Abstract: A glass container comprises a glass body comprising a first region under a compressive stress extending from a surface of the glass body to a depth of compression and a second region extending from the depth of compression into a thickness of the glass body, the second region being under a tensile stress. The glass container also includes a localized compressive stress region having a localized compressive stress extending from the surface to a localized depth of compression within the body. The localized depth of compression is greater than the depth of compression of the first region. The glass container also includes a crack re-direction region extending in a predetermined propagation direction, wherein the crack re-direction region possesses a higher tensile stress than the tensile stress in the second region in a sub-region of the crack re-direction region, the sub-region extending substantially perpendicular to the predetermined propagation direction.

Abstract: Strengthened glass substrates and methods of reducing warp in strengthened glass substrates having 3D and 2.5D shapes are disclosed. In one embodiment, a strengthened glass-based article includes a first surface, a second surface opposite the first surface, and an edge between the first surface and the second surface. The edge is asymmetric with respect to a plane that is located at an average depth of the strengthened glass-based article and is parallel to the first surface and the second surface. The strengthened glass-based article has an expected warp WE based at least in part on a shape of the asymmetric edge of the strengthened glass-based article. An actual warp WA of the strengthened glass-based article is less than 85% of the expected warp metric WE of the strengthened glass-based article. The actual warp WA of the strengthened glass-based article is measured with a concave surface facing up.

Abstract: A tempered glass sheet article includes a glass sheet having a thickness t, at least one edge, and at least one surface. The at least one edge is connected to the at least one surface by an edge-to-surface corner. The edge-to-surface corner is rounded with a radius r and has a surface compression that is at least 78% of a surface compression measured at or near a center of the at least one surface.
