If you love layers, coat your pieces with Duncan® Cover-Coat® Opaque Underglazes! Applied directly to greenware, soft-fired bisque or bisque, these underglazes provide solid coverage over even the darkest colors, and are perfect for airbrushing and brushwork. Cover-Coat Underglazes fire to an opaque, porous matte finish and are safe for food when a Duncan food-safe clear glaze is applied over them. For custom colors, tint them with other Cover-Coat colors or Duncan® E-Z Stroke™ Translucent Underglazes. Colors are available in 2-oz. squeeze bottles and assorted colors are offered in pint and gallon sizes.
