Crystal glazes were designed to mature at 1015 -1030°C. Shake the jar well and stir during the application process. Apply two to three even coats to 1060°C bisque with a fan brush, allow to dry between coats. We recommend a soft fan brush for glaze application. Stir frequently as crystals tend to settle in the jar due to their weight. Re-distribution of crystals may be required during the final coat. Where you see the crystal is where you will see it bloom. Avoid heavy application of crystals at the bottom of ware as the crystals bloom and can adhere to the kiln shelves or stilts. The crystals in the glaze will melt when fired, which may create a textured surface. Jungle Gems™ Crystal Glazes have a natural crazing that occurs when the crystals “bloom”. 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™ Crystal Glazes have been formulated to mature at 1015-1030°C. However can be fired at higher temperatures. Their performance at 1230°C 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.
