Stress imbalances or overtempering may cause spontaneous breakage to occur.
GASP instruments confirm full tempering by providing a measurement of surface compression within the glass, which is correlated to mechanical strength. GASP polarimeters are also used in safety glass applications to optimize furnace settings and to ensure proper fragmentation characteristics.
