Zusammenfassung:	A colorless soda-lime glass composition comprising by weight from 68 to 78% SiO2, from 8 to 18% Na2O, from 0 to 10% K2O, from 7 to 12% CaO, from 0 to 10% MgO, from 0 to 10% ZnO, from 0 to 10% BaO, from 0 to 3% Al2O3, from 0 to 1% B2O3, from 0 to 1% SrO, less than 0.078% total sulfur expressed in the form of SO3, at most 0.12% total cerium expressed in the form of CeO2, from 50 to 1200 ppm total iron expressed in the form of Fe2O3, without the intentional addition of Mo, As, Sn and Sb species, and with a redox lower than 45.
