In one or more embodiments, the fictive temperature of these glass articles may be equal to the 1011 poise (P) viscosity temperature of the glass article. In some embodiments, the strengthened alkali aluminosilicate glass articles described herein may exhibit a maximum compressive stress of at least about 400 MPa, 800 MPa, 930 MPa or 1050 MPa. In some embodiments, the strengthened alkali aluminosilicate glass articles described herein may exhibit a compressive stress layer extending to a depth of layer of at least about 40 μm (in samples having a thickness of 1 mm). In still other embodiments, these strengthened alkali aluminosilicate glass articles exhibit a parabolic or near-parabolic tensile stress profile in the central region of the glass articles.
