Crystalites Glazes - These beautiful glazes transform in the kiln when small pieces of glass burst into color and intricate pattern during the firing process. Use alone for stunning effects, in glaze combination blending with Stroke & Coats, Foundations or Cobblestones or simply as an accent to your design. General Use Crystal glazes were designed to mature at cone 06/05. Apply to shelf cone 04 bisque. Shake jar well and stir during the application process. Apply 3 coats with a fan brush, allowing to dry between coats. Avoid placing crystals towards bottom of ware to keep them from flowing onto the kiln shelf during firing. Crystal Glazes can be fired to higher temperatures. Review individual color label for cone 6 firing results. The crystals in the glaze will melt when fired, which may create a textured surface. As that surface may be difficult to properly clean if in contact with food, we recommend crystal glazes to be used on decorative ware. Jungle Gems and Crystalites glazes are certified AP nontoxic, with the exception of CG 707 Woodland Fantasy and CG 713 Peacock Green which require a caution label, CL, due to soluble copper. Please refer to label for specific information.
