Can You Safely Move Pyrex From The Fridge Straight To The Oven?
By Kalea Martin
The answer to whether your Pyrex can be safely moved from the fridge to the oven or vice versa depends on the material of your dish.
All Pyrex was originally made with borosilicate, but in the 1950s, the company began manufacturing its cookware with soda lime — a cheaper but weaker glass.
After 1998, soda lime became the standard for all Pyrex dishes sold in the U.S., but in Europe, Africa, and the Middle East, the dishes are still made with borosilicate.
If your Pyrex dish is made with borosilicate, it can withstand drastic temperature changes, but Pyrex made with soda-lime will shatter in extremely hot and cold temperatures.
However, even borosilicate's shatter-resistant Pyrex dishes have temperature limitations. The hottest it can be is 392 degrees F, and the coldest is -40 degrees F.
If you want to make sure that your Pyrex is borosilicate, you'll have to buy new, all-caps "PYREX" dishes produced outside the U.S. instead of the American "pyrex."
