Cone 6: Base glaze remains - crystals fade completely. Enhanced mobility. Surface issues may occur.
Mayco’s Jungle Gems are gloss glaze bases with pieces of glass frits that melt during the firing process. As the crystals bloom, they produce dramatic, colorful effects. We call it "Art in a Jar". Combine Mayco crystal glazes with other Mayco glazes, such as Stroke & Coats and Foundations for unique glaze combinations. For mid-range fire artists, the Jungle Gem glazes maintain their color with increased crystal movement at the higher temperature. Jungle Gems are non-toxic, and safe for use by artists of all ages. Not recommended for dinnerware due to surface characteristics.
