Enamel
Enamel is a glasslike substance used primarily to form a smooth, glossy surface on metal. It can be any of various colors and is used to decorate many kinds of articles, including metal cups, dishes, and plates. Enamel also provides a tough protective surface for bathroom fixtures, kitchen appliances, various types of industrial equipment, and many other items. Metal articles decorated or protected with enamel are called enamelware or, simply, enamels. The word enamel is often used to refer to the glasslike substance applied to ceramics. However, the correct name for this substance is glaze. The word enamel also refers to a type of paint that forms a hard, glossy surface when dry. This enamel paint can be applied over a glaze as a decoration.
