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.

Thin glass elements with improved edge strength are providedfrom a sheet glass element that has two opposite parallel faces and an edge connecting the faces. The sheet glass element has a thickness of at most 700 ?m. At least a portion of the edge is defined by an edge surface portion that is convexly curved, so that at least one of the faces merges into the edge surface portion, wherein a curved arc of the edge surface portion has a length that is at least 1/30 of the thickness of the sheet glass element. In the region of the convex curvature, the edge surface portion has indentations in the form of furrows.

A fitout article or article of equipment for a kitchen or laboratory is provided. The article has a lighting and separating element. The separating element in a region of the lighting element has light transmittance of at least 0.1% and less than 12%. The lighting element in the interior emits light that passes through the separating element and to the exterior. The separating element has a glass or glass-ceramic substrate having a CTE of 0 to 6 ppm/K and has a colour locus in the CIELAB colour space with the coordinates L* of 20 to 40, a* of 6 to 6 and b* of 6 to 6. D65 standard illuminant light, after passing through the separating element, is within a white region W1 determined in the chromaticity diagram CIExyY2 by the following coordinates:
