Speedball Stoneware Glazes – Discontinued Mid-Range Cone 5–10 Line

This product line has been discontinued. Remaining inventory available while supplies last.

Originally developed for Cone 5–6 firing, Speedball Stoneware Glazes could also be fired successfully to Cone 10. This now-discontinued line included 24 vibrant and reliable glaze colors featuring transparent finishes, brights, and beautiful mottled effects.

Formulated for smooth application and consistent results, these glazes were a go-to for both studio artists and educators. All colors in the line were lead-free and dinnerware safe when used and fired as directed.
