Porcelain enamel was the original product of Ferro Corporation, which started in business in 1919, almost 100 years ago. The original factory in Cleveland Ohio, U.S.A. continues to produce porcelain enamel today.
In addition, Ferro invested in factories in many countries around the world, manufacturing vast quantities to satisfy the growing global demand for the products. Ferro South Africa (Pty) Ltd, originally a Ferro Corp plant, has produced porcelain enamel on an uninterrupted basis for more than 60 years.
Porcelain enamel or vitreous enamel is a glass that is bonded to metal, generally low carbon steel, stainless steel, cast iron or aluminium, at temperatures from as low as 530° C for aluminium to 900° C for cast iron. The company pioneered ready to use, as well as ready mill, porcelain enamel formulations, which require no adjustments or modifications prior to their applications.
The electrostatic application of porcelain enamel in a powder form, an earlier development by Ferro, continues to give manufacturers an energy efficient and environmentally friendly alternative to conventional wet application. It also provides a thinner and better finish coating to wet applied porcelain enamel.
