Can You Put a Cold Pyrex Dish in the Oven? A Guide to Proper Usage and Safety
Can You Put a Cold Pyrex Dish in the Oven?
Yes, you can put a cold Pyrex dish in the oven, but it is recommended to let it come to room temperature for about 1 hour before heating to reduce the risk of the glass shattering due to the extreme change in temperature.
Key Points:
- Pyrex dishes can be placed in the oven even if they are cold.
- It is advisable to let the Pyrex dish come to room temperature for approximately 1 hour before heating it in the oven.
- This precautionary step helps minimize the risk of the glass shattering.
- The shattering is caused by the sudden change in temperature.
- Allowing the dish to come to room temperature gradually helps mitigate this risk.
- Taking this precaution ensures the safe use of Pyrex dishes in the oven.
Did You Know?
1. Pyrex dishes were originally developed in 1915 by a scientist named Jesse Littleton, who was trying to find a material that could withstand extreme temperature changes without shattering. The iconic glass used in Pyrex dishes became famous for its thermal shock resistance properties.
2. While most Pyrex dishes are oven-safe, not all are suitable for direct heat. Pyrex bakeware made before 1998 is not recommended for stovetop use, as it may be more prone to thermal stress and potential breakage.
3. The term “Pyrex” actually comes from the Greek word “pyro,” meaning fire, and the English word “rex,” meaning king. So, Pyrex essentially translates to “king of fire,” emphasizing its heat resistance quality.
4. Pyrex glass is still manufactured using a unique formula that involves adding boron, making it more durable and less susceptible to thermal expansion than regular glass.
5. In 2018, a team of researchers at the Corning Museum of Glass discovered that Pyrex dishes from the 1970s and earlier contained a small percentage of toxic lead oxide in their composition. This led to a temporary halt in production and reevaluation of the manufacturing process to ensure the safety of future Pyrex products.
Can Pyrex Dishes Go From Fridge To Oven?
Pyrex dishes have long been a staple in many kitchens due to their versatility and durability. One common question that often arises is whether it is safe to put a cold Pyrex dish directly from the fridge into the oven.
The answer is yes, Pyrex dishes can go directly from the fridge to the oven. However, it is important to note that there is a higher risk of the glass shattering due to the extreme change in temperature. To minimize this risk, it is recommended to allow Pyrex to come to room temperature for about 1 hour before putting it in the oven.
The Importance Of Allowing Pyrex To Come To Room Temperature Before Heating.
Pyrex is made from a patented form of toughened glass that can withstand extreme temperatures. However, it is not completely resistant to thermal shock. Most modern-day Pyrex dishes are made from soda-lime glass, which is not as resistant to extreme temperature changes and can shatter if exposed to them.
On the other hand, the original form of Pyrex, made from borosilicate glass, can withstand temperature changes and can be taken directly from the fridge to the oven without breaking. If you are unsure about the type of Pyrex dish you own, it is recommended to bring it to room temperature before heating to avoid any potential hazards.

Pyrex Dishes And Their Resistance To Extreme Temperatures.
Pyrex dishes come in a range of sizes and are versatile enough to be used in both the oven and freezer. Since 1915, they have been designed to withstand high temperatures and have become a favorite among cooks and bakers.
However, it’s important to keep in mind that Pyrex dishes are not resistant to thermal shock. Extreme changes in temperature can cause the glass to shatter. Therefore, do not place hot Pyrex dishes on wet or cool surfaces and avoid adding liquid to hot glassware. These precautions will help prevent any accidents and ensure the longevity of your Pyrex dishes.
Guidelines For Using Pyrex Dishes In The Oven And Freezer.
When using Pyrex dishes in the oven, it is important to follow some guidelines. To minimize the risk of shattering, it is recommended to let prepped dishes rest on the counter for 15 to 30 minutes before placing them in the oven. This allows the Pyrex dish to gradually adjust to room temperature.
Pyrex dishes are oven-safe and can withstand temperatures up to 425ºF. However, they should not be used in the broiler. It is crucial to check for any chips or cracks in vintage Pyrex dishes before use. Using them in this condition can result in complete cracking or the release of glass chips.
Freezing Pyrex dishes is generally not recommended due to their low resistance to thermal shock. However, pre-1998 borosilicate glass dishes are an exception. These dishes can safely go from the freezer directly to the oven without any issues.
Safety Precautions For Handling And Heating Pyrex Dishes.
To ensure the safe handling and heating of Pyrex dishes, it is crucial to follow a few safety precautions. Hot Pyrex dishes should not be placed in cold water, as this sudden change in temperature can cause them to crack. Additionally, hot pans should be placed on a hot pad or trivet to protect the pan and countertop.
When defrosting frozen food in Pyrex dishes, it is recommended to do so by leaving the dish at room temperature. Similarly, hot food should be allowed to cool to room temperature before being refrigerated. These steps will help to prevent any potential accidents and ensure the longevity of your Pyrex dishes.
Pyrex dishes can safely go from the fridge to the oven, but it is important to note that there is a higher risk of the glass shattering due to the extreme change in temperature. Following the guidelines of allowing Pyrex to come to room temperature before heating, using Pyrex dishes within their recommended temperature limits, and practicing safety precautions will ensure the proper usage and safety of Pyrex dishes in the kitchen.
Frequently Asked Questions
Can I put Pyrex from fridge to oven?
Yes, you can transfer Pyrex from the fridge to the oven, but it is advisable to exercise caution. Although it is unlikely to cause any damage, it is best to avoid sudden temperature changes. To ensure its durability, it is recommended to let the dish rest at room temperature for a short period before placing it in the oven to prevent any potential issues.
Can Pyrex dishes go from cold to hot?
When utilizing Pyrex or any type of glass bakeware, it is essential to steer clear of quick and drastic temperature transitions. It is not recommended to place very cold Pyrex dishes in a hot oven or do the reverse, as sudden changes in temperature can potentially lead to breakage or shattering. It is therefore crucial to handle Pyrex dishes with caution and avoid subjecting them to extreme temperature variations.
Can I put a cold glass baking dish in the oven?
Yes, you can put a cold glass baking dish in the oven without any issues. In fact, it is a common practice in some recipes to use a cold glass dish to prevent the dish from cracking or forming bubbles. Just make sure to follow the recipe instructions and avoid sudden temperature changes, such as placing a cold dish in a preheated oven, to ensure the dish’s safety.
Can I put cold Pyrex in the microwave?
Yes, it is safe to put cold Pyrex in the microwave. Pyrex glass containers are designed to withstand the temperature changes from the fridge to the microwave. You can even transfer them directly from the freezer to the microwave if needed. However, it is recommended to let the Pyrex container sit out for about an hour before microwaving to prevent it from taking longer to reheat.
