Patent number: 9156727Abstract: A transparent, dyed cooktop is provided that has improved color display capability. The cooktop is made of a glass ceramic having high quartz mixed crystals as the predominant crystal phase, wherein the glass ceramic comprises none of the chemical refining agents arsenic oxide and/or antimony oxide, except for inevitable trace amounts. The glass ceramic has transmission values of greater than 0.1% in the range of visible light over the entire wavelength range greater than 450 nm, light transmission in the visible range of 0.8 to 5%, and transmission in the infrared at 1600 nm of 45-85%. The glass ceramic also includes a display apparatus that has a display device which is designed to display different operating conditions with different colors and/or symbols.Type: GrantFiled: February 1, 2010Date of Patent: October 13, 2015Assignee: SCHOTT AGInventors: Friedrich Siebers, Thomas Zenker, Helga Goetz, Martin Taplan

Patent number: 8794226Abstract: An oven muffle that has at least two wall elements adjoining each other, which delimit at least some regions of an interior space that is used as a cooking chamber. The wall elements are of a glass or a glass ceramic and the adjacent wall elements are oriented at an angle with respect to one another. In an oven muffle of this invention, along with ease of cleaning, a simple structural design is achieved if the wall elements are integrally joined to one another and constitute one formed part.Type: GrantFiled: May 29, 2009Date of Patent: August 5, 2014Assignee: Schott AGInventors: Wolfgang Schmidbauer, Sascha Backes, Helga Götz, Thomas Zenker, Martin Taplan

Patent number: 6360653Abstract: The wok is made from hardened glass or glass-ceramic material so that it has a cooking surface that is easier to clean than prior art metal woks. Furthermore when it is heated a better temperature distribution for cooking is produced and it can be universally heated, either by a radiantly heated body or an atmospheric gas burner. The method of making the wok starts with a glass blank or piece of borosilicate glass, which is heated until it softens and then is shaped or formed into the shape of the wok, optionally ceramicized and cooled.Type: GrantFiled: February 15, 2000Date of Patent: March 26, 2002Assignee: Schott GlasInventors: Erich Rodek, Helga Goetz, Stefan Hubert, Evelin Weiss, Patrik Schober, Horst Schillert
