ABSTRACT:
Formed bodies of glass, especially glass panes, are disclosed provided with electrically conductive circuits and with a colored appearance of the circuits upon looking through the glass and a method of their production. A layer of essentially pigments based on inorganic compounds is located between the optionally enamelled formed body of glass and the circuit which layer is connected via adhesive bridges of a vitrifying material to the formed body and to the circuits. The method of production is carried out by the application of a coating material which contains pigments and is free of vitrifying materials onto a formed body and (ii) the application of a conductive paste thereover containing a vitrifying material and (iii) a heat treatment.
