Summary

This paper describes innovative talc pottery slips and lead-free, dinnerware-safe glazes firing at cone 05-1/2 made with zinc borate. The cost of these glazes is about $.45/lb and, since they are stirred glazes, they need no ball milling. 0.1-0.2% of magnesium hydroxide can be used to keep glaze slurries from hard sediment for years. Cone 05 semi-vitreous talc bodies can be made as strong as 12 000 psi by using a special zinc borate flux system. Bright, hard glazes have been developed.
