THE SECRET OF PYREX® GLASS

THE SECRET OF PYREX® GLASS

Tempered borosilicate glass

Pyrex® glass is unique. It is a tempered borosilicate glass, of superior quality and high resistance to thermal and mechanical shock. It is perfectly suited to extreme temperatures, from -40° to 300°, and has great resistance to thermal shock of up to 220°.

All Pyrex® glass products are safe to use in the oven, freezer and vice versa. They defy all culinary expectations, from preparation to direct serving, including the entire cooking process, storage and reheating.

The recipe for Pyrex® glass

Pyrex® glass is composed of pure sand (80%), soda (4%), alumina (2.5%) and boron (13%). This mixture is melted in a glass furnace at a temperature of approximately 1500°C. It then quickly transforms into a kind of transparent lava which can be quite dazzling - we can only observe it from afar through a special screen which is only used by glassblowers. In the furnace, the material is then "refined" in order to eliminate any CO2 bubbles that are released during melting.
