Duncan's crystal glazes create uniquely bright, multicolored bursts and specks when fired. The results appear different every time. With Crystals Glazes™, color crystals move throughout the glaze during firing, creating a distinctively interesting appearance. Each result depends on the size of the crystal, slope of the piece and temperature of the fire. Like the excitement of fireworks festivities, you'll love the pops of color from Crystals Glazes™!
Duncan recommends stirring the glaze without disturbing the crystals and applying the first two coats. Mix the crystals in for the third coat and avoid applying a heavy amount of crystals near the bottom of the piece. Duncan Crystal Glazes should be applied to cone 04 bisque ware and fired to cone 06.
