Lys Creuse Plate 23Cm Duralex Du3011A

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.
