Flame Red Underglaze 001076

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.
