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 of mechanical stress (bending, impacts) and thermal shock. 

Duralex glass is 2.5 times stronger than annealed glass and is capable of enduring a thermal shock of 130°C. Our products move smoothly from freezer to microwave.

Specifically designed for cooking in an oven, the OVENCHEF range is made from reinforced tempered glass resistant to a thermal shock of 200°C. Our dishes withstand temperatures between -20°C and 300°C. These products, regrouped under the Ovenware category, are the only Duralex products designed for traditional oven use.

Virtually unbreakable, if however Duralex tempered glass does break in your hands, there is no risk of injury. It bursts into a multitude of blunt pieces, for your safety. This also applies to tempered glass that is used to make windscreens.

To fully enjoy the qualities of your Duralex products and more specifically your Ovenchef baking dishes, kindly abide by the recommendations of use.
