ABSTRACT:
There is provided a process for the production of firing stable yellow to red glaze mixtures for ceramic products containing as a color carrier cadmium sulfide and/or cadmium sulfoselenide, the glaze mixture consisting of 60 to 98 parts by weight of a base frit, 2 to 40 parts by weight of a color frit, and the customary amounts of suspension agents, in which the base frit can be any frit (known in itself) and the color frit consists of cadmium, sulfur and selenium containing compounds and a so-called base glass, which is composed of one or more known glaze frits. There is added to this color frit one or more glaze stable compounds in an amount of 25 to 95 weight % annealing carried out, at temperatures above 850.degree. C. and subsequently the color frit mixed with the base frit and suspension agent. The glaze stable compound is zirconium oxide, zirconium silicate, tin oxide, cerium oxide, aluminum oxide or titanium oxide.
