  • Patent number: 6936556
    Abstract: The present invention provides partially crystallizing lead-free and cadmium-free glass enamel composition that fuse at low temperatures. Glass enamel compositions according to the present invention form predominantly bismuth titanate and optionally zinc titanate crystals upon firing. Preferably, glass enamel compositions according to the invention include a glass component that includes by weight from about 11% to about 52% SiO2, from 10.2% to about 40% TiO2, from about 5% to about 75% Bi2O3, up to about 8% B2O3, up to about 14% BaO+SrO, and up to about 45% by weight ZnO, where the sum of Bi2O3 and ZnO comprises from about 30% to about 85% of the glass component by weight.
