Offering artists spectacular results that fire true across the vast majority of the color range 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. All colors are dinnerware safe when used and fired as directed, are lead-free and carry the AP Seal.
