Did You Know?
1. Pyrex, a popular brand of heat-resistant glassware, was originally developed in the early 1900s by a German glass company called Corning Glass Works.
2. Did you know that Pyrex glassware is highly resistant to thermal shock? This means it can withstand sudden temperature changes without shattering or cracking, making it safe for use in the oven.
3. Pyrex glassware was initially made from borosilicate glass, which has a low coefficient of thermal expansion, making it extremely resistant to heat. However, in the 1990s, the formula was changed to soda-lime glass, which has a slightly higher thermal expansion rate but is still safe for oven use.
4. One lesser-known fact about Pyrex is that it can also be used in the freezer. The glass containers are designed to withstand cold temperatures, allowing you to safely store and freeze your food.
5. Pyrex glassware can be easily cleaned in the dishwasher, making it a convenient option for many home cooks. However, it’s essential to ensure that the glassware is not placed directly on hot surfaces when taken out of the dishwasher, as this could potentially cause thermal stress and result in breakage.
Thermal Shock Resistance Of Pyrex
Pyrex is a well-known brand of glass cookware that stands out for its exceptional thermal shock resistance. This means that it can endure sudden changes in temperature without the risk of shattering or breaking.
The key to Pyrex’s resilience is the use of borosilicate glass, allowing it to withstand both high and low temperatures without any complications.
This unique property makes Pyrex a reliable choice for a wide range of cooking tasks.
- Pyrex is a popular brand of glass cookware.
- It is known for its exceptional thermal shock resistance.
- Pyrex can handle sudden temperature changes without breaking.
- Made with borosilicate glass, it can withstand high and low temperatures.
Maximum Oven Temperature For Pyrex
When using Pyrex in the oven, it is crucial to be aware of its temperature restrictions. While Pyrex is generally oven-safe, it has a maximum temperature limit. To prevent any mishaps, it is recommended to use Pyrex at temperatures below 425 degrees Fahrenheit (218 degrees Celsius). Going beyond this limit can lead to the glass breaking or shattering, which can be hazardous.
Caution With Heating Elements And Pyrex
Although Pyrex is thermal shock resistant, it is essential to be cautious when using it near direct heating elements. Direct contact with heating elements, such as an open flame or electric coil, can cause Pyrex to break. Therefore, it is crucial to keep the glass cookware away from broilers, toaster ovens, and grills. Additionally, it is important to preheat the oven before putting Pyrex inside to avoid sudden temperature changes that could potentially cause the glass to shatter.
Limitations Of Pyrex Usage (Broiling, Toaster Ovens, Grills)
While Pyrex is a versatile cookware option, it has some limitations when it comes to certain cooking methods. It is not recommended to use Pyrex for broiling, toaster ovens, or grills because of the direct and intense heat they generate. The high temperatures and direct exposure to heating elements can exceed the safe limits for Pyrex, resulting in breakage or shattering. It is best to use alternative cookware options specifically designed for these cooking methods.
- Pyrex is versatile but not suitable for broiling, toaster ovens, or grills.
- Direct and intense heat can cause Pyrex to break or shatter.
- Alternative cookware options are available for these specific cooking methods.

Precautions For Handling Pyrex Dishes
To ensure safety when using Pyrex, it is crucial to follow these precautions:
- Avoid handling Pyrex dishes with wet oven mitts or potholders, as this can quickly transfer heat and cause burns or dropping the dish.
- Do not place Pyrex directly on stovetops or broilers, as the direct heat source can cause the glass to break.
- To prevent uneven heating, it is recommended to add a small amount of liquid to cover the bottom of the Pyrex dish when cooking foods that release liquid. However, be cautious, as adding liquid to hot Pyrex dishes can lead to breakage.
- Pyrex dishes with plastic lids should not be put in the oven, as the plastic may melt or warp. Silicone and glass lids are usually oven-safe for Pyrex dishes and can be used appropriately.
- Avoid using Pyrex for microwaving popcorn or heating foods in browning wrappers, as these materials can cause excessive heat build-up and potentially damage the glass.
- Do not microwave empty or mostly empty Pyrex dishes, as the absence of contents can cause heat concentration and lead to breakage.
For cleaning Pyrex:
- It is usually safe to use a dishwasher, but ensure that the Pyrex does not come into contact with the dishwasher’s heating element to prevent thermal shock and breakage.
- Avoid sudden temperature changes when using Pyrex in the oven. For example, taking Pyrex directly from the freezer to the oven can cause the glass to crack due to the extreme temperature difference.
- When removing hot Pyrex from the oven, place it on a dry countertop using trivets or dry kitchen towels. Placing it on a wet countertop can cause thermal shock and potentially break the glass.
- It is recommended to allow Pyrex to cool down to room temperature before exposing it to a different temperature, such as putting it in the refrigerator.
In conclusion, Pyrex is indeed oven safe thanks to its thermal shock resistance. However, it is essential to adhere to certain guidelines to ensure its safe and proper use. By understanding the maximum oven temperature for Pyrex, avoiding direct contact with heating elements, and taking precautions when handling the dishes, you can fully enjoy the benefits of this reliable and versatile glass cookware.

Frequently Asked Questions
How do I know if my Pyrex dish is oven safe?
To determine if your Pyrex dish is oven safe, you can begin by checking the manufacturer’s guidelines. Pyrex claims that its products are designed to withstand high temperatures called for in baking recipes, as long as the dish is preheated along with the oven and the food and dish are at room temperature. However, for added precaution, if you plan to cook or bake something exceeding 400°F, it might be advisable to opt for an alternative type of bakeware.
Can Pyrex be put in the oven?
Absolutely! Pyrex is specifically designed to handle high oven temperatures and is safe to use in both conventional and convection ovens. Whether you want to bake your favorite pie, roast vegetables, or reheat leftovers, Pyrex glass cookware is your go-to option. Its heat resistance allows for worry-free cooking, making it a versatile and convenient choice for all your oven needs.
Which Pyrex is not oven safe?
The pyrex containers with lowercase letters are not oven safe. These containers are typically made of soda-lime glass and are not designed to withstand high oven temperatures. If you want to heat your food in the oven or microwave, it is important to use the PYREX cookware with uppercase letters, which is made of borosilicate glass and can safely handle the heat without any concerns.
Can Pyrex withstand 500 degrees?
Pyrex glass products are designed to withstand temperatures up to 500°F (260°C), making them ideal for most oven baking needs. However, it is advisable to use them at temperatures up to 425°F (218°C) to ensure maximum safety. While there have been cases of successfully baking a pizza on Pyrex glass at 600°F (315°C) or even over an open flame on a stovetop, it is best to avoid subjecting the glass to these extreme conditions to prevent any potential damage or accidents.
