Enamel
A smooth, glossy material made from soft glass, obtained by adding metal oxides to a base enamel paste. Colours are painted or printed on to a hard surface and then fired, creating a permanent, glossy finish. Today the word 'enamel' is used loosely to describe a glossy protective covering applied to the surface of objects made from metal, wood or ceramic.
