What is Vitreous Enamel?
Vitreous enamel, also known as porcelain enamel, stands as a testament to the artful fusion of powdered glass onto a substrate through firing, typically at temperatures ranging between 750 and 850 °C (1,380 and 1,560 °F). As the powder melds, flows, and solidifies, it creates a resilient, glassy coating. The term "vitreous" finds its roots in the Latin word "vitreus," signifying "glassy."
