    Abstract: A method of forming a glass container including forming a glass container having a sidewall at least partially enclosing an interior volume, at least a portion of an interior surface of the sidewall having an interior surface layer; and contacting the glass container with a substantially fluoride-free aqueous treating medium to remove a thin layer of the interior surface layer having a thickness of from about 100 nm to about 1.0 μm from the interior surface of the sidewall. The interior surface is resistant to delamination. Before contacting the glass container with the substantially fluoride-free aqueous treating medium, the exterior surface of the sidewall comprises strength-limiting surface flaws having a first shape, and after the contacting the exterior surface of the sidewall with the substantially fluoride-free aqueous treating medium, the strength-limiting surface flaws have a second shape.

    Abstract: Glasses with compressive stress profiles that allow higher surface compression and deeper depth of layer (DOL) than is allowable in glasses with stress profiles that follow the complementary error function at a given level of stored tension. In some instances, a buried layer or local maximum of increased compression, which can alter the direction of cracking systems, is present within the depth of layer. Theses compressive stress profiles are achieved by a three step process that includes a first ion exchange step to create compressive stress and depth of layer that follows the complimentary error function, a heat treatment at a temperature below the strain point of the glass to partially relax the stresses in the glass and diffuse larger alkali ions to a greater depth, and a re-ion-exchange at short times to re-establish high compressive stress at the surface.

    Abstract: Ion exchangeable glasses having coefficients of thermal expansion (CTE) at least about 90×10−7 ° C.−1. The glasses undergo rapid ion exchange, for example, in a molten KNO3 salt bath to a depth of layer of greater than 30 microns in less than 2 hours at temperatures of 370° C. to 390° C. When ion-exchanged to a depth of layer between 30 to 50 microns, the glasses exhibit a Vickers median/radial crack initiation threshold exceeding 30 kilograms force (kgf). The glasses are fusion formable and, in some embodiments, compatible with zircon.

    Abstract: A method of manufacturing a strengthened glass article comprises soaking a glass article in a bath comprising molten salt. The molten salt comprises alkali metal ions. During the soaking, the alkali metal ions of the salt are exchanged for smaller alkali metal ions of glass of the glass article and impart a compressive stress in the glass article in an ion-exchanged portion thereof at or near a surface thereof. The glass of the glass article has a strain point temperature of at least 625° C., corresponding to glass viscosity of 1014.68 poise. The temperature of the bath is at least 70° C. below the strain point temperature of the glass of the glass article.
