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..

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.
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.
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.
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.
Is Pyrex heat resistant?
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. Pyrex is borosilicate glass which makes it highly temperature resistant. Soda-Lime glass is less suitable for direct heating, so choose Pyrex where possible if you will be applying heat.
How can you tell if glass is heat resistant?
Because tempered glass has characteristics that are so different from annealed glass, manufacturers are required to identify it with a stamp in at least one of the corners. The stamp, which may say “Tempered” or simply “Temp,” is either sandblasted into the glass or applied as a porcelain overlay.
What type of glass is oven safe?
Containers or baking dishes made from tempered glass are heavy, durable, and oven-safe to at least 400 degrees Fahrenheit. They also have a slightly better thermal shock resistance.
Can I bake in a Pyrex Tupperware? PYREX® Glassware can be used for cooking, baking, warming, and reheating food in microwave ovens and preheated conventional or convection ovens. PYREX® glassware is dishwasher safe. This product is intended for normal household use only. AVOID SUDDEN TEMPERATURE CHANGES.
What is highest temp for Pyrex?
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 glass explode?
Pyrex is not resistant to thermal shock, therefore, there are instances where Pyrex glassware can explode when it is moved from a hot environment to a cold one and vice versa. In short, avoid exposing your Pyrex to extreme temperature changes at all times.
Can you heat Pyrex to 500?
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. Pyrex is borosilicate glass which makes it highly temperature resistant.
Is it safe 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.
When did Corning stop making Pyrex?
In 1998 however, due to slumping sales and retooling of manufacturing plants, Corning sold off the CorningWare and Pyrex lines to World Kitchen, LLC.
At what temperature will Pyrex shatter? 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.
Can Pyrex stand 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 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.
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.
Is all glass oven-safe?
The answer is, you can put glass in the oven, microwave oven or toaster oven if it’s oven-safe-glass. It would be risky to put any glass in the oven without checking this simple but vital aspect of glass, so it’s best to look for an oven-safe label on your container before using it.
What temp does Pyrex glass melt?
| Wavelength (nm) | Refractive Index |
|---|---|
| Softening Point (°C) | 820 |
| Annealing Point (°C) | 565 |
| Melting Point (°C) | 1250 |

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 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 temp 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.
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 you bake in vintage Pyrex? That means that if you have Pyrex glassware made before 1998 (like this gorgeous vintage design), you can safely use it like you always have—making a baked mac n’ cheese casserole and leaving the dish on your cold granite countertop or immediately transferring it to the fridge for tomorrow’s dinner.
