The invention relates to a ceramic cooktop comprising a cooking plate () made of glass ceramic or glass. The ceramic cooktop also comprises an electrical heat conductor layer () and an insulating layer () that is located between the cooking plate () and the heat conductor layer (). The insulating layer () consists of a plurality of individual layers () that each have a porosity that decreases toward the heat conductor layer ().

Ceramic cooktop

The invention discloses a method of producing a light-scattering layer on a transparent body, in particular consisting of glass or a glass ceramic. The light-scattering layer is produced by thermal spraying a material such as aluminum oxide, titanium oxide etc. onto a surface of the preheated body with a maximum layer thickness of 100 micrometers. The method is particularly suited for preparing light-scattering layers on glass ceramic cooktops.
