"vitreous enamel"的定义和意义

What is "vitreous enamel"?

Vitreous enamel is a technique of applying a glass-like coating to metal surfaces. This involves fusing powdered glass to the metal by heating it to high temperatures, where it melts and bonds to the surface, creating a smooth, durable finish. The result is a glossy, colorful coating that can be used for decorative items such as jewelry, artwork, and pottery. Vitreous enamel provides both a protective layer and an attractive finish, allowing for vibrant colors and intricate designs.
