Details: Founded in 1939, Duralex has been manufacturing glassware and tabletop products in La Chapelle-Saint-Mesmin, a city in the heart of France. Since 1939, when Duralex invented the glass tempering process, the name Duralex has been associated with resilient glassware, thanks to their proprietary tempering process. The original tempered (toughened) Picardie glasses are still in production in France and are known as the Original French Tumblers. The Picardie glass is the perfect weight: functional yet stylish and feels extremely comfortable in the hand. They are equally suitable for cold or hot drinks, conveniently stackable, impact and chip resistant, microwave and dishwasher safe. With the help of continuous investments and commitment to quality, Duralex has reached a level of excellence that makes its products recognized throughout the world. Duralex is and will always remain a true French manufacturer of glassware and tabletop products, and is the only glass manufacturer that makes 100% of their products in France.
