Patent number: 11724960Abstract: 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).Type: GrantFiled: June 22, 2021Date of Patent: August 15, 2023Assignee: SCHOTT AGInventors: Evelin Weiss, Meike Schneider, Oliver Hochrein, Friedrich Siebers, Roland Dudek, Martin Mueller, Matthias Bockmeyer, Birgit Doerk

Patent number: 11365889Abstract: 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 y 0.27 0.21 0.22 0.25 0.32 0.37 0.45 0.45 0.47 0.34 0.36 ?0.29.Type: GrantFiled: May 2, 2021Date of Patent: June 21, 2022Assignee: SCHOTT AGInventors: Evelin Weiss, Matthias Bockmeyer, Birgit Dörk, Friedrich Siebers, Christian Henn

Patent number: 9701576Abstract: Disclosed are articles that are provided with a haptically-perceptible surface. The articles include a coated glass or glass ceramic substrate which is provided with a layer with haptic properties so that the layer has a haptically perceptible texture. The layer includes texturing inorganic and/or polysiloxane-based particles which are fixed on the substrate by a layer-forming material. The particles cause protrusions on the layer and so produce the haptically perceptible texture.Type: GrantFiled: October 10, 2012Date of Patent: July 11, 2017Assignee: SCHOTT AGInventors: Matthias Bockmeyer, Andrea Anton, Angelina Milanovska, Sven Rebsamen, Birgit Doerk
