GLASS AND METHOD FOR MANUFACTURING GLASS

The present invention addresses the problem of suppressing deflection. The glass 10 contains, in mol% on the basis of oxides, 35%-60% of SiO2, 0.8%-8% of B2O3, 6%-21% of Al2O3, and 17%-44% of MgO, with (MgO/Al2O3) > = 1, the measured Magdrone constant m calculated by formula (1A) is 1.05 or more,...
