摘要：
A method for reducing the defect density of glass comprising melting a glass composition comprising from 65-75 wt. % of SiO2; from 10-20 wt. % of Na2O; from 5-15 wt. % of CaO; from 0-5 wt. % of MgO; from 0-5 wt. % of Al2O3; from 0-5 wt. % of K2O; from 0-2 wt. % Fe2O3; and from 0-2% FeO, wherein the glass composition has a total field strength index of greater than or equal to 1.23 is disclosed.
