Instructions


Specific gravity: 1.40. Eggshell glaze has a strong breaking white effect against a glossy rust background. I substituted Forshammer feldspar for Custer Feldspar due to availability, and used JM frit 169 in place of Ferro frit 3124 in this glaze. These frits are not similar. JM frit 169 has no alumina and includes barium.
