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.
*Select stoneware products are available in 4oz.
Cone 6 oxidation : Muddy Waters is a matte brown glaze with crystals that melt into a glossy blue. Heavier crystal application will produce more color variation.
Cone 10 reduction : Glossy blue becomes more prominent. Increased movement.
TIP: SW-174 Leather is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-174 Leather with a third coat of SW-179 Muddy Waters.
