Mayco’s Jungle Gems™ Crystal Glazes transform in the kiln when the small pieces of glass frit burst into color and intricate patterns during the firing process. Artists use these beautiful glazes to add dramatic, colorful effects to their creations. Jungle Gems™ Crystal Glazes can be used alone or in combination with other glazes and can be fired from cone 06 to 6. Refer to the individual color label for cone 6 firing performance. The first photo shows the glaze when fired to cone 06. The second photo is fired to cone 6. Please test on your own clay with your own application and firing. Results WILL vary.
Jungle Gems™ Crystal Glazes have been in the market for many years and were originally formulated using a leaded frit. In 2005, they were converted to a leadless formula, similar to the Mayco Crystalites glaze, which have always been lead-free. We have merged these two great product lines into one, all under the Jungle Gems™ brand. This merge simplifies the selection for the consumer as the glazes perform identically. Crystalite colors will keep their item numbers, name and the entire Crystal Glaze product line remains lead-free.
Jungle Gems™ Crystal Glazes are recommended for ornamental use only when applied to low fire earthenware clay bodies. All but three Jungle Gems™ glazes have been certified as Non-Toxic, suitable for use by artists of all ages when used according to manufacturer’s directions. Jungle Gems™ are not recommended for dinnerware produced from low fire earthenware clay bodies as these glazes can exhibit surface textures such as cracks and crevices. While the glazed surface may pass lead & cadmium leach tests, and therefore legally considered Food Safe, attempts to adequately clean the textured surface may cause the underlying porous ware to absorb water and fail. Jungle Gems™ glazes may be considered dinnerware safe if surface texture is eliminated when firing to mid-range or high fire temperatures. We invite you to unleash your creativity with Jungle Gems™ Crystal Glazes.
