Toughened glass, also known as tempered glass, is a type of safety glass that’s been heat-treated to be much stronger than ordinary glass. When it breaks, it shatters into small, less harmful pieces rather than sharp shards.
It’s commonly used in places where safety is a concern, like in glass doors, windows, shower enclosures, and even facades of buildings. You’ll also find it in car windows, furniture, and anywhere you need extra strength and safety.
