WHAT IS ENAMELED COPPER?
Enameling is glass fused to metal at high heat. Enamels are finely ground glass, like fine sand (or even more finely pulverized and mixed with an oil or adhesive). They may be opaque or transparent; their colors come from the use of various oxides.
Enameling is characterized by brilliant, non-fading colors, tremendous durability, variety of color effects depending on angle of light, and tremendous versatility – from jewelry (many people are familiar with cloisonne, which is a type of enameling), to bowls and wall pieces, to large-scale interior or exterior murals. The medium of enameling goes back two thousand years and forms part of the artistic heritage on six continents.
