## Description

World-renowned and up-coming artists alike are using Speedball Underglazes exclusively due to their incredible performance, value, and versatility. Offering spectacular results that fire true consistently, Speedball’s Underglazes feature intense color that is unmatched in vibrancy and layering capabilities superior to all others on market. Speedball Underglazes can be used to create designs and patterns that will come through the glaze covering them, allowing for more visual depth and character. Trusted by some of today’s most well-known and acclaimed ceramic artists, Speedball Undedrglazes are ideal for a detailed painting, sgraffito decoration, watercolor effects, free brush painting, and mishima decoration.  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. These opaque underglazes will not move, flow, or bleed during firing. For best results, apply 2-3 liberal coats and pair with Speedball Earthenware or Stoneware Clear Glaze.  Originally formulated to perform in a wide firing range, Cone 06-6, these underglazes can be successfully fired at Cone 10. All colors are dinnerware safe when used and fired as directed with a covering glaze, lead-free, and carry the AP Seal.
