ABSTRACT Method for the manufacture of a tempered and/or bent glass pane of soda-lime-silica glass with reduced transmission for solar radiation, in which to at least one side of the transparent glass carrier is applied a metal coating of platinum, iridium or optionally rhodium, alloys of these metals or metal alloys with a preponderant proportion of at least one of these metals in a thickness such that the light permeability of the laminate formed from the glass carrier and the metal coating is between 10 and 90%, particularly between 30 and 90% of that of the glass carrier alone and a tempering and/or bending process is performed in air at a temperature of 580 to 680°c, preferably 600 to 650°C, characterized in that the metal coating is applied to the substantially flat glass carrier before the tempering and/or bending process and on the side of the metal coating remote from the glass carrier an oxide stabilizing coating from or with a preponderant content of at least one metal oxide or mixed metal oxide, preferably from the group Bi, In, Ni, Sb, Sn, Ta, Ti and Zn is applied with a thickness of 2 to 20 nm before the tempering and/or bending process.
