SW-222 Green Jasper

Description

Stoneware crystal glazes are designed to expand upon the surface with dazzling bursts of color. Fired results will vary based on ware’s orientation. Crystals will settle to the bottom of the jar and will need a good mixing prior to initial use. Re-stir between each coat. Stir with palette knife or other unpainted tool. Avoid placing crystals near the bottom third of a vertical piece as they may cause additional movement during firing. Crystals will flow more than the base glaze. While the glaze is wet, use your fan brush to redistribute the crystals to achieve balanced coverage. Over-application or heavy deposition of the crystals can cause pinholing or running. When storing a crystal glaze, you may consider storing upside down to facilitate crystal dispersion on the next use.

Chips shown are fired flat on a white clay body fired to cone 6 oxidation and cone 10 reduction. The choice of clay body, the thickness of glaze application, the firing process, and temperature will affect the fired results.

Tips:

Green Jasper uses SW250 White Opal as the base glaze.
Upon opening, crystals will be concentrated in the bottom of the bottle. Stir/shake thoroughly to incorporate before each use.
Crystals can create movement. Avoid having a heavy concentration of crystals near the bottom of your piece.
When storing a crystal glaze, you may consider storing upside down to make crystal more accessible.
Can be used in oxidation or reduction firings. Results may vary.
The choice of clay body, thickness of glaze application, firing process and temperature will affect the fired results. Always test in your kiln, on your clay body.
