Pyrex is a popular brand for kitchenware, known for its durable glass containers. But if you're wondering, are Pyrex containers microwave safe? The short answer is yes, but there are some important things you should know before using them in the microwave.
What is Pyrex Made Of?
Pyrex containers are made from borosilicate glass or tempered glass. Borosilicate glass is known for its ability to withstand thermal shock, meaning it can handle rapid temperature changes without breaking. Tempered glass, on the other hand, is strengthened through a process of extreme heating and cooling, making it durable and less likely to shatter.
Can You Microwave Pyrex?
Yes, you can microwave Pyrex containers, but with caution. Pyrex glass is designed to be heat-resistant, so it's generally safe for use in the microwave. However, there are some important guidelines to follow to ensure safety and prevent damage:
- Check the Label: Make sure your Pyrex container is labeled as microwave-safe. Most Pyrex glassware is safe for the microwave, but some older or decorative pieces may not be.
- Avoid Thermal Shock: Even though Pyrex is designed to handle heat, sudden temperature changes can cause it to crack or shatter. Avoid putting a cold Pyrex container directly into a hot microwave. Similarly, don’t place a hot Pyrex dish on a cold surface. Let it cool down gradually or warm up slowly.
- No Direct Heat Sources: Pyrex is not safe on stovetops or under a broiler. Direct heat sources can cause the glass to break, even in the microwave. Always ensure the heating is even and controlled.
- Use Microwave-safe Lids: If your Pyrex container comes with a lid, make sure it's also microwave-safe. Plastic lids can warp or melt if they’re not designed for microwave use.
- Avoid Overheating: While Pyrex can handle high temperatures, it’s still glass and can be damaged by overheating. Use medium heat settings and avoid microwaving for too long.
Tips for Safely Using Pyrex in the Microwave
- Gradual Temperature Change: Always allow your Pyrex to adjust to room temperature before microwaving.
- Use Low to Medium Heat: Start with lower power settings to prevent overheating and stress on the glass.
- Avoid Direct Contact with Microwave Walls: Place the Pyrex container on a microwave-safe plate or dish to avoid direct contact with the hot microwave walls.
- Do Not Overfill: Leave space in the container to allow food to heat evenly and prevent spills.

FAQs
1. What Happens if Pyrex Breaks in the Microwave?
If Pyrex does break in the microwave, it will likely shatter into large, dangerous pieces. Always handle broken glass with care, wearing gloves and using tools to avoid injury.
2. Can You Microwave Pyrex Straight from the Fridge?
It’s not recommended to microwave Pyrex straight from the fridge. The sudden temperature change can cause the glass to break. Let the container come to room temperature first or warm it up gradually in the microwave at a lower power setting.
3. Can Pyrex Go From Freezer to Microwave?
No, Pyrex should not go directly from the freezer to the microwave. This sudden temperature change is too extreme and increases the risk of the glass shattering. Thaw the container first before microwaving.
4. Is it Safe to Microwave Food in Pyrex With a Metal Rim?
No, it is not safe to microwave any container with metal, including Pyrex with metal rims. The metal can spark and cause a fire or damage the microwave.
