Summary:A process for reinforcing a glass-ceramic article, into which a maximum tension is introduced beneath the surface of the glass-ceramic, advantageously in proximity to said surface. The invention also relates to an enamel that can be used for this reinforcement, this enamel being formed from a glass frit having the following composition, the proportions being expressed as weight percentages: SiO2 50-66% MgO 3-8% Na2O  7-15% K2O 0-3% Li2O  0-12% CaO  0-10% BaO  0-15% Al2O3 0-3% ZrO2 0-3% ZnO 0-5% B2O3 0-8% the sum of the alkaline-earth metal oxides CaO+BaO moreover being between 8 and 15%, and the sum of the alkali metal oxides Na2O+K2O+Li2O moreover being between 7 and 20%. The reinforced glass-ceramics obtained by the process.
