All about Jungle Gems

Unleash your creativity with Mayco’s Jungle Gems™ Crystal Glazes. These stunning glazes allow ceramic artists to easily add color and depth to their designs. Use alone for stunning effects, in glaze combination blending with Stroke & Coats®, Foundations® or Cobblestones, or simply as an accent to your design.

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.

General Use:
Crystal glazes were designed to mature at cone 06/05.
Shake the jar well and stir during the application process. Stir frequently as the crystals tend to settle in the jar due to their weight.
Apply two to three even coats to shelf cone 04 bisque with a fan brush, allow to dry between coats. We recommend a soft fan brush, such as CB-604 #4 or CB-618 #8 Soft Fan, for glaze application.
Re-distribution of crystals may be required during the final coat. Where you see the crystal on the piece, is where it will 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.
As that surface may be difficult to properly clean when it comes into contact with food, we recommend Jungle Gems™ Crystal Glazes to be used on decorative ware.
Jungle Gems™ Crystal Glazes have been formulated to mature at cone 06/05. However, they can be fired at higher temperatures. Their performance at cone 6 is noted on each individual product label.

NOTE: 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.
