Duncan CR933 Fireworks Crystal Glaze
Apply to shelf cone 04 bisque. Shake jar well and stir during the application process. Apply 3 coats with a fan brush, allow to dry between coats. Avoid placing crystals towards bottom of ware to keep them from flowing onto the kiln shelf during firing. The crystals in the glaze will melt when fired. Crystal glazes are designed to mature at cone 06/04.
