The present invention relates to a glass-ceramic article at least partly coated with at least one layer of an enamel formed from a glass frit having the following composition, the proportions being expressed as weight percentages: 

Glass-ceramic article and enamel suitable for the coating thereof

A glass-ceramic plate for covering or accommodating at least one heating element, wherein the plate is at least partly coated with at least one nanoscale layer based on a metallic material having a refractive index greater than the refractive index of the glass-ceramic.

Glass-ceramic plate and its manufacturing process

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: the sum of the alkaline-earth metal oxides CaO+BaO moreover being between 8 and 15%, and the sum of the alkali metal oxides NaO+KO+LiO moreover being between 7 and 20%. The reinforced glass-ceramics obtained by the process.
