Abstract
Metal coatings for browning dishes to be used in microwave ovens are obtained by use of plastes of: PA0 (a) 50 to 80% by weight of a mixture of PA1 (aa) 5 to 70% by weight of a conductive component formed of 5 to 95% by weight ruthenium oxide, and the balance being at least one of silver, palladium, rhodium oxide and/or bismuth oxide, PA1 (bb) 30 to 95% by weight of a glass frit PA0 (b) 20 to 50% by weight of an organic binder. Coatings which are applied to glass, ceramic and/or vitreous ceramic dishes and cooking vessels are very adherent and in a few minutes reach temperatures of up to 300.degree. C.
