Furniture giant warns of “table bomb” – Ikea glass suddenly exploded after dishwasher. Tempered glass has a load capacity that is around five times higher than that of non-tempered glass.
Ikea Germany: “Our POKAL glasses are safe to use. Only in rare cases can tempered glass break for no apparent reason.” The company suspects that the glass was already damaged and warns: scratches or a blow could have created tension that caused the glass to shatter.
