Cone 6: Moonscape is formulated to produce a medium gray to white variegation mottled with black crystals. Light coats will produce a matte gray finish with little white variegation and few crystals. Use three or more coats to produce more white variegation and crystals. At cone 5, this glaze will produce a matte sepia finish with little breaking over texture.
Cone 10: Off-white variation darkens. Gray variation turns blue. Crystals melt.
TIP: SW-137 Storm Gray is the base glaze. For a lighter crystal effect, you may try applying two coats of SW-137 Storm Gray with a third coat of SW-147 Moonscape.
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.
