One of the Stoneware crystal glazes, designed to expand upon the surface with dazzling bursts of color. Fired results will vary based on ware’s orientation.
Cone 5/6 to cone 10.
General Appearance of Midnight Rain
Cone 6: A blue-green breaking gloss glaze that contains black crystals. As the crystals melt and move, a black oil-like streak is created in the glaze.
Cone 10: Crystals melt and integrate into base glaze, darking the color. Increased movement.
- Blue Surf (GL-16SW100) is the base glaze.
- Crystals will settle to the bottom of the jar and will need a good mixing prior to initial use. Re-stir between each coat.
- 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 a fan brush to redistribute the crystals to achieve balanced coverage.
- Over-application or heavy deposition of the crystals can cause pinholing or running.
- For a lighter crystal effect, try applying two coats of Blue Surf(GL-16SW100) with a third coat of Midnight Rain.
- Always test prior to use.
