What is toughened glass?
Toughened glass is created by subjecting the final glass product to a treatment of heating and cooling. The strength of the glass is increased by providing a balance of compressive stresses, as well as tensile stresses in the centre of the sheet of glass. Once completed, the glass is up to five times stronger than regular glass that has the same thickness.
How Toughened Glass Works
The stresses that are highly compressive on the surface provide the increased resistance to both thermal and mechanical stresses. However, the toughened glass is still able to break with extreme loads, or due to severe impact. When the toughened glass is broken, it shatters into very small, blunt edged fragments, which reduces the chance of personal injury.
