Enameling meets decorative as weU as protective requirements. Ceramic enamels are mainly based on alkaH borosiHcate glasses. The part to be enameled is dipped into or sprayed with a sHp, ie, a water suspension of glass fragments called frit. The sHp coating is dried and fused in an enameling furnace under careful heat control (see Enamels, porcelain or vitreous). [Pg.46]
