Product Description Duralex Gigogne Tumblers are ideal for modern living, instantly adaptable to any situation;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 even of an impact of accident, shatter into thousands of non-cutting pieces Box Contains 6 x Duralex Gigogne Clear Glass 22cl Tumbler
