Abstract
Process for the manufacture of a toughened and/or bent, infrared-reflecting sheet of glass made of sodalime silicate glass, in which on at least side of a transparent glass base a silver coating is applied and on its side facing away from the glass base at least one anti-reflection coating made of metal oxide is applied and a thermal toughening and/or bending process at a temperature of 580.degree. C. to 680.degree. C., preferably 600.degree. C. to 650.degree. C., is carried out, characterised by the fact that a silver coating and an outer coating made of a metal or a metal alloy are applied onto the essentially flat glass base and by the fact that after this the toughening and/or bending process is carried out, in which the outer coating is converted with an increase in volume into an essentially absorption-free metal oxide, forming at least part of the anti-reflection coating, with an index of refraction .gtoreq.1.7, sheet of glass produced according to this and its application.
