Vitreous enamel

Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating on metal, or on glass or ceramics. The term "enamel" is most often restricted to work on metal, which is the subject of this article. Enameled glass is also called "painted". Fired enamelware is an integrated layered composite of glass and metal.
