    Abstract: This disclosure is directed to a continuous flow ion-exchange system and process (CIOX) in which a fresh molten salt, for example KNO3, is supplied a salt inlet end of a long channeled containment vessel and the used molten salt is removed from a salt outlet end distal from the inlet end of the channel. Glass article is loaded into at least one cassette, the cassette is placed in the vessel containing the molten salt and is translated from the salt outlet end to the salt inlet end. Cassettes containing glass articles are continuously placed into the vessel at the salt outlet lend and are removed as they reach the salt inlet end.

    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.
