Abstract
Embodiments of this disclosuer pertain to glass articles that comprise a maximum CS magnitude (CSmax) of about 900 MPa or greater, a CS magnitude of 750 MPa or greater at a depth of about 5 micrometers, and a maximum CT magnitude (CTmax) disposed at a depth from the first major surface in a range from about 0.25 t to about 0.75 t. Embodiments of a curved glass article are also disclosed. In one or more embodiments, such curved glass articles include the first major concave surface comprising a maximum radius of curvature of about 100 mm or greater and a first maximum CS value (CSmax1) greater than about 800 MPa, a second major convex surface comprising a second maximum CS value (CSmax2), wherein the CSmax2 is less than CSmax1. Embodiments of an automotive interior system including such curved glass articles and methods of making glass articles are also disclosed.
