Abstract
This invention relates to glass and enamel compositions. The glass compositions comprise SiO2, Cs2O, Na2O, ZnO, B2O3, and TiO2, and optionally Bi2O3 and F. The resulting compositions can be used to form an enamel on a substrate, for example, to decorate and/or protect the substrate.
Claims19
An enamel composition comprising a solid portion comprising a frit portion, the frit portion comprising, prior to firing:
- about 30 to about 50 wt % of SiO2;
- about 4.5 to about 20.2 wt % of Cs2O;
- about 6.1 to about 11.5 wt % of Na2O;
- about 6.5 to about 20.2 wt % of B2O3;
- about 8 to about 25 wt % of ZnO;
- about 3.4 to about 12.3 wt % of TiO2;
- about 0 to about 40 wt % of Bi2O3;
- and
- about 0 to about 7 wt % of F.

- about 3.4 to about 12.3 wt % of TiO2;
- about 0 to about 40 wt % of Bi2O3;
- and
- about 0 to about 7 wt % of F;
- and
- firing the enamel composition and the substrate at a temperature sufficient to adhere the enamel composition to the substrate.
