    摘要: The present invention concerns a glass ceramic item at least partially covered with at least one layer of an enamel formed by a glass frit of the following composition, the proportions being expressed in percentages by weight: SiO
    2 45 - 60%, preferably 50 - 58%; AI2O3 12 - 22%, preferably 15 - 19%; B2O3 12 - 22 %, preferably 15 - 19%; Li2O 0-5%, preferably > 0 - 5%; Na2O 0 - 2%; K2O > 2%; CaO 0 - 4%, preferably 0 - 2%; MgO 0 - 4%, preferably > 0 - 4%; ZnO 0 - 4%, preferably > 0 - 4%; BaO 0 - 4%, preferably > 0 - 4%; ZrO2 0 - 4%, preferably 0 - 2%, in particular > 0 - 2%; TiO2 0 - 1 %, preferably 0 - 0.5%; the sum of the oxides CaO + MgO +BaO + SrO + ZnO further being less than or equal to 10%, and preferably being between 2 and 8%. The invention also concerns the enamel and the method for obtaining the glass ceramic item.
