Did You Know?

1. Contrary to popular belief, not all Pyrex glassware is oven-safe. The original Pyrex borosilicate glass was designed to withstand high heat, but after the company was sold, they switched to a less heat-resistant soda-lime glass in the United States. So, newer Pyrex products may not be suitable for the oven.

2. Did you know that vintage Pyrex dishes can be worth a lot of money to collectors? Some rare and original Pyrex pieces, particularly those with unique patterns or shapes, can fetch hundreds or even thousands of dollars at auctions and online marketplaces.

3. Pyrex glass can actually explode if it experiences rapid temperature changes. This phenomenon, known as thermal shock, occurs when the glass is exposed to extreme temperature variations too quickly. To prevent this, it’s important to gradually heat or cool Pyrex dishes to avoid drastic temperature swings.

4. Pyrex was initially developed in the early 20th century for use in scientific laboratories. Its heat-resistant properties and ability to withstand thermal shock made it a popular choice among scientists and chemists for conducting experiments and storing chemicals safely.

5. In 1915, Pyrex introduced its first consumer product: a clear glass measuring cup. This innovation revolutionized the kitchen by providing a reliable way to measure ingredients accurately. The Pyrex measuring cup quickly gained popularity and became a staple in households around the world.

Oven Safety of Pyrex Glass Bakeware and Cookware

Pyrex is a well-known and trusted brand for glass cookware and bakeware. One frequently asked question is whether Pyrex can be used in the oven. The answer is yes, but there are important considerations to keep in mind. Pyrex glass bakeware, such as pie plates, mixing bowls, measuring cups, custard cups, and food storage containers, is oven-safe up to 425°F.

The key feature that makes Pyrex glassware oven-safe is its ability to withstand high temperatures without shattering or warping. To ensure safety and durability, Pyrex glassware is etched with “PREHEATED OVEN ONLY” on the bottom. This serves as a reminder that it should only be used in a preheated oven and not directly on a stovetop or under the broiler. Using Pyrex glass bakeware in these ways can cause thermal shock and lead to breakage.

Distinctions Between Oven-Safe Pyrex Glass and Non-Safe Plastic Lids

Pyrex glass lids are oven-safe up to 425°F, making them suitable for use during baking or roasting. However, it is crucial to note that Pyrex plastic lids are not oven-safe and will melt if exposed to high temperatures. Therefore, never put Pyrex plastic lids in the oven. Instead, use them for storage or for covering your Pyrex glassware after it has cooled down.

Precautions for Using Pyrex Glassware in the Oven

When using Pyrex glassware in the oven, precautions must be taken to avoid thermal shock and extend its lifespan. Follow these tips to ensure the safety and longevity of your Pyrex glassware:

  1. Preheat the oven: Before placing Pyrex glassware in the oven, preheat it and allow it to reach the desired temperature. This helps prevent sudden temperature changes that can cause the glass to shatter.

  2. Create a protective barrier: To further prevent thermal shock, pour a small amount of liquid (e.g., water or oil) into the bottom of the Pyrex glassware before adding any food. This creates a barrier that protects the glass and helps evenly distribute heat.

  3. Handle with care: When removing Pyrex glassware from the oven, always use potholders and both hands. This helps prevent burns and ensures a secure grip.

Remember to follow these guidelines to safely use Pyrex glassware in the oven and avoid any potential damage.

  • Preheat the oven before using Pyrex glassware
  • Pour a small amount of liquid into the glassware before adding food
  • Always use potholders and both hands when handling Pyrex glassware from the oven.

Proper Handling and Cooling of Hot Pyrex Glassware

After removing hot Pyrex glassware from the oven, it is important to handle it with care to avoid thermal shock and potential breakage. To prevent damage, follow these steps:

  1. Place the hot glassware on a padded surface, such as a silicone mat or a folded kitchen towel, to allow it to cool gradually.
  2. Avoid placing hot glassware directly on a cold surface, such as a countertop or sink, as this can cause thermal shock and lead to breakage.

In the unfortunate event that Pyrex glassware does break, it’s crucial to take the following precautions:

  1. Let the glassware cool completely before attempting to clean it up.
  2. Use caution to avoid any injury from sharp glass shards.
  3. To ensure all shards are removed, it is advisable to use a handheld vacuum cleaner instead of a broom or regular vacuum, as the latter may spread the tiny glass fragments.

Remember: handle hot glassware with care and take necessary steps to prevent accidents.

Warranty and Special Care for Pyrex Products

Pyrex is committed to the quality and safety of its products, offering a two-year warranty on glassware specifically for thermal shock and shattering. If your Pyrex glassware breaks during normal use within this timeframe, Pyrex will replace it at no cost. It’s important to remember that this warranty does not cover instances of misuse or accidents.

To prolong the lifespan of your Pyrex glassware, it is crucial to adhere to the manufacturer’s usage guidelines. Avoid subjecting the glassware to sudden temperature changes, such as placing hot items in cold water or moving it from the oven to the freezer. Additionally, it is recommended to refrain from reusing any broken Pyrex glassware, as its structural integrity may have been compromised.

In terms of temperature resistance, Pyrex glass bakeware and cookware can safely withstand oven heat up to 425°F. Nonetheless, it is of utmost importance to follow the provided safety instructions, including preheating the oven, using potholders, and taking measures to prevent thermal shock. By following these recommendations and properly caring for your Pyrex glassware, you can confidently rely on its durability and dependability for your kitchen endeavors.

Frequently Asked Questions

How do I know if my Pyrex dish is oven safe?

To be sure if your Pyrex dish is oven safe, it is important to read the specific instructions provided by the manufacturer. While Pyrex is generally safe for baking at any temperature mentioned in recipes, it is recommended to take precautions such as pre-heating the oven and ensuring both the food and Pyrex dish are at room temperature. However, for higher temperatures exceeding 400°F, it would be prudent to utilize an alternative type of bakeware to err on the side of caution.

Can a glass Pyrex go in the oven?

Yes, Pyrex glass is indeed oven-safe, with a heat tolerance of up to 425 degrees. However, it is important to avoid direct contact with heating elements as this can lead to the glass shattering or breaking. It is also worth noting that Pyrex is not suitable for use under the broiler or in a toaster oven. Therefore, while Pyrex can generally be safely used in the oven, caution must be exercised to prevent any potential damage.

Can Pyrex withstand 500 degrees?

Pyrex glass products have been designed to withstand temperatures of up to 500 degrees Fahrenheit (260 degrees Celsius). However, it is recommended to use them at temperatures up to 425 degrees Fahrenheit (218 degrees Celsius) as a safety precaution. While there have been rare cases of successfully baking a pizza on Pyrex glass at 600 degrees Fahrenheit (315 degrees Celsius), it is advisable to avoid such extreme conditions to ensure the longevity and integrity of the glass.

Can you put cold Pyrex in the oven?

Yes, it is safe to put cold Pyrex in the oven. However, it is important to follow Pyrex’s recommendations by preheating the oven before placing the glass dish inside. This helps prevent exposing the Pyrex to sudden temperature changes. Additionally, allowing the Pyrex to come to room temperature before placing it in the oven helps to prevent any potential damage to the glass.
