Your favorite glass is our bestseller! If that’s not a reason to finally offer the Duralex bistro glass in a set of six (then we don’t know what is). Choose from six sizes. The drinking glass from the famous “Picardie” series is made of tempered glass, recognizable by its relatively thick walls. It’s manufactured using the pressed glass process and owes its stability to the tension created between the glass layers—the outer and inner walls of the vessel—during the manufacturing process. (If it were to shatter, it would break into a thousand small, almost blunt shards that are less likely to cause injury.)

Duralex has been manufacturing everyday glassware made from so-called tempered glass in central France for decades. The process of making glass less susceptible to impact and, at the same time, heat-resistant by alternating between heating—to about 600 °C—and rapid cooling in a cooling oven is now also mastered by others. However, hardly any other glass has achieved such worldwide fame as the bistro glass from the “Picardie” series, which has long been an indispensable fixture (not only) in French pubs.

Tempered glass is considered impact-resistant and shatterproof. Nevertheless, you should handle these drinking glasses with the same care as any other "normal" glass, as tempered glass is under tension so that the vessels are also suitable for hot drinks. Microscopic cracks in the material - caused by knocks or blows, for example during the cleaning process in the dishwasher - or material fatigue due to ageing can cause the stress ratios to become unbalanced and the glass to break.
