Glass processing
Discover the glass tempering process
Tempered glass is created through a heat treatment that strengthens the base sheet, a process known as tempering. This intricate and highly specialized technique requires significant expertise and a deep understanding of the methods involved to achieve optimal results.
The tempering process begins with cutting the glass sheet to the desired dimensions, followed by drilling or countersinking any holes and smoothing the edges. Once the piece is prepared, it is placed on a roller table and moved into a furnace, where it is heated to 640°C. When the glass softens, it is rapidly cooled using jets of cold air. This quick cooling hardens the surface while keeping the center slightly warmer, creating compressive stress on the surface.
This process significantly enhances the strength of the glass, making it about six times more resistant to bending than standard float glass. During tempering, surface defects are effectively “locked in” by the compressive forces, while the interior remains more resistant to cracking. In the event of breakage, tempered glass shatters into small, non-sharp pieces, increasing overall safety.
