Abstract
A method for visual marking of heat-treated substrates, in particular tempered glass panes. The method modifies a marking layer deposited on a surface of the substrate, that visually indicates that the heat treatment has been carried out, and produces a rough marking field on the surface of the substrate that the marking layer deposited on the substrate exhibits intimate adhesive bonding thereto, which marking layer cannot be completely removed using a mechanical mechanism.
