Why do glass stove tops shatter on their own?

Glass cooktops can suddenly shatter during normal use due to sudden thermal shock, intense heat stress, or moving hot cookware between burners. This unexpected failure leaves owners uncertain whether the damage stems from a manufacturer defect or everyday use, complicating warranty claims.
