When it comes to storing food in the freezer, safety is a top priority. With the risk of contamination and spoilage, it’s essential to use containers that are designed for freezer use. Pyrex bowls are a popular choice for many home cooks, but are they truly freezer safe? In this article, we’ll delve into the world of Pyrex bowls and explore whether they’re suitable for freezer storage.
What are Pyrex Bowls?
Pyrex is a brand of heat-resistant glassware that’s been a staple in many kitchens for decades. The company was founded in 1908 and has since become synonymous with high-quality glassware. Pyrex bowls are made from a type of glass called borosilicate, which is known for its thermal shock resistance and durability.
Are Pyrex Bowls Freezer Safe?
The short answer is: it depends. Pyrex bowls are not inherently freezer safe, but some models are designed with freezer-safe materials. The company’s official stance is that their bowls are not recommended for freezer use, but some users have reported success in storing food in them without issue.
What Makes a Container Freezer Safe?
For a container to be considered freezer safe, it must be made from a material that can withstand extreme temperatures and humidity. Freezer-safe containers are typically made from plastics, metals, or glass that are specifically designed to resist cracking, shattering, or warping when exposed to cold temperatures.
Materials Used in Pyrex Bowls
Pyrex bowls are made from a type of glass called borosilicate, which is a combination of boron and silicon dioxide. This material is known for its thermal shock resistance, meaning it can withstand sudden changes in temperature without breaking. However, it’s not necessarily designed for freezer use.
What Happens When You Put Pyrex Bowls in the Freezer?
When you put Pyrex bowls in the freezer, there are a few potential risks to consider:
- Thermal Shock: The sudden change in temperature can cause the glass to expand and contract, potentially leading to cracking or shattering.
- Humidity: Freezing temperatures can cause moisture to condense on the surface of the glass, which can lead to water spots or mineral deposits.
- Chemical Reactions: Some chemicals or substances can react with the glass or other materials in the bowl, potentially causing discoloration or damage.
Alternatives to Pyrex Bowls for Freezer Storage
While Pyrex bowls may not be the best choice for freezer storage, there are many other options available. Here are a few alternatives:
Freezer-Safe Glass Containers
Some glass containers are specifically designed for freezer use. Look for containers made from borosilicate glass or tempered glass, which are more resistant to thermal shock and can withstand freezer temperatures.
Examples of Freezer-Safe Glass Containers
| Brand | Model | Features |
|---|---|---|
| Pyrex | Freezer-Safe Glass Storage Containers | Tempered glass, airtight lids, dishwasher safe |
| Anchor Hocking | Fire-Keramic Glass Storage Containers | Borosilicate glass, airtight lids, microwave safe |
| OXO | Freezer-Safe Glass Storage Containers | Tempered glass, airtight lids, dishwasher safe |
Plastic Containers
Plastic containers are another popular option for freezer storage. Look for containers made from BPA-free, food-grade plastic that are specifically designed for freezer use.
Examples of Freezer-Safe Plastic Containers
| Brand | Model | Features |
|---|---|---|
| Ziploc | Freezer Bags | BPA-free, airtight seals, dishwasher safe |
| Rubbermaid | Freezer Storage Containers | BPA-free, airtight lids, dishwasher safe |
| Stasher | Reusable Silicone Freezer Bags | BPA-free, airtight seals, dishwasher safe |
Conclusion
While Pyrex bowls may not be the best choice for freezer storage, there are many other options available. By choosing the right container for your needs, you can ensure that your food stays fresh and safe to eat. Remember to always check the manufacturer’s instructions and guidelines for freezer storage, and to handle your containers with care to avoid damage or breakage.

FAQs
Q: Can I put Pyrex bowls in the freezer without damaging them?
A: It’s not recommended to put Pyrex bowls in the freezer without checking the manufacturer’s instructions first. While some users have reported success in storing food in Pyrex bowls without issue, there’s always a risk of damage or breakage.
Q: Are all glass containers suitable for freezer storage?
A: No, not all glass containers are suitable for freezer storage. Look for containers made from borosilicate glass or tempered glass, which are more resistant to thermal shock and can withstand freezer temperatures.
Q: Can I use plastic containers in the oven?
A: It depends on the type of plastic container you’re using. Some plastic containers are designed for oven use, while others are not. Always check the manufacturer’s instructions before using a plastic container in the oven.
Q: Are freezer-safe containers more expensive than regular containers?
A: Yes, freezer-safe containers are often more expensive than regular containers. However, they’re designed to withstand extreme temperatures and humidity, making them a worthwhile investment for long-term food storage.
Q: Can I use Pyrex bowls for both freezer and oven use?
A: No, it’s not recommended to use Pyrex bowls for both freezer and oven use. Pyrex bowls are designed for stovetop and microwave use, but not for freezer or oven use. Using them for both purposes can cause damage or breakage.
