Abstract

Method for the manufacture of a toughened 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 layer of platinum, iridium or optionally rhodium, alloys of these metals or metal alloys with a majority content of at least one of these metals in a thickness such that the light transmittance of the laminate formed from the glass carrier and the metal layer is between 10 and 90%, particularly between 30 and 90% of that of the glass carrier alone and a toughening and/or bending process is performed in air at a temperature of 580.degree. to 680.degree. C., preferably 600.degree. to 650.degree. C., whereby the metal layer is applied to the substantially flat glass carrier before the toughening and/or bending process and on the side of the metal layer remote from the glass carrier an oxide stabilizing layer from or with a majority 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 toughening and/or bending process.
