Abstract: A glass-ceramic article includes at least one substrate, such as a plate, made of glass-ceramic, the substrate having a face including a microtexturing such that the arithmetic mean surface roughness Ra, measured according to standard ISO 4287, is between 0.14 and 0.40 ?m, and the total roughness, Rt, measured according to standard ISO 4287, is between 1.15 and 5.00 ?m.

Abstract: A glass-ceramic article, includes at least one substrate, such as a plate, made of glass-ceramic, the substrate being coated in at least one zone with at least one stack formed 1) of at least one first layer of metal nitride or of semimetal nitride, the first layer exhibiting a thickness of at least 200 nm and a hardness of at least 14 GPa, and 2) of at least one second layer of metal oxide or of semimetal nitride, the second layer exhibiting a thickness of less than 14 nm and exhibiting a coefficient of friction of less than 0.25, the first and second layers being in contact with each other, the second layer being further from the substrate than the first layer.

Abstract: A glass-ceramic article, includes at least one substrate, such as a plate, made of glass-ceramic, the substrate being coated in at least one zone with at least one layer including zirconium silicon nitride, SixZryNz, with an atomic ratio of Zr to the sum Si+Zr, y/(x+y), of 10% to 90%.

Abstract: The present invention relates to an article, especially a cooktop or a furniture element, comprising at least one substrate, such as a plate, made of glass-ceramic, said substrate being coated in at least one zone with a paint comprising at least: 1) a silicone resin comprising methyl and phenyl group(s), 2) a silicone resin comprising methyl group(s) and devoid of phenyl group(s), 3) one or more lamellar inorganic fillers with a thickness of less than 2 ?m and with lateral dimensions, for at least 80% by weight of said fillers, of less than 10 ?m, including talc and/or one or more carbonates, 4) one or more black pigments. The present invention also relates to a process for obtaining said article.
