Speedball Underglazes




Speedball Underglazes
Cone 05-10

All Speedball glazes are lead-free and non-toxic. Dinnerware safe when used and fired as directed.

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.
Speedball underglazes fire to a matte finish without a clear overglaze and to a glossy finish with a clear overglaze. It is strongly recommended to use either Speedball's Earthenware or Stoneware clear glazes with Speedball underglazes, depending upon your desired firing temp.
