Duralex Gigogne Tumbler 22 cl

France in 1945 was in the midst of reconstruction. Christian Dior shortened skirts and created the New Look, while Saint-Gobain created "tempered glass", an entirely new process that made glass unbreakable. To support this discovery, which marked a new era in the history of tableware, he created the DURALEX brand.

DURALEX is a "tough cookie": its tumblers wobble on every canteen cart in France, but never break. DURALEX is flexible: it will fit into every household, its products stack up, its ranges follow one another, its decorations follow fashion, its prices are accessible.

WHAT IS TEMPERED GLASS?
What makes Duralex glass so resistant is the tempering process. This consists in cooling the entire glass product by ventilation, after it has been heated to a temperature of around 700°C. This treatment creates controlled stresses in the glass that enhance most of its physical qualities: resistance to mechanical stress and thermal shock (sudden temperature change). This makes Duralex glass at least 2.5 times more resistant to mechanical stress than annealed glass. It can withstand a thermal shock of at least 130°C.
