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
