Glass composition, preparation method thereof, and cooking appliance including the same

摘要

Provided are a glass composition, preparation method thereof, and cooking appliance including the glass composition. The glass composition includes a glass frit containing P2O5, a Group I-based oxide, and a Group III-based oxide. The Group I-based oxide is selected from Na2O, K2O, and Li2O, the Group III-based oxide is selected from Al2O3 and B2O3, and the glass frit contains about 40 wt % to about 75 wt % of P2O5.
