Abstract: A glass substrate comprises: a first position, wherein a tensile stress of the glass substrate is insufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate; and a second position, wherein the glass substrate is bent relative to the first position, and wherein the tensile stress of the glass substrate is sufficient to cause fragmentation of the glass substrate into small pieces upon fracture of the glass substrate. The glass substrate can include a first surface and a second surface. In the first position, the first surface and the second surface of the glass substrate can be planar. In the second position, the first surface and the second surface of the glass substrate can be planar. The small pieces can be generally cubic. In the second position, the glass substrate can be bent uniaxially along a bend axis of the glass substrate.

Abstract: The disclosure relates to glass compositions with high coefficients of thermal expansion and low fracture toughness designed for thermal tempering. These glasses are ideally suited to produce a “dicing” pattern when thermally tempered, even when thin (<3 mm).

Methods of making such glasses are also provided.
