The history of "spontaneous breakage" of toughened glass is extensive. With due regard for spontaneity, there is always a mechanical cause. As with other cause-of-failure analyses, the cause can be determined, if ALL of the fragments are preserved.

Common causes include:
Post-manufacture surface damage
Thermal history (improper heat treatment)
Nickel-sulfide inclusions
Improper installation (inadequate edge clearance, for example)
Improper edge finishing
