    Abstract: The embodiments described herein relate to chemically and mechanically durable glass compositions and glass articles formed from the same. In another embodiment, a glass composition may include from about 70 mol.% to about 80 mol.% SiO2; from about 3 mol.% to about 13 mol.% alkaline earth oxide; X mol.% Al2O3; and Y mol.% alkali oxide. The alkali oxide may include Na2O in an amount greater than about 8 mol.%. A ratio of Y:X may be greater than 1 and the glass composition may be free of boron and compounds of boron. In some embodiments, the glass composition may also be free of phosphorous and compounds of phosphorous. Glass articles formed from the glass composition may have at least a class S3 acid resistance according to DIN 12116, at least a class A2 base resistance according to ISO 695, and a type HGA1 hydrolytic resistance according to ISO 720.

    Abstract: According to one embodiment, a glass article may include a glass body having a first surface and a second surface opposite the first surface. The first surface and the second surface each have a radius of curvature. The first surface of the glass body comprises a flaw population extending from the first surface into a thickness of the glass body with a maximum initial flaw depth Ai. The first surface of the glass body may be etched to a depth less than or equal to about 25% of the maximum initial flaw depth Ai of the flaw population present in the first surface. When the glass article is under uniaxial compressive loading, at least a portion of the first surface is in tension and a uniaxial compressive strength of the glass article is greater than or equal to 90% of a uniaxial compressive strength of a flaw-free glass article.
