Porcelain enamels are glass coatings applied primarily to products or parts made of sheet steel, cast iron, or aluminum to improve appearance and to protect the metal surface. This article provides information on the types and properties of the porcelain enamels and frits for porcelain enameling. It describes the corrosion resistance of the porcelain enamels in a variety of environments. Evaluation of properties of the porcelain-enameled products to control specifications and quality of porcelain-enamel coatings is also reviewed. The article contains a table that lists the specific test methods for evaluating various properties of porcelain enamels.
