Speedball Earthenware Glazes offer artists spectacular results with brilliant colors that fire true consistently. These glazes are designed for use on pottery clays bisqued to Cone 04 and fired to Cone 05-06. All colors are dinnerware safe when used and fired as directed. All colors are lead-free. For best results, apply 2-3 liberal coats.

Compatible with Speedball Underglazes and suitable for use on greenware or bisque, each color produces a softer, velvety finish when left unglazed, and intensifies in richness when covered with a clear glaze.
