The French Duralex Company first began to manufacture glassware in 1927.From 1939 Duralex introduced a tempering and pressing process specially developed by the Saint-Gobain company. The process is based on the principle of thermal shock, with the glass heated to 600∞C then cooled very quickly, giving both excellent transparency and impact resistance of well over twice that of normal glass.
Duralex tempered glassware is equally suitable for cold or hot drinks, conveniently stackable, impact and chip resistant, microwave-proof, and dishwasher-safe.
