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.
