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 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 a flaw population present in the first surface. The flaw population of the first surface is etched to selectively remove material adjacent to each flaw of the flaw population along the maximum initial flaw depth Ai. 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.
