Enamelling
A layer of glass or resin (plastic) can also protect metal. It is used on some household metal goods and (whether glass or resin) is called enamel. Enamel is commonly applied to kitchen appliances such as cookers and dishwashers. The enamel layer does not react with water (it is inert), and at the same time, it sticks hard
to the steel and has an attractive appearance. Baths made of steel are also enameled. Because most enamel is a poor conductor of heat, the bases of enameled pots and pans are not enameled. Glass-enameled surfaces are brittle and liable to chip, resin ones far less so.
(Below) Enamel paint can often be distinguished by its slightly rippled effect when seen in reflective light.
(Below) The blue cooking pots in the foreground of this market scene are old- fashioned enameled pots with a glass surface coating on metal. The surface is hard but brittle, as shown by this detail (left).
