Did You Know?
1. Pyrex bowls are made from a type of glass called borosilicate, which is known for its resistance to thermal shock. This means that Pyrex bowls can withstand sudden temperature changes, making them oven-safe.
2. Pyrex was originally developed by a German glassware company in the early 1900s, and production was later moved to the United States during World War I due to a lack of raw materials in Germany.
3. While most Pyrex bowls are oven-safe, it is important to note that Pyrex lids should not be placed in the oven. The lids are usually made of a different material, such as plastic, which may not withstand high temperatures.
4. Although Pyrex bowls are generally safe for oven use, it is recommended to avoid placing them directly on a hot stovetop or exposing them to open flames. Direct exposure to high heat sources can cause uneven heating and potential breakage.
5. The Pyrex brand has expanded beyond their iconic clear glass bowls over the years. They now offer a wide variety of kitchenware, including colored glass dishes, ceramic bakeware, and even non-glass cookware like stainless steel and cast-iron pans.
1. Pyrex And Its Thermal Shock Resistance
Pyrex, a well-known brand of glass cookware, has been a staple in kitchens since its introduction in 1915. One of the defining features of Pyrex is its use of borosilicate glass, which gives it thermal shock resistance. This means that Pyrex can withstand sudden changes in temperature without shattering or breaking.
The thermal shock resistance of Pyrex is what makes it ideal for oven use. Whether you’re cooking, baking, warming, or reheating food, Pyrex can handle the heat. However, it’s important to note that direct contact with heating elements can cause the glass to shatter or break. It’s essential to follow the manufacturer’s guidelines and avoid using Pyrex under the broiler or in a toaster oven.
2. Oven-Safe Pyrex: Temperature Limits And Precautions
When using Pyrex in the oven, it’s essential to keep in mind the temperature limits. Pyrex is oven-safe up to 425 degrees Fahrenheit. Going beyond this temperature can result in glass breakage. So, it’s crucial to be mindful of this limit while cooking or baking at high temperatures.
To ensure even heating and minimize sudden temperature changes, it is recommended to preheat the oven before placing Pyrex dishes inside. This helps distribute the heat evenly. Moreover, it’s important to avoid subjecting Pyrex to direct heat sources such as the stovetop, broiler, toaster oven, or grill.
When using Pyrex in the oven, it is also advisable to add a small amount of liquid to cover the bottom of the dish before cooking items that may release liquid. This step helps prevent thermal shock and ensures even heating. Remember not to add liquid to a hot Pyrex dish as it can compromise its strength and cause breakage.
To summarize, when using Pyrex in the oven:
- Keep temperature below 425 degrees Fahrenheit
- Preheat the oven before placing the dish inside
- Avoid direct heat sources
- Add a small amount of liquid to cover the bottom of the dish before cooking items that release liquid
3. Avoiding Direct Heat And Sudden Temperature Changes
The integrity of Pyrex glassware is highly dependent on proper usage. To prevent damage, it’s essential to avoid direct heat sources and sudden temperature changes. Placing hot Pyrex cookware on a dry cloth, potholder, wooden trivet, or cooling rack allows it to come to room temperature gradually, reducing the risk of breakage.
It’s important to note that uneven heating can cause glass to shatter or break. To ensure proper cooking or baking, it’s recommended to preheat your oven and distribute the heat evenly by placing Pyrex dishes in the center of the oven. These precautions will help maintain the structural integrity of the Pyrex and prevent any accidents in the kitchen.
- Avoid direct heat sources and sudden temperature changes
- Place hot Pyrex cookware on a dry cloth, potholder, wooden trivet, or cooling rack
- Preheat the oven and place Pyrex dishes in the center for even heating.
4. Microwave Safety: Guidelines For Using Pyrex
Pyrex is not only oven-safe but also microwave safe. However, it’s essential to check the manufacturer guidelines for specific products as there may be variations in their microwave compatibility. Pyrex’s thermal shock resistance makes it suitable for use in the microwave, but certain precautions should be taken.
When using Pyrex in the microwave, it’s crucial to avoid microwaving popcorn or heating foods in browning wrappers. These practices can cause damage to the Pyrex glassware and pose a safety risk. Additionally, when heating oil or butter in the microwave, it’s recommended to heat only for the minimal time required to prevent overheating and potential glass breakage.
5. Important Precautions For Heating In The Microwave
While Pyrex is microwave safe, some precautions should be followed to ensure optimal safety. It’s essential not to heat empty or nearly empty glass containers in the microwave. Without food or liquid to absorb the microwave energy, the glass may overheat and break.
To ensure the longevity and safety of Pyrex in the microwave, it’s crucial to handle it with care. Use microwave-safe covers or lids to prevent spills and explosions. Always follow the manufacturer’s guidelines and avoid exposing Pyrex to sudden temperature changes, which may occur if you remove it from the microwave and place it in a cold environment.
Note: Heating empty or nearly empty glass containers in the microwave can cause them to overheat and break.
- To prevent accidents, use microwave-safe covers or lids to prevent spills and explosions.
- Follow the manufacturer’s guidelines for using Pyrex in the microwave.
- Avoid sudden temperature changes by not removing Pyrex from the microwave and placing it in a cold environment.
In conclusion, Pyrex bowls are oven-safe with a temperature limit of up to 425 degrees Fahrenheit. However, it’s crucial to avoid direct contact with heating elements and to take precautions to prevent sudden temperature changes. Pyrex is an excellent choice for microwave use, but it’s essential to follow the manufacturer guidelines and take additional precautions to ensure safety. By using Pyrex properly and handling it with care, you can enjoy its thermal shock resistance and rely on it for your cooking and baking needs without any worries.

Frequently Asked Questions
How do I know if my Pyrex bowl is oven safe?
To determine if your Pyrex bowl is oven safe, you should refer to the manufacturer’s guidelines. Most Pyrex dishes are designed to withstand high temperatures and can be used in the oven without any issue. However, it is essential to ensure that your oven is preheated and that both the food and Pyrex dish are at room temperature before using it. If you need to cook or bake something above 400°F, it might be wise to choose an alternative type of bakeware to avoid any potential risks.
Which Pyrex is not oven safe?
The pyrex containers that are not oven safe are the ones made of soda-lime glass. These lowercase pyrex containers should not be heated in the oven or microwave. However, the uppercase PYREX cookware made of borosilicate glass is oven safe and can be used in both the microwave and oven.
Can Pyrex withstand 500 degrees?
Pyrex glass products are designed to withstand temperatures up to 500°F (260°C), making them oven safe for most cooking and baking tasks. However, it is usually recommended to use them at temperatures up to 425°F (218°C) to err on the safe side. Although some adventurous individuals have successfully baked pizza on Pyrex glass at higher temperatures or even over an open flame on a stovetop, it is advisable to avoid such extreme conditions to ensure the longevity of the product and prevent any unexpected breakage.
Is all Pyrex oven and microwave safe?
Absolutely! Pyrex is known for its heat resistance properties, particularly borosilicate glass, which is used in Pyrex dishes. This type of glass can withstand high temperatures, making it safe for use in both ovens and microwave ovens.
