Duralex Mugs 6 Mugs Versailles transparant 26 cl

The tempering process is what makes Duralex so tough.
Glass that has been heated to around 700˚C is suddenly cooled by cold air ventilation.
This treatment creates controlled stress in the glass which improves most of its physical qualities: resistance to mechanical stress (bending, impacts) and thermal shock.
Duralex glass is 2.5 times more resistant than an annealed glass product and resists to a thermal shock of 130˚C.
It is the same tempered glass used to make windscreens which, in the event of an impact of accident, shatter into thousands of non-cutting pieces Box Contains 6 x Duraelx Versailles Clear Mug 26cl
