VITREOUS ENAMEL
Vitreous enamel is the colourful result of fusing powdered glass to a surface, such as cast iron, by firing it at an extremely high heat in a furnace at a temperature between 750 and 850 degrees centigrade. It is the firing process that gives vitreous enamel its unique combination of properties.
Vitreous enamel has many excellent properties. It is smooth, hard, chemically resistant, durable, can be blended into brilliant, long-lasting colours, and cannot burn.
The colours are produced with the addition of various minerals, often metal oxides cobalt, praseodymium, iron, or neodymium. Enamel can be transparent, opaque or translucent.
