Abstract: A glass ceramic article is provided so that a reliable coloring with a defined transmittance is ensured. The reliable coloring of the glass ceramic article is based on a high content of iron oxide of more than 0.1 percent by weight which itself has a strongly coloring effect does not further reduce transmittance but rather interacts with vanadium oxide to attenuate the absorption caused by vanadium oxide.

Abstract: A product is provided that includes a volume-colored monolithic glass or glass ceramic element and to a method for producing same. The glass or glass ceramic element has a first region in which the coloration is modified so that light transmission of the first region differs from light transmission of a second, adjacent region. The light scattering in the region of modified coloration in the glass or glass ceramic remains the same as light scattering in the second, adjacent region with non-modified light transmission.

Abstract: A cooktop with a graphical display device is provided. The cooktop includes a glass ceramic substrate with a dead-front effect in which lightness differences in the display area and in particular differences between the latter and the adjacent areas of the cooktop are not visible for a user from the exterior. The cooktop has a glass or glass ceramic substrate and a display device with a display surface for displaying information by emission of light, wherein the display device is in the interior of the cooktop or cooking appliance such that light emitted from the display surface passes through the glass or glass ceramic substrate and is perceptible by a user in the exterior.

Abstract: A cooktop is provided that has a glass ceramic cooking plate, at least one heater arranged below the glass ceramic cooking plate, and at least one touch sensor. The touch sensor is operable across the glass ceramic cooking plate for adjusting the power of the at least one heater. The glass ceramic cooking plate has an increased strength and is therefore produced with a reduced thickness, whereby the sensitivity and reliability of the touch sensor is significantly improved.

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.
