Beschreibung
Zusammenfassung:	A glass includes the following components in the specified proportions (in % by weight): 50-80% SiO2, 2-30% B2O3, 0-5% Al2O3, 0-10% CaO, 0-10% BaO, 0-5% Li2O, 0-20% Na2O, 1-25% K2O, and 5-30% ΣR2O. R2O includes at least one alkali metal oxide. The glass includes at least one first solarization component and at least one second solarization component. A proportion of the first solarization component in the glass is in a range from 0.01 to
