Abstract: A glass-ceramic plate for a cooking device includes a first main face to be in contact with liquids, a second main face and an edge, a liquid-retaining bead fastened to and in contact with the first main face, wherein the retaining bead surrounds a region of the first main face so as to form a liquid-retaining reservoir, and includes at least two hydrophobic sub-beads inscribed within one another and separated by hydrophilic zones, a width of the hydrophilic zone between two consecutive sub-beads is throughout at least greater than 500 ?m and less than a threshold value, the threshold value being defined so that, when a liquid is present in the hydrophilic zone, a variation in the retention time or volume of the liquid before overflowing, relative to a same liquid present in a hydrophilic zone, the width of which is greater than the value, is less than 5%.

Abstract: A process for the manufacture of a glass-ceramic article exhibiting properties of resistance to scratches, greasy marks, adhesion of dirt and light scattering. The glass-ceramic article includes a surface, the surface arithmetic roughness of which is between 2 ?m and 7 ?m and the roughness being obtained using a chemical surface treatment. The glass-ceramic article is particularly suitable for use as a cooking surface and/or as surface for the preparation of foodstuffs.

Abstract: An item, in particular for domestic and/or furniture use, in particular a countertop or furniture unit, includes a carcass on which a glass-ceramic assembly is arranged, the glass-ceramic assembly including a glass-ceramic plate and an electronic module including at least one heating element, the carcass including a support surface on which the glass-ceramic plate is placed and fastened and a housing in which the heating element is arranged, wherein the glass-ceramic plate bears a fastening system for reversibly fastening it to the carcass.

Abstract: A glass, in particular glass-ceramic, article, which is intended in particular to be used with at least one heating element, is formed of at least one substrate, such as a glass-ceramic plate. The substrate is at least partly coated with at least one layer of ink, which is advantageously deposited by inkjet printing. The ink is formed of nanoscale pigments and of at least one silicone binder. The layer of ink is coated with at least one layer of silicone-based paint. The layer of paint advantageously is deposited in the form of a flat tint, in particular by screen printing, and preferably being opacifying.

Abstract: The present invention relates to a glass-ceramic article comprising at least one substrate, such as a plate, made of glass-ceramic, said substrate being coated in at least one area with at least one enamel coating such that: 1) the enamel has a gloss at 60° of less than 40, 2) the coverage rate of said enamel in said area coated with said coating is 40 to 80%, 3) said enamel comprises pigments in the form of mica and/or aluminum oxide and/or silica particles coated with metal oxides or combinations of metal oxides, 4) said enamel has a roughness Ra greater than or equal to 0.4 ?m, 5) said enamel has a roughness Rt greater than 4 ?m.

Abstract: A mineral ink for inkjet printing on a mineral substrate, includes a glass frit, an organic solvent, a dispersant, a surfactant and a glass fit including the following constituents in the weight limits defined below expressed as percentages by weight of the glass frit: 35 to 50% of SiO2, 15 to 25% of Al2O3, 1.5 to 4% of Li2O, 22 to 32% of B2O3, 0 to 2% of Na2O, 2 to 5% of K2O, 1 to 5% of CaO, 1 to 4% of ZrO2.

Abstract: The present invention relates to a glass-ceramic article comprising at least one substrate, such as a plate, made of glass-ceramic, said substrate being coated in at least one area with at least one enamel coating such that: 1) said enamel has a gloss at 60° of less than 40, 2) the coverage rate of said enamel in said area coated with said coating is 40 to 80%, 3) said enamel preferably: 3a) is free of pigments in the form of mica or aluminum oxide or silica particles coated with metal oxides or combinations of metal oxides, and 3b) has a roughness Ra greater than or equal to 0.4 ?m and/or a luminosity L* greater than 50.
