Enamel (glass)

material made by fusing powdered glass to a substrate by firing

Enamel is made of melted glass, often on metal. Sometimes called vitreous or porcelain enamel, it is made by fusing powdered glass to a base 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 coating on metal, or on glass or ceramics.[1]

It has been used on decorative objects for two, or three thousand years, but especially in the Middle Ages in Europe. In the 19th century, it was used on everyday objects such as kitchen equipment and road signs. The glass is hard-wearing, scratch resistant and easy to clean.
