Abstract: A process for producing and intermediate layer between a high-melting dental alloy and a dental porcelain which comprises applying to said high-melting dental metal alloy a composition comprising.(a) at least a metal or a metal alloy which is thermally stable at a temperature of at least 800.degree. C.;(b) gold or a gold compound which decomposes to metallic gold, or a gold alloy;(c) at least one flux; and(d) aluminum and/or solver or an aluminum-silver alloy or a silver compound which decomposes two metallic silver, in a liquid vehicle (A) in which component (c) is at least partially soluble, drying the so-treated high-melting dental metal alloy and sintering said composition and thereafter treating the so-sintered composition with a liquid (B) in which the non-metallic components of said composition are at least partially soluble.
