Zusammenfassung:	This invention relates to a lead-free glass coating made by firing a lead-free glass enamel composition comprising a glass frit having by weight from about 20% to about 40% zinc oxide, from about 20% to about 32% boron oxide, and from about 10% to about 30% silicon dioxide, from about 0% to about 12% titanium dioxide, from about 4% to about 12% sodium oxide, from about 0% to about 10% potassium oxide, from about 0% to about 12% zirconia, up to about 4% alumina, up to about 5% lithium and up to about 5% fluorine. The lead-free glass coating exhibits excellent adhesion and improved acid resistance.
