Can You Microwave Glass?

Most glass products are safe for microwaving.

However, some others are not. So, it’s essential to determine if your glass products are suitable for reheat.

You can try checking its bottom or sides for a microwavable sign. 

If it is not possible, the best thing is to test it by filling it with water at high heat for about 60 seconds.

If you use a heat-resistant glass container, the water will be hot while the container stays cool. 

Conversely, if your product becomes hot while the water stays cold, your product is not suitable for microwaving.

It is essential to double-check the product’s material when purchasing a container, especially if you intend to use it for microwaving.

How to Find the Safe Label?

Flip your container over to see if it is labeled safe. If your product is compatible, you will usually find the microwaveable title on the bottom of it.

If your product comes with the “microwave-safe” title, don’t hesitate to use it.

Yet, some products don’t go through the FDA approval process to be labeled. 

So, if your container does not have clear indicators, you need to do a quick test, as we mentioned above.

Avoid using products with metal rims as the metal may react with electromagnetic waves.
