Although popular wisdom states that pyrex should be used between 425°F and 450°F at most, there is an alternative temperature set of temperature limits you could go off of. A Pyrex glass pan could, in theory, endure temperatures of up to roughly 932°F (or 500°C)..

Can Pyrex go in the oven on broil?
Oven-safe glass baking dishes such as Pyrex are not safe to use when broiling. Most of these are not safe to use on the stove. For more information on the use of glass cookware, call the Corning/Pyrex/Revere toll free hotline at 800-999-3436.
What would cause a Pyrex dish to explode 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.
Why did my Pyrex dish explode?
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 Pyrex go in a 450 degree oven?
Pyrex is meant to be able to withstand higher temperatures. But everything has its limitations. 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.
Can you put a cold glass baking dish in the oven?
It would almost certainly be OK, but to be on the safe side I’d put it on a room temperature baking sheet (ideally quite a thick one) before putting it in the oven. This will avoid the thermal stress caused by the bars of the shelf.
What temp does Pyrex glass melt?
| Wavelength (nm) | Refractive Index |
|---|---|
| Softening Point (°C) | 820 |
| Annealing Point (°C) | 565 |
| Melting Point (°C) | 1250 |

Will Pyrex crack from cold to hot?
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. Sudden changes in temperature may cause the dishes to shatter or break.
What does JAJ Pyrex mean? JAJ (short for James A Jobling) were the producers of PYREX tableware, casserole dishes and other bakeware in the United Kingdom from 1922 until the plant (in Sunderland, England) closed in 2007.
Can I put glass Pyrex in the oven at 400?
Pyrex can go in a 400-degree oven, provided it’s an oven-safe dish and you’ve taken certain precautions to minimize the chance that thermal shock occurs.
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.
Can you put Pyrex in 425 degree oven?
Pyrex cookware is meant to withstand baking, but it cannot be trusted for use over 425 degrees. This means that for recipes requiring higher temps you should use metal pans.
Can Pyrex withstand 500 degrees?
A: Pyrex is suitable for use from -192°C to +500°C. This makes it an ideal choice for lab glassware which will be directly heated.
Will Pyrex crack from hot to cold?
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. Sudden changes in temperature may cause the dishes to shatter or break.
What temperature does glass break in the oven? Glass is a poor thermal conductor and rapid changes in temperature (roughly 60°F and greater) may create stress fractures in the glass that may eventually crack. When heated, thin glass begins to crack and typically breaks at 302–392°F.
Can Pyrex go from freezer to hot oven? Pyrex is safe for storage in the freezer, and the Pyrex website states that the glassware can go directly from the freezer and to an oven temperature of around 300 degrees.
Can you bake Pyrex at 450?
Pyrex is meant to be able to withstand higher temperatures. But everything has its limitations. 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.
Is there a difference between Pyrex and Pyrex?
Products with the name ‘pyrex’ (all lowercase) are made by a company called World Kitchen and are made out of clear tempered high-thermal-expansion soda-lime glass, which has a lower thermal shock resistance, making them susceptible to explosions in the microwave or oven.
Is it OK to put a cold glass dish in the oven?
It would almost certainly be OK, but to be on the safe side I’d put it on a room temperature baking sheet (ideally quite a thick one) before putting it in the oven. This will avoid the thermal stress caused by the bars of the shelf.
Is vintage Pyrex safe to use?
Is vintage Pyrex safe to use? The short answer to this is “I wouldn’t use it.” This was a common response to the test posted on Facebook. People insisted that since food doesn’t come in contact with the outside of the bowls, these tests do nothing more than drum up fear.
How can you tell if glass is Pyrex?
Use the glass markings, stamps, and logos on the pieces themselves to identify when the glass was produced. The oldest Pyrex markings should be on the bottom of glass pieces and feature Pyrex in all capital letters inside a circle with CG for Corning Glassworks.
Can Pyrex go in a 400 degree oven?
Pyrex can go in a 400-degree oven, provided it’s an oven-safe dish and you’ve taken certain precautions to minimize the chance that thermal shock occurs.
Why did my glass dish explode in the oven?
When glass goes rapidly from something cold to hot (like a freezer to an oven) or vice versa, it can experience “thermal shock.” Different sections of a piece of bakeware can expand or contract differently and cause it to lose its structure, resulting in a shattering effect.
What makes Pyrex different from glass? The tempering process when applied to the finished glass products called Pyrex makes it four to six times stronger than the regular glass product. The heat resistant quality to bear up to 425 degrees F makes the Pyrex products ideal for the use in the kitchen especially for cooking or baking purposes.
