Tips for Using Glassware in the Microwave
It’s important to follow some safety tips when using glassware in the microwave to avoid damaging your microwave or hurting yourself. Here are some things to keep in mind:
- Check for a “microwave-safe” label. As mentioned above, only microwave-safe glassware should be used in the microwave. Check the bottom of your mug to make sure there is a symbol clearly showing it is microwave-safe.
- Choose a mug with a thicker base. Thicker mugs are more likely to withstand the heat and pressure of the microwave. Avoid mugs with thin areas or a narrow base.
- Make sure the mug is clean. Bleach or other toxic chemical residue can leach into food when cooked or heated in the microwave. Make sure you clean your mug (with soap, not abrasives) before putting it in the microwave.
- Start with shorter cooking times. It may be tempting to jump right in and heat your cup of coffee for a few minutes, but it’s wise to start with a shorter cooking time of 15-20 seconds and then check the temperature of your drink before continuing.
- No metal parts. Metal parts, such as handles, should never be put in a microwave. Also, make sure your mug doesn’t have any metal decorations or trim.
- Avoid extreme temperature changes. Rapid extreme temperature changes can cause glass to break or shatter, so it’s best to avoid pouring hot coffee into an ice-cold mug and vice versa.
By following the above tips, you should be able to safely put a glass coffee mug in the microwave. Just remember to exercise caution and check for the “microwave-safe” label before using it.
