As a borosilicate jar supplier, I often get asked if borosilicate jars can be used in the microwave. It's a valid question, especially considering the convenience of microwaving food and drinks. In this blog post, I'll dive into the science behind borosilicate glass and its compatibility with microwaves, and share some tips on using borosilicate jars safely in the microwave.
What is Borosilicate Glass?
First things first, let's talk about what borosilicate glass is. Borosilicate glass is a type of glass that contains boron trioxide, which gives it some unique properties. Compared to regular soda-lime glass, borosilicate glass has a lower coefficient of thermal expansion. This means it can withstand rapid temperature changes without cracking or shattering. That's why you often see borosilicate glass used in laboratory equipment, cookware, and even some high-end drinking glasses.
Can Borosilicate Jars Go in the Microwave?
The short answer is yes, most borosilicate jars can be used in the microwave. Thanks to their low thermal expansion rate, borosilicate jars can handle the heat generated by microwaves without breaking. However, there are a few things you need to keep in mind to ensure safe use.
Check for Any Metal Parts
Some borosilicate jars may have metal lids, handles, or decorations. Metal and microwaves don't mix well. When metal is exposed to microwaves, it can cause arcing, which is basically sparks flying inside the microwave. This can damage your microwave and even start a fire. So, before you put your borosilicate jar in the microwave, make sure to remove any metal parts.
Look for Microwave-Safe Labels
Many borosilicate jars come with a label indicating that they are microwave-safe. This is a good sign that the jar has been tested and is suitable for use in the microwave. If your jar doesn't have a label, you can still use it, but it's a good idea to test it first.
Do a Quick Test
If you're unsure whether your borosilicate jar is microwave-safe, you can do a simple test. Fill the jar with a cup of water and place it in the microwave next to an empty glass container of the same size. Heat the water on high for one minute. If the water gets hot and the jar remains cool to the touch, it's likely safe to use in the microwave. If the jar gets hot or shows any signs of damage, don't use it in the microwave.
Benefits of Using Borosilicate Jars in the Microwave
Now that we've established that borosilicate jars can be used in the microwave, let's talk about the benefits.
Durability
As I mentioned earlier, borosilicate glass is more durable than regular glass. It can withstand repeated heating and cooling cycles without cracking or breaking. This means you can use your borosilicate jars in the microwave over and over again without having to worry about them breaking.
Safety
Borosilicate glass is non-toxic and doesn't release any harmful chemicals when heated. This makes it a safe choice for storing and heating food and drinks in the microwave.
Versatility
Borosilicate jars come in a variety of shapes and sizes, making them suitable for a wide range of uses. You can use them to store leftovers, heat up soups and stews, or even make individual desserts in the microwave. For example, our Round High Borosilicate Storage Jar is perfect for storing dry goods or heating up small portions of food. The Hexagonal High Borosilicate Sealed Tank is great for storing liquids and can also be used in the microwave. And if you're looking for a smaller option, our 500ml Borosilicate Sealed Jar is ideal for single servings.
Tips for Using Borosilicate Jars in the Microwave
To get the most out of your borosilicate jars in the microwave, here are some tips to keep in mind.
Don't Overheat
Even though borosilicate glass is heat-resistant, it's still important not to overheat it. Overheating can cause the glass to expand too quickly and crack. To avoid this, heat your food in short intervals and stir it in between to ensure even heating.
Use a Microwave-Safe Lid
If you're using a lid on your borosilicate jar in the microwave, make sure it's microwave-safe. Some lids may melt or release harmful chemicals when heated in the microwave. You can use a microwave-safe plastic wrap or a silicone lid instead.
Let the Jar Cool Down
After you've finished using your borosilicate jar in the microwave, let it cool down before handling it. The glass may be hot, and touching it with bare hands can cause burns.
Conclusion
In conclusion, borosilicate jars are a great option for use in the microwave. They are durable, safe, and versatile. Just make sure to check for any metal parts, look for microwave-safe labels, and follow the tips I've shared to ensure safe use.
