Abstract
A glass has a maximum crystallization rate (KG) of at most 0.20 μm/min in a temperature range of 700° C. to 1250° C. and a hydrolytic stability according to a hydrolytic class 1 HGA1 according to ISO 720:1985. In the case of a sample thickness of 2 mm of the glass, a ratio of a minimum transmittance in a wavelength range of 850 nm to 950 nm to a maximum transmittance in a wavelength range of 250 nm to 700 nm is in a range of 1.9:1 to 15:1.
