    Abstract: Embodiments of a glass-based article including a first surface and a second surface opposing the first surface defining a thickness (t) of about 3 millimeters or less (e.g., about 1 millimeter or less), and a stress profile, wherein all points of the stress profile between a thickness range from about 0·t up to 0.3·t and from greater than about 0.7·t up to t, comprise a tangent with a slope having an absolute value greater than about 0.1 MPa/micrometer, are disclosed. In some embodiments, the glass-based article includes a non-zero metal oxide concentration that varies along at least a portion of the thickness (e.g., 0·t to about 0.3·t) and a maximum central tension in the range from about 80 MPa to about 100 MPa. In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a value at a point between the first surface and the second surface and increases from the value to the second surface. The concentration of the metal oxide may be about 0.05 mol % or greater or about 0.5 mol % or greater throughout the thickness. Methods for forming such glass-based articles are also disclosed.

    Abstract: Methods and apparatus provide for: a glass substrate having a first strain to failure characteristic, a first elastic modulus characteristic, and a flexural strength; and a coating applied over the glass substrate to produce a composite structure in order to increase a hardness thereof, where the coating has a second strain to failure characteristic and a second elastic modulus characteristic, where the first strain to failure characteristic is higher than the second strain to failure characteristic, and one of: (i) the first elastic modulus characteristic is above a minimum predetermined threshold such that any reduction of the flexural strength of the glass substrate resulting from application of the coating is mitigated; and (ii) the first elastic modulus characteristic is below a maximum predetermined threshold such that any reduction of the strain to failure of the glass substrate resulting from application of the coating is mitigated.
