Speedball Underglazes

Speedball’s Underglazes give clay artists a painter’s palette of color to work with, offering smooth, brushable applications that stay true from raw to fired. They can be applied to greenware or bisque, used under a clear glaze for brightness, or left unglazed for a softer, matte look. With their wide range of mixable hues, Speedball underglazes encourage experimentation and give potters the same freedom as working with paint on canvas.
