Abstract
A cooking receptacle is provided having a browning coating for microwave ovens, and a method of forming such a coating. Said coating, which is external, includes essentially a heating layer made from leadless enamel in which are incorporated electrically conducting elements in the form of a metal powder, this powder being intimately mixed with the enamel, generally in a proportion of 15 to 40% by weight; a protective layer of leadless enamel advantageously covers the heating layer. The layers are deposited on the external surface of the receptacle by silkscreen printing or by decalcomania or by a transfer method and they are subjected to baking at a temperature between 620.degree. and 800.degree. C. The metal powder is formed from at least one substance chosen from the electrically conducting metals such as zinc and the transition elements, the oxides of these metals, and mixtures of these substances.
