    Abstract: A thermally tempered glass element is provided made of glass with two opposite faces that are under compressive stress of at least 40 MPa. The glass has a working point at which the glass has a viscosity of 104 dPa·s of at most 1350° C. The glass has a viscosity versus temperature profile and a coefficient of thermal expansion versus temperature profile of the glass are such that a variable (750° C.-T13)/(CTELiq-CTEsSol) has a value of at most 5*106 K2. The CTELiq is a coefficient of linear thermal expansion of the glass above a glass transition temperature Tg, the CTESol is a coefficient of linear thermal expansion of the glass in a temperature range from 20° C. to 300° C., and the T13 is a temperature at which the glass has a viscosity of 1013 dPa·s.

    Abstract: A plate-shaped or disc-shaped, chemically prestressed or chemically prestressable glass article is provided. The article includes a glass with a composition of SiO2, Al2O3, and Li2O; and a set-drop strength of at least 50 and up to 150, given as drop height in cm, wherein the drop height is given as the mean value of 15 samples, with the use of a sandpaper grit of 60. The glass has one or more features including: a CIL of greater than 1 N, 1.2 N, 2N, or 3 N, a DoL of at least 90 μm, 100 μm, 115 μm, or 130 μm, a content of network formers of at least 82 wt. %, and a content of alkali oxides of at most 14 wt. % or 12 wt. %.
