AstroGems

Astro Gem® is non-moving textural glaze that contains two sizes of tiny crystals. When fired these crystals provide a quartz-like gleam projecting from the matte surface of the base glaze. The base glaze is an underglaze and will remain porous after firing.

Many Mayco low fire (cone 06) glazes can be fired to Cone 6. A description of the Cone 6 results are on the product label. Always test and protect your kiln shelves when testing a glaze to a temperature higher than the recommended firing temperature. !
