  • Patent number: 7380415
    Abstract: The glass ceramic panels are non-transparent and have at least one decoration. In order to fulfill the requirements for a glass ceramic panel that provides a cooking surface for a cooking unit in a variety of different pleasing colors, especially a creamy white color shade (BISQUE), in an economical manner, the glass ceramic panel has a predominant crystalline phase of keatite mixed crystals and a full-surface decorative coating that covers at least 80 percent of the upper smooth surface of the glass ceramic substrate. The full-surface decorative coating is provided in a different color from,the glass ceramic panel. Methods for making these glass ceramic panels are described.

  • Patent number: 6914223
    Abstract: The cook top is divided into at least one cold zone and cooking zones heatable by radiant heating elements under the cooking zones. The cook top includes a transparent, colorless glass ceramic or glass plate and a non-ceramic underside layer or layers on the underside of the plate. The upper side of the glass ceramic or glass plate is free of any decoration or layer, thus providing a cooking surface having improved smoothness for easy cleaning. The non-ceramic underside layer is permeable to infrared radiation in the cooking zones and is a color-imparting decoration. The underside layer, at least in cooking zones, has transmission properties for visible light such that the radiant heating elements are not visible from above, at least when they are not in a switched-on state.

  • Publication number: 20030019864
    Abstract: Modern cook-tops typically comprise a colored glass ceramic plate (1) serving as a cooking surface, which has cooking zones (2) that are heated by radiant heating elements (3), and on whose top side decorations are applied. In order to obtain particularly brilliant decorations while providing a smooth cooking surface of the glass ceramic plate (1), said glass ceramic plate (1) is comprised of a non-colored transparent glass ceramic material, whereby the decorations consisting of temperature-resistant coloring substances are applied as IR-permeable coatings (6) only to the underside of the glass ceramic plate (1). The decorations, when viewed from above, thus display brilliant shapes like a rear surface glass painting, and the cooking surface side of the glass ceramic plate (1) remains smooth.
