However, putting hot Pyrex directly into the refrigerator can lead to a thermal shock, which may cause the glass to break.
To avoid this, it is recommended to let hot Pyrex cool down to room temperature before placing it in the refrigerator. This will allow for a gradual temperature change and minimize the risk of breakage. Additionally, it is advisable to place a hot Pyrex dish on a cooling rack or a heat-resistant trivet to further promote even cooling.
Another factor to consider is the impact on other items in the refrigerator. Placing a hot Pyrex dish in the refrigerator can cause the surrounding air temperature to increase, which can potentially spoil other perishable items. To prevent this, it is best to allow hot Pyrex to cool down before refrigeration.
Is it safe to put hot Pyrex in the refrigerator?
Many people wonder whether it is safe to put hot Pyrex in the refrigerator. Pyrex is a type of glass cookware that is known for its thermal stability and durability. While Pyrex is designed to withstand high temperatures, it is not recommended to put hot Pyrex directly into the refrigerator.
Why you should avoid putting hot Pyrex in the refrigerator
Putting hot Pyrex in the refrigerator can potentially cause the glass to shatter. This is because the sudden change in temperature can create thermal shock, which occurs when the glass expands or contracts at a rapid rate. This thermal shock can lead to fractures or breakage of the glass.
Additionally, placing hot Pyrex in the refrigerator can also affect other items in your fridge. The heat from the Pyrex can raise the temperature inside the refrigerator, causing other foods to spoil more quickly. It can also strain the refrigerator’s cooling system, leading to increased energy consumption.
What to do instead
If you need to cool your Pyrex dish quickly, it is recommended to let it cool to room temperature first. You can place the hot Pyrex on a cooling rack or trivet to speed up the cooling process. Once it has reached room temperature, you can then transfer it to the refrigerator for storage.
Alternatively, you can transfer the hot food into a shallow container that is made specifically for fridge-to-oven use. These types of containers are designed to withstand rapid temperature changes and can safely go from hot to cold without any issues.
It’s important to prioritize safety and take precautions when handling hot Pyrex. By following these guidelines, you can ensure the longevity of your Pyrex cookware and keep your refrigerator running efficiently.

Temperature Differences
Understanding temperature differences is crucial for proper usage of Pyrex in the refrigerator. Pyrex is made from a type of glass called borosilicate glass, which is known for its ability to withstand high temperatures. However, there are limits to the temperature changes it can handle.
Thermal Shock
When a hot Pyrex dish is placed in the refrigerator, it experiences a sudden change in temperature. This rapid shift in temperature can lead to thermal shock, which is the cracking or breaking of the glass due to stress. While Pyrex is designed to withstand thermal shock better than regular glass, extreme temperature differences should still be avoided to prevent damage.
Safe Temperature Range
The safe temperature range for Pyrex glass is from -40°F to 932°F (-40°C to 500°C). It is important to note that the glass itself can withstand these temperatures, but sudden changes within this range can still cause thermal shock. To keep Pyrex safe, it is best to avoid extreme temperature fluctuations, such as transferring a hot dish from the oven directly to the refrigerator.
If you want to refrigerate a hot Pyrex dish, it is recommended to let it cool down to room temperature first. You can do this by placing the dish on a heat-resistant surface, like a trivet or cutting board, for some time. Once the dish has cooled to a safe temperature, it can be safely placed in the refrigerator.
It is also worth noting that Pyrex lids may have temperature restrictions different from the glass. Always check the manufacturer’s instructions for specific guidelines on using Pyrex lids and refrigeration.
By being mindful of temperature differences and following proper practices, you can safely use Pyrex in the refrigerator without risking damage to the glass.
Thermal Shock
One of the risks associated with putting hot Pyrex in the refrigerator is thermal shock. Thermal shock occurs when there is a rapid change in temperature, causing a material to crack or shatter. Pyrex glass is designed to be resistant to thermal shock, but it is not invulnerable.
When you place hot Pyrex in the refrigerator, the sudden change in temperature can cause the glass to contract rapidly. This contraction can create stress within the glass, which may lead to cracks or breakage. The risk of thermal shock is higher if the temperature difference between the hot Pyrex and the refrigerator is significant.
To prevent thermal shock, it is best to allow hot Pyrex to cool down to room temperature before placing it in the refrigerator. This allows the glass to gradually adjust to the change in temperature, reducing the risk of cracking or breaking. Additionally, you can also place a hot Pyrex dish on a cooling rack or a dish towel to further help dissipate the heat.
If you need to cool down hot Pyrex quickly, it is recommended to place it in a lukewarm water bath or on a heat-resistant surface, such as a trivet or silicone pad, before transferring it to the refrigerator. This gradual cooling process helps to minimize the risk of thermal shock.
In summary, thermal shock is a potential concern when putting hot Pyrex in the refrigerator. To avoid the risk of cracking or breaking, it is best to cool down hot Pyrex to room temperature before refrigerating it or use gradual cooling methods like lukewarm water or heat-resistant surfaces.
