Collection: Speedball Underglaze

Offering artists spectacular results that fire true consistently, Speedball’s Underglazes are unmatched in vibrancy and value.  Originally formulated to perform in a wide firing range, 05-6, Speedball’s Underglazes have been successfully fired at Cone 10.  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*.  Trusted by some of today’s most well-known and acclaimed ceramic artists, Speedball Underglazes offer incredible quality at an unbeatable price—on average, saving artists over 50% versus leading brands.

*For best results, use Speedball Clear Earthenware or Stoneware Clear Glaze with Speedball Underglazes.
