Abstract: A glass exhibiting non-frangible behavior in a region where substantially higher central tension is possible without reaching frangibility is provided. This region allows greater extension of the depth of compression in which fracture-causing flaws are arrested, without rendering the glass frangible despite the presence of high central tension region in the sample.

Abstract: Methods for reducing a defective area in a strengthened substrate to produce a non-defective substrate are provided. The methods include contacting a strengthened defective substrate with a heated salt bath containing at least one monovalent salt, and removing the strengthened substrate from the bath. The strengthened substrate, before being contacted with the salt bath, is a defective substrate having at least one defective area and one or more non-defective area. Upon removal from the salt bath, at least one defective area has been reduced or substantially removed to produce a non-defective substrate.
