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 () in the flow direction or longitudinal direction of movement of the glass (), an aging velocity Av of the glass () 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.

Glass substrate for vehicle glazing, in particular for the windscreen of a vehicle

A hot-formed, chemically prestressable glass article having a low percentage of crystals or crystallites, in particular a plate-shaped, chemically prestressable glass article, as well as to a method and a device for its production are provided. The glass article has a composition including the components SiO, AlO, and LiO and a content of seed formers (ZrO, SnO, and TiO) of at least 0.8 wt %, as well as at most ten crystals, including crystallites, per kilogram of glass, which have a maximum diameter greater than 1 μm and up to at most 5 μm.
