Yes, glass is typically safe to use in a microwave because of its high tolerance to heat. However, you must confirm that the glass is labeled microwaveable.
Do you know using the wrong container can damage your microwave? I learned this the hard way after spending unbudgeted money to get a new one.
I won’t blame you if you think you can just pick any random container and put it inside your microwave to reheat your food. This was the same thought I had until I entered a smoke-filled kitchen because I had put a non-microwaveable container inside my microwave.
Since you are reading this article, it means you are more cautious than I was, and I will let you learn from my bad experience.

Why Does Glass Break in a Microwave?
When glass is not microwaving safe, you will see tiny air bubbles as it expands since the increased heat causes the glass substance to stretch unevenly. When these bubbles keep becoming hotter, the glass will eventually break.
Also, when placed in the microwave, a glass with a safety label may shatter if it has minute chips or cracks. Your glassware may break as a result of uneven heating.
Before placing the glassware in the microwave, inspect it. Glass with silver or gold rims should not be microwaved because the metal may react with electromagnetic radiation.
How long is it safe to microwave glass?
You may use glassware in the microwave after making sure it is safe to use there. According to conventional guidance, glassware shouldn’t be microwaved for more than three minutes. It would help if you didn’t leave it there for an extended period.
Glass jars, cups, and jugs are examples of microwave-friendly objects yet may come with different instructions. If so, you should look at their labels to determine how long you may microwave them. Simple.
Steps in checking if your glass is microwave safe
- Step 1: Check the Plate
the first and best way to know if the glass is microwave safe is to check the glass. You will usually find this under the glass. You might have it in words such as “Microwave Safe” or “Not for Use in Microwaves.” You can find a symbol if you can’t find any lettering on the glass dish’s bottom.
So check for a symbol. It will look like a crude drawing of a microwave with some wavy lines within or above it. Those wavy lines, man. Another alternative sign is the shape of a plate or bowl with wavy lines above it or a sequence of wavy lines without a microwave or dish image. What features does all of this share? You’re safe if you look for those.

- Step 2: Microwave the glass containing water
Let’s do a quick scientific experiment to see if your glass can withstand being heated in the microwave. There is no need for a Bunsen burner or safety glasses; it will just take a moment.
First, put water in the glass container you are confident is microwave safe and place this in the microwave.
- Step 3: Heat up for a minute.
After placing the glass in the microwave, turn the heat up and leave for a minute. Open the door after that, and feel each of the canisters thoroughly. The glass can be used in your microwave if the water inside the microwave-safe cup is hot and the glass under examination is cold or slightly warm to the touch. On the other hand, if the glassware you are testing feels hot to the touch, then I’m sorry, your glass is not microwaved safely.
Additional tips
Now that you know exactly what to look for in a glass to determine whether or not it is microwave safe, here are some other tips.
- Avoid Sudden Changes in Temperature: Always prevent rapid temperature changes while using glass, particularly Pyrex. Don’t put hot glassware immediately on a wet or cool surface, on a cold metal surface or sink, or with a damp towel if the glassware is hot. The glassware should always be allowed to cool on a cooling rack, a potholder, or a dry towel. Before cleaning, cooling, or freezing the container, allow it to cool.
- Avoid Direct Heat: Never use Pyrex or glasses in a toaster oven, on a cooktop, over a flame, or in a broiler or grill.
- Add water, then heat: This protects against hot liquid spills that might break the glass.
- Always protect yourself using a potholder/glove: Always hold hot containers with a potholder or several layers of dry fabric in your hand for your safety.
FAQ
Can you microwave baby bottles made from glass?
Some glass infant bottles could be microwaveable. However, heating baby milk in the microwave is still a bad idea. These heaters don’t always heat things evenly. Before putting anything in your microwave, be sure it has been thoroughly checked.
When feeding a newborn, it’s crucial to take no chances. You may purchase specialized bottle warmers to heat the milk for your baby. This way, you can be sure it will be heated uniformly. Or, to put it another way, the milk can be warm in some spots and hot in others.
Can plastic be microwaved?
Plastic should never be microwaved. This is due to two factors. To start, a lot of plastic items melt in extremely hot temperatures. This implies that it can get mushy if you opt to microwave a plastic bowl. Don’t commit that error.
The second concern is the abundance of potentially dangerous compounds in plastic. Therefore, even if you could microwave some plastic containers, doing so may harm your health. Due to this, it is usually advisable to choose goods that can be heated in the microwave rather than plastic.
