When broken, tempered glass shatters into thousands of tiny pebbles, effectively eliminating the risk of human injury from sharp edges.
Tempered glass is a type of soda-lime glass that has been heat-treated to make it more durable. During the heat-tempering process, the exterior of the glass is force-cooled, causing it to solidify quickly while the centre cools more slowly. As the inside of the glass cools, it pulls on the stiff, compressed outer layer, causing tension in the centre.
Tempered glass is also known as safety glass because when it breaks, it breaks into relatively dull cube-shaped pieces rather than long, thin shards. For this reason, tempered glass is also used in passenger car windows and shower doors.
Hence, tempered glass plays an vital role in safety measures.
