.43. This glaze is opaque and glossy, but has a soft sheen on the surface. Many color variations were possible, all of which are opaque, bright, and clean. For color variations, omit the tin oxide, titanium dioxide, and zinc oxide. I substituted Forshammer feldspar for Custer feldspar.
