The Pyrex® glass is unique. It is a borosilicate glass that is tempered, of superior quality and has a great thermal and mechanical shock resistance. It is perfectly adapted to extreme temperatures, from –40° to 300°, and has a high thermal shock resistance that can go up to 220°.
All the Pyrex® glass products can be used safely in the oven and freezer and the other way around. It defies all culinary expectations, from prepping to serving directly, by going through a whole cooking process, to storing and reheating.
