At this stage, the internal molecular structure of the glass is altered to prepare it for the next crucial step—rapid cooling.
● Rapid Cooling Techniques
After reaching the desired temperature, the glass is rapidly cooled in a process known as quenching. During quenching, high-pressure air blasts are applied to both surfaces of the glass, causing the outer layers to cool and solidify much faster than the inner layers. This rapid cooling creates a state of tensile stress within the interior and compressive stress on the surface, which significantly enhances the strength and durability of the glass.
● Stress Distribution in Glass
The unique stress distribution in tempered glass is what distinguishes it from regular annealed glass. The compressive stress on the surface and tensile stress in the interior work together to make the glass highly resistant to impact and thermal stress. This engineered stress distribution is the key to the unparalleled performance and safety features of tempered glass.
