Abstract: A glass article (and methods for forming the same) includes a glass body having first and second opposing primary surfaces and a thickness defined between the primary surfaces. The glass body includes a compressive stress region that includes: a surface stress of greater than about 900 MPa (compressive), a spike region having a first slope, and a tail region having a second slope. The spike region and the tail region can intersect at a knee region having a stress of greater than about 35 MPa (compressive), wherein the stress at the knee region is defined as the point where the asymptotic extrapolation of the spike region and the tail region intersect. The first slope of the spike region can be steeper than about −30 MPa/μm.

Abstract: A glass article is provided that includes: a glass substrate comprising a thickness and a primary surface; and a textured region defined by the primary surface. The textured region comprises a plurality of sub-surface hillocks, each hillock having a top surface and a base, the base located below the primary surface of the substrate. The plurality of hillocks comprises an average lateral feature size from 0.1 μm to 3 μm and an average height from 5 nm to 200 nm. Further, the primary surface of the substrate is substantially planar.

Abstract: A glass-based article with a textured surface exhibiting low haze is provided. The glass-based articles are produced by utilizing a combination of abrasion and etching, where hydrofluoric acid is not utilized. The process for producing the glass-based articles also includes an ion exchange process.

Abstract: Glass-based articles comprise stress profiles providing improved scratch resistance. The glass-based articles comprise: a thickness t; a lithium aluminosilicate composition; and a molar ratio of sodium oxide (Na2O) to lithium oxide (Li2O) that is less than or equal to 0.63 at the center of the glass-based article. The articles have a molar ratio of sodium dioxide (Na2O) to lithium dioxide (Li2O) in a post-spike near region that is greater than or equal to 0.9 and/or less than 1.5.
