Dyed cooktop made of a glass ceramic having high quartz mixed crystals as the predominant crystal phase, is claimed, where the glass ceramic comprises none of the chemical refining agents of arsenic oxide and/or antimony oxide, except for inevitable trace amounts, and the glass ceramic has a transmission value of greater than 0.1% in a visible light over the entire wavelength of greater than 450 nm, a light transmission in the visible range of 0.8-5% (preferably 0.8-2.5%), and a transmission in an infrared at 1600 nm of 45-85%, and a display apparatus is provided. Dyed cooktop made of a glass ceramic having high quartz mixed crystals as the predominant crystal phase, is claimed, where the glass ceramic comprises none of the chemical refining agents of arsenic oxide and/or antimony oxide, except for inevitable trace amounts, and the glass ceramic has a transmission value of greater than 0.1% in visible light over the entire wavelength of greater than 450 nm, a light transmission in the visible range of 0.8-5% (preferably 0.8-2.5%), and a transmission in an infrared at 1600 nm of 45-85%, and a display apparatus is provided, which has a display device that is designed to display different operating conditions with different colors and/or symbols. An independent claim is included for displaying an operating state of cooktop, comprising displaying the display apparatus of differently predefined operating modes with different colors and/or symbols. |
