Enamel
What is Enamel?
Enamel is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating on metal, glass, or ceramic. Enamel can be used to create a variety of decorative effects, including color, pattern, and texture. It is known for its durability, resistance to corrosion, and vibrant colors. Enamel is used in jewelry, art, and industrial applications.
