Beschreibung
Zusammenfassung:	The present invention relates to a glass article comprising a glass composition, the glass composition comprising: SiO2 in an amount in a range from 65 mol% to 75 mol%; Al2O3 in an amount in a range from 8 mol% to 11 mol%; Na2O in an amount in a range from 14 to 18 mol%; K2O in an amount in a range from 1.75 mol% to 3 mol%; CaO in an amount in a range from 1 mol% to 4 mol%; MgO in an amount in a range from 0 mol% to 3 mol%; ZnO in an amount in a range from 0 mol% to 5 mol%; P2O5 in an amount in a range from 0 mol% to 3 mol%; and wherein the glass article comprises an anneal point temperature and a softening point temperature, and a relationship (annealing point temperature + softening point temperature)/2 is less than 700 °C.
