i) providing a glass beverage container;
ii) providing a decorative lead-free glass enamel comprising a glass frit, the glass frit comprising in weight percent from 17% to 28% SiO.sub.2, from 12% to 30% B.sub.2 O.sub.3, up to 3% Al.sub.2 O.sub.3, up to 13% Na.sub.2 O, up to 13% K.sub.2 O, up to 14% TiO.sub.2, from 5% to 30% ZnO, up to 14% ZrO.sub.2, up to 6% CeO, up to 6% Y.sub.2 O.sub.3, from 1% to 8% La.sub.2 O.sub.3, up to 1% MgO, up to 5% CaO, up to 10% SrO, up to 16% BaO, from 0.5% to 5% fluoride, a maximum of 5% each of WO.sub.3, P.sub.2 O.sub.5, Bi.sub.2 O.sub.3, Sb.sub.2 O.sub.3 and MoO.sub.3, with the provisions that the sum of the levels of plus Na.sub.2 O plus K.sub.2 O is in the range of 6% to 13%, that the sum of the levels of MgO plus CaO plus SrO plus BaO is in the range of 1% to 16%, and that the sum of the levels of ZrO.sub.2 plus TiO.sub.2 plus La.sub.2 O.sub.3 plus CeO.sub.2 plus Y.sub.2 O.sub.3 is in the range of 7% to 25%;
iii) applying the glass enamel to at least a portion of the surface of the glass beverage container; and
iv) firing the glass beverage container at a temperature of from about 560.degree. C. to about 640.degree. C. so as to produce a resilient decorative coating on the surface of the beverage container.
