Abstract
Process for the manufacture of a toughened and/or bent sheet of soda-lime silica glass with reduced transmission, in particular a solar control glass sheet, wherein at least one transmission-reducing coating having a considerable content of a metal or a metal alloy from the elements with atomic numbers 22 to 28 in the periodic table is applied in such a thickness on at least one side of a transparent glass base that the light transmission of the glass carrier provided with the transmission-reducing coating is between 10 and 90% of that of the glass base alone, and a thermal toughening and/or bending process is carried out in air at a temperature of 580.degree. C. to 680.degree. C., preferably 600.degree. C. to 650.degree. C., whereby the transmission-reducing coating is produced by magnetron cathode sputtering before the thermal toughening and/or bending process means of the joint application of the metal or metal alloy from the elements with atomic numbers 22 to 28 and of silicon as a metal silicide coating with a silicon content of at least 45 atom %.
