Speedball’s Underglazes offer artists spectacular results that burn consistently across most of the color gamut, and are unmatched in vibrancy and value. Originally formulated to perform in a wide firing range, 05-6, Speedball’s Underglazes have been successfully fired on Cone 10. Suitable for use on green earthenware or bisque, each color produces a softer, velvety finish when left unglazed, and becomes more intense in richness when covered with a clear glazeFor best results, use Speedball Clear Earthenware or Stoneware Clear Glaze with Speedball Underglazes. Speedball recommends making test tiles to match the artist’s clay body and firing schedule.
All colors are safe for dinnerware if used and fired as directed, are lead-free and carry the AP Seal. For best results, use Speedball Clear Earthenware or Stoneware Clear Glaze with Speedball Underglazes. Speedball recommends making test tiles to match the artist’s clay body and firing schedule.
