If you love layers, coat your pieces with 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-Coats 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 Underglazes or E-Z Stroke Translucent Underglazes. Mix well. Apply 3 coats to greenware or cone 04 bisque for opaque coverage. Fire greenware to cone 04. Apply and fire clear glaze per label. Water clean up.
