Astro Gems™ are an underglaze-based textural glaze that contains tiny crystals. When fired, these crystals provide jewel-like spots on the matte surface of the glaze. Astro Gems™ can be applied to both green-ware and bisque.
Astro Gems™ are certified AP non-toxic. As surfaces may be difficult to properly clean if in contact with food, we recommend Astro Gems™ be used on decorative ware.
