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.
