Abstract: A chemically prestressed or chemically prestressable, plate-shaped or disc-shaped glass article is provided. The glass article includes a glass with a composition of Al2O3, SiO2, Na2O, and Li2O and a prestressing or a prestressability in relation to the weight percent of Na2O of at least 250 MPa/g Na2O in 100 g of glass. The Na2O is present in a weight percent between at least 0.8 and at most 6.

Abstract: The invention relates to a method for producing a glass substrate for vehicle glazing, in particular for a windscreen of a vehicle, which comprises hot forming of a borosilicate glass, wherein in a hot forming section, at least during stretching of the glass (8) in the flow direction or longitudinal direction of movement of the glass (8), an aging velocity Av of the glass (8) to be hot formed does not exceed 10 mm/s and an aging velocity Av of the glass preferably does not undershoot 3 mm/s, and also relates to glass substrates for vehicle glazing produced by such method as well as to windscreen projection devices and driver assistance systems comprising such glass substrates.
