摘要：
Described is an alkali-free aluminoborosilicate glass with a viscosity of 10.sup.13 dPas at a temperature of above 700.degree.0 C., a processing temperature V.sub.A of less than 1220.degree.0 C., and very good chemical stability, which can be produced in a float unit and has the following composition, in % by weight based on oxide:______________________________________SiO.sub.2 48 -- 20 -- 26MgO 0 -- 8CaO 4 -- 12BaO 0 -- 2SrO 0 -- 2ZnO 1 -- 8ZrO.sub.2 0 -- 2SnO.sub.2 0.5 -- 2______________________________________The glass is especially suitable for use in display technology.
