Enamel or vitreous enamel coating is really a thin layer of glass fused by heat on to the surface of a metal.
Vitreous enamel coating is part of everyday life and found all around us. It covers many kitchen surfaces including cookers, saucepans and washing machine drums. You will find vitreous enamel coating covering cast iron or steel baths and clock and watch faces. Vitreous enamel coating is also used by artists and in jewellery, famously in Russia’s Fabergé eggs.
Out of doors, we use vitreous enamel coating for street signs, Underground station signs, architectural panels, storage tanks and in lots of other places. It is selected because it is weatherproof, vandal resistant, fire proof and because it lasts and lasts and lasts. The Titanic’s Captain Smith’s bathtub vitreous enamel coating has survived very well under the sea.
We make vitreous enamel coating by melting tiny coloured glass particles on to red-hot metal in 800 degrees C furnaces. As it cools it fuses to give glass-coated metal. It all started 3500 years ago in Cyprus. Since 1500 BC enamelling has provided a wonderful, durable, attractive and reliable material.
