Jewelry Enamels with a Decreased Lead Oxide Content

The effect of aluminum and cadmium oxides on glasses of an alkali-containing lead borosilicate system with a small amount of boron and lead has been studied. The influence of the ratio of aluminum and cadmium oxides on the color of the enamel, as well as on some physicochemical and technological parameters of the enamel is shown. It has been established that, on the basis of this system, it is possible to obtain a low-melting (780 - 800 ° C) corrosion-resistant blue enamel for copper and its alloys.
