Abstract

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.
