description 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 SiO2, Al2O3, and Li2O and a content of seed formers (ZrO2, SnO2, and TiO2) 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.
