What is enamel jewelry made of?

Enamel jewelry is made out of glass and precious metal. The type of glass used to produce enamel jewelry is usually a mix of quartz sand, iron oxide, potassium oxide and borax. Artisans apply this molten mixture to precious metal and then fire it at extremely high temperatures to produce a sleek, hard enamel surface. Explore a wide variety of enamel jewelry on 1stDibs.
