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..

Is Pyrex oven safe at 325?
Because of the material makeup of the pyrex glass, it is very safe to bake in it at 350-400 degrees Fahrenheit. In 1988, the pyrex company stopped using borosilicate as their main ingredient. The thermal shock ability of the pyrex glass has come down since then.
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 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 use a Pyrex dish in a convection oven?
These oval baking dishes are great for baking meals in convection ovens, freezing leftovers, and storing cooked food in the refrigerator. All Pyrex products are made in the US, and these glass containers are easy to clean and can withstand temperatures up to 550 degrees Fahrenheit.
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.
Can I 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.
What is the highest temperature for glass bakeware?
How to Minimize the Risks of Glass Bakeware Shattering
- Avoid changes in temperature; no going from freezer to oven, or from oven to sink.
- Do not add liquid to hot glassware.
- No higher heat than 350 F.

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.
Why did my glass pan exploded in the oven?
What Make Glass Shatter? 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.
Why did my Pyrex 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.
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.
How can you tell real Pyrex? 
What is the maximum temperature for Pyrex? A Pyrex glass pan could, in theory, endure temperatures of up to roughly 932°F (or 500°C).
What temperature does Pyrex crack at?
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.
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.
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 would make Pyrex explode in the oven?
According to Pyrex’s safety and usage instructions, “While the glass is designed for temperatures typically used in baking, it can break when exposed to the direct heat element while the oven is preheating.”
How do you stop Pyrex from exploding?
Caption Options
- Don’t set a hot glass dish directly on the metal eyes of your stove.
- Don’t cook a dry dish in a glass pan.
- Ensure all cloths or oven mitts used to handle the pan are dry before using them.
- Use oven mitts to handle hot pans.
- Don’t use glass cookware to reheat dry foods in the microwave.
What temperature can Pyrex glass withstand?
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).
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.
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.
