Because they use similar materials and processes, enamels and ceramics share a close relationship. Enamellists work on metal surfaces instead of clay, creating everything from functional jewelry and dinnerware to wall-mounted panels. They use pigments called enamels in the process, which behave similarly to ceramic glazes. Comprising mineral pigments and a glassy powder called frit, enamels can be painted as a liquid or sifted and sprinkled onto a surface while dry. Enameled metal is then fired in a kiln at temperatures ranging from 1400°F to 1650°F. Artists often add additional layers of enamel after cooling and fire their pieces multiple times, which creates seductive, jewel-like surfaces.
