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.
