The Rise of Duralex Glassware
Duralex is a French brand that has stood the test of time since it was founded in 1945. Renowned for its innovative glass products, Duralex is known for producing tempered glass, which is especially durable and resistant to thermal shock. This means it can handle sudden temperature changes, making it a popular choice for both home cooks and professional chefs.
Besides durability, Duralex bowls offer a modern aesthetic that complements any kitchen decor, making them not just functional but also stylish. The question arises: can you microwave Duralex glass bowls without worrying about safety or damage?
Understanding Duralex Glass Properties
Before delving into whether you can microwave Duralex glass bowls, it’s important to understand the unique properties of Duralex glass.
1. Tempered Glass
Duralex glass is made from tempered glass, a type of glass that has been heat-treated to increase its durability. During the manufacturing process, the glass is heated to high temperatures and then cooled rapidly, which imparts strength and resistance against thermal shocks. This means that Duralex bowls are less likely to shatter or crack when exposed to temperature changes compared to regular glass.
2. Heat Resistance
Duralex bowls are designed to withstand high temperatures, making them suitable for a variety of cooking methods, including baking and roasting. Most Duralex glass bowls can typically handle temperatures ranging from about -4°F to 600°F. This heat resistance is one of the key reasons they are favored for microwave usage.
3. Non-porous Surface
Another significant feature of Duralex glass bowls is their non-porous surface. This means that they do not absorb liquids or odors, making them easy to clean and perfect for storing food. When microwaved, they will not leach chemicals or substances into your food, ensuring a safe cooking environment.
Can You Microwave Duralex Glass Bowls?
The short answer is: Yes, you can safely microwave Duralex glass bowls. Their design and construction make them an excellent choice for microwave cooking. However, there are some safety tips and best practices you should follow to ensure the longevity of your Duralex glass and the safety of your cooking.
Important Safety Tips for Microwaving Duralex Glass Bowls
While microwaving Duralex glass bowls is generally safe, keeping a few crucial safety tips in mind can enhance your experience and protect your kitchenware.
1. Check for Damage
Before microwaving your Duralex bowl, inspect it for cracks, chips, or scratches. Using damaged glassware can lead to further deterioration and even shattering when placed in a microwave. Always prioritize safety by discarding any damaged bowls.
2. Avoid Extreme Temperature Changes
Although Duralex bowls are resistant to thermal shock, it’s advisable to avoid placing a cold Duralex bowl directly into a hot microwave, or vice versa. Sudden exposure to extreme temperatures can sometimes lead to glass breakage. Instead, allow your Duralex bowl to come to room temperature before microwaving it.
3. Use Microwave-Safe Lids
If your Duralex bowl comes with a lid, ensure it is also microwave-safe. Avoid using lids that are not designed for microwave use, as they can warp or melt. If you’re using a lid, leave it slightly ajar to allow steam to escape, which prevents pressure build-up.
4. Avoid Extreme Heating
Microwaving food at high power for extended periods can lead to overheating. To maintain the integrity of your Duralex bowl, opt for shorter time intervals and lower power settings. Stir the food occasionally to ensure even heating.
5. Gradually Increase Temperature
To further prevent thermal shock, gradually increase the temperature rather than starting with high heat. This gives the Duralex glass time to adapt to changes in temperature.
