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 have been formulated to mature at cone 06/05. However can be fired at higher temperatures. Their performance at cone 6 is noted on each individual product label. Crystals tend to flow at higher temperatures so take care on vertical pieces. We recommend testing on your clay body and in your kiln prior to use.
