SB Medium Green Underglaze

2oz Medium Green Underglaze

Speedball Underglazes deliver exceptional, consistent results that artists can rely on, providing vibrant color at an outstanding value. Originally designed to perform across a broad firing range of Cone 05-6, these undeglazes have also been successfully fired at Cone 10. Perfect for use on both greenware and bisque, each shade offers a soft, velvety finish when left unglazed and becomes even more intense and rich when covered with a clear glaze. Trusted by renowned ceramic artists, Speedball Underglazes combine top-tier quality with an unbeatable price—typically saving artists more than 50% compared to leading brands.

For best results, use Speedball Clear Earthenware or Stoneware Clear Glaze with Speedball Underglazes.


Speedball is well known for their high quality printmaking inks and are now boasting the same quality in their 24 liquid, opaque ceramic underglaze colors. Speedball underglazes will not move or bleed, making them perfect for detailed painting, sgraffito and design work. Apply them directly to greenware or bisque, or blend colors together to create specific shades. Apply a clear coat of low fire or high fire glaze to finish and make dinnerware safe.
