      What happens if you put glass in the microwave?

      Glass in the microwave can lead to unexpected outcomes. While some types are microwave-safe, others can shatter. When exposed to the oven’s heat, glass, being brittle, can break into sharp pieces, causing potential injuries.

      As it’s heated, the molecules within it move faster, causing pressure to build up. This increases with warmth, reaching its capacity. Consequently, the molecules dissociate from their bonds, enlarge, and violently collide, leading to thermal shock. This chain reaction can result in glass breakage within the microwave, posing risks of injury and damage.

      Microwaving in glass can be a breeze, just ensure it’s the kind that won’t crack under pressure
