When using Pyrex or any glass bakeware or cookware, you should avoid extreme temperature changes—very cold dishes shouldn’t be placed in a hot oven, and vice versa. Exposure to the oven’s heating element could cause damage to your Pyrex, causing it to crack or break.
Is it OK to put cold Pyrex in the oven?
It is considered safe, however, to transfer a Pyrex dish directly from the refrigerator or freezer to a hot oven, provided it has been properly preheated — some ovens use the broiler element to heat up to the desired temperature.
At what temperature does Pyrex break?
Is Pyrex glassware susceptible to shattering? Shattering is relatively rare, but it can happen when glassware is exposed to sudden temperature changes (known as thermal shock), extremely high heat (over 425 degrees), or direct heat.
Why did my Pyrex dish exploded in the oven?
When a Pyrex bowl is heated or cooled rapidly, different parts of the bowl expand or contract by different amounts, causing stress. If the stress is too extreme, the bowl’s structure will fail, causing a spectacular shattering effect.

Can I bake in Pyrex at 450?
Pyrex is meant to be able to withstand higher temperatures. Pyrex can be used safely inside an oven that is less than 450 degrees F. Whether or not it’s inside a conventional oven or a convection oven, this glassware will be safe to use so long as that temperature isn’t exceeded.
Does baking in Pyrex take longer?
You’re right: Pyrex, and other tempered glass, takes longer to heat up and longer to cool down than metal. Because glass is so efficient, you often need to make adjustments in either baking time or temperature, or both, when baking. Otherwise, food tends to get overbaked or over-browned.
What is the highest temp for Pyrex?
The maximum recommended working temperature for PYREX laboratory glassware is approx 500°C (for short periods of time only). PYREX glass also performs well at lower temperatures. This glass can withstand conditions down to -190°C and is suitable for use with liquid nitrogen.

Will a glass pan break in the oven?

Always cover the bottom of the dish with liquid before cooking meat or vegetables.
Can I freeze lasagna in a Pyrex dish?
What I do is assemble the lasagna in a Pyrex dish, cover it with a plastic lid and put it in a freezer. It doesn’t really matter which lasagna recipe you use – all kinds of lasagna freeze well. After you defrost frozen lasagna, you can cook it the same way as you would as if it was never frozen.
How do you stop Pyrex from exploding?
It’s best to put the dish on a dry dish towel or a metal cooling rack to cool. Damp towels or surfaces can also cause the hot glass to shatter. Don’t use tempered-glass bakeware on the stovetop, under the broiler, in a toaster oven, or on a grill.
