Description
A hard, vitreous porcelain-like coating on metal, glass, or ceramic. Enamel's smooth, shiny surface is made from powdered fusible glasses and opaque colorants (i.e., cobalt blue, tin oxide) mixed with oil or water, then painted or sprayed on the object and fired up to 800C (1500F). The enamel fuses to the surface of the substrate forming a thin, continuous protective film. Enamel was used by the Greeks in the 4th c. BCE to decorate jewelry and ceramics. Later, artists used enamels to decorate small metal objects, book covers, crosses, and to paint miniature portraits. Low temperature, or soft, opaque enamels are used for coating aluminum for cooking utensils, signs and dials. High temperature, or hard, enamels can be translucent or transparent. Initially the metal bases for enamels were gold or silver, but copper was increasingly used in the 18th century for small decorated items such as snuff boxes. Porcelain enamels have been used in building construction since the late 19th century. For architectural enamels, the opaque vitreous coatings were most commonly applied to iron, aluminum, and stainless steel subtrates. Sheets, panels and tiles were used for interior and exterior surfaces, such as in the White Castle restaurants built in the 1920s.
