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.
