Toughened glass is physically as well as thermally solid, and research shows that it can withstand surface compression of at least 10,000lbs per square inch, which is why toughened glass is considered to be safety glass. They are also known to be four to five times stronger than annealed glass and three times more potent than heat-strengthened glass. As these glasses are robust, they reduce the risk of damage if they come in contact with a calamity or disaster.
Toughened glass is manufactured when regular glass is exposed to extreme heat and then cooled rapidly. Due to this excessive heating and cooling process, the chemical composition of the glass goes through an alteration making it more resilient.
