A glass-ceramic article is at least partly coated with at least one layer of enamel, including a glass frit. The frit includes, expressed by weight, SiO2, 45-60%; Al2O3, 12-22%; B2O3, 12-22%; Li2O, 0-5%; Na2O, 0-2%; K2O, >2%; CaO, 0-4%; MgO, 0 - 4%; ZnO, 0-4%; BaO, 0-4%; ZrO2, 0-4%; and TiO2, 0-1%. The sum of oxides CaO+MgO+BaO+SrO+ZnO is at most 10%, preferably from 2 to 8%. A process can be used to obtain the article. |
