Q & A: Curved Tempered Glass – Properties, Applications & Comparisons

Can curved glass be tempered?

Yes, curved glass can be tempered, and this process significantly enhances its structural integrity and safety. The tempering procedure involves heating the glass to approximately 620°C (1148°F), shaping it over a mold to achieve the desired curvature while still malleable, and then rapidly cooling it through a process called quenching. This rapid cooling creates compressive stresses on the surface and tensile stresses in the interior, resulting in glass that is up to five times stronger than standard annealed glass.

This enhanced strength makes tempered curved glass highly resistant to thermal stress, mechanical impact, and sudden temperature changes. It is widely used in architectural and automotive applications where durability and safety are paramount. Importantly, the curving must occur during the heating phase—before tempering—as attempting to bend glass after tempering would cause it to shatter.
