Abstract: A lithium aluminum silicate glass ceramic, which, apart from unavoidable impurities, is As2O3-free and Sb2O3-free. The lithium aluminum silicate glass ceramic has keatite as primary crystal phase and a keatite peak temperature TP of the keatite solid solution formation in the range of 980° C. to 1090° C., and the keatite peak temperature TP is determined by dynamic differential calorimetry (DSC) in accordance with DIN 51007:2019-04 at a heating rate of 5 K/min. A ceramization method is also described.

Abstract: 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 −6 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 CIExyY−2° by the following coordinates: White region W1 x

Abstract: A transparent colored glass ceramic, in particular an LAS glass ceramic, suitable for use as a cooking surface is provided. The transparent colored glass ceramic includes high-quartz solid solution (HQ s.s.) as a main crystal phase and exhibits thermal expansion of −1 to +1 ppm/Kin the range from 20° C. to 700° C. The glass ceramic has from 3.0 to 3.6 percent by weight of lithium oxide (Li2O) as constituents and either is colored with 0.003 to 0.05 percent by weight of vanadium oxide (V2O5) or is colored with 0.003 to 0.25 percent by weight of molybdenum oxide (MoO3).

Abstract: A volume-colored monolithic glass ceramic cooking plate is provided. The plate includes a first zone in which the coloration of the glass ceramic differs from that of a second, adjacent zone, so that an absorption coefficient of the first zone is lower than the absorption coefficient of the second, adjacent zone and so that integral light transmission in the visible spectral range is greater in the first zone than the integral light transmission of the second, adjacent zone. The light scattering in the glass ceramic of the first zone differs from light scattering in the glass ceramic of the second zone by not more than 20 percentage points, preferably by not more than 5 percentage points.
