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.

Abstract: The present invention provides a novel enamel composition and a method of using the same to decorate substrates such as a section of glass. The enamel composition comprises a solids portion and a vehicle. The solids portion includes at least one glass frit and a separate and distinct addition of silicon. The solids portion comprises from about 0.01 weight percent to about 20 weight percent metallic silicon.

Abstract: The present invention provides a method of producing an enamel finish on formed section of glass. The enamel composition partially crystallizes upon heating, thereby helping to prevent the forming and handling equipment from sticking and/or adhering to the composition during the forming operation. The enamel composition includes a crystallizable glass frit portion and a seed powder. The crystallized glass frit portion includes precursors from which Zn.sub.2 SiO.sub.4 can be crystallized upon firing of the enamel composition. The seed powder causes at least a portion of the precursors to crystallize upon firing such that during firing at least a part of the crystallizable glass frit yields crystallized Zn.sub.2 SiO.sub.4 formed by the precursors. Preferably, the precursors comprise ZnO and SiO.sub.2, and the seed powder comprises crystalline Zn.sub.2 SiO.sub.4. The enamel composition also preferably includes bismuth oxide (Bi.sub.2 O.sub.
