Excerpt from Wikipedia:
Tempered glass is a glass in which mechanical stresses are specifically created in the material through heat treatment
and thereby the breaking strength against mechanical or thermal stress is increased.
The finished glass workpiece is heated in an oven and then quickly cooled.
This quenching causes the surface to solidify and the external dimensions of the component now change only comparatively little.
However, the warmer core continues to contract even more strongly because the thermal expansion above the transformation point is significantly higher than below it.
This creates a permanent tension field in the component: a ball is prestressed both radially and tangentially,
A plate is under compressive stress on its surfaces, while a neutral fiber runs in the middle under tensile stress.
This frozen prestress allows the tempered glass to compensate for significantly higher tensile loads than untreated glass.
Since the compressive strength of glass significantly exceeds the tensile strength, this represents an overall improvement.
However, a workpiece treated in this way can no longer be cut in a non-destructive manner, as is possible with untreated glass.
be ground or broken. If the glass breaks, the component breaks into small crumbs.
Tempered glass is used wherever increased mechanical or safety requirements are placed on glass,
for example:
* Window panes on vehicles (car side windows (toughened safety glass), windshields are laminated safety glass)
* Pressure-resistant viewing windows
* Glass furniture
* All glass doors
* Diving masks
* Touchscreens
