Are Glass Coffee Mugs Microwave Safe?
Glass coffee mugs are very popular and most households have some. For those who like to heat their coffee, the question arises- are glass coffee mugs microwave safe?
The Properties of Glass
Glass is an incredibly versatile material and is used for many purposes. It is known for its heat resistant and non-porous qualities, however before you place your glass coffee mug inside the microwave remember it can be affected by certain types of glass.
Types of Glass
Tempered (safety) glass is a popular choice for tableware items because it can withstand to high temperatures. Therefore, when it is exposed to heat there are no risks of it breaking and it is considered to be safe to use in the microwave.
On the other hand, untreated (normal) glass is much more fragile and tends to break under heat. This type of glass is not safe to use in the microwave. To be sure, check the tags of the glass coffee mug because they may include a warning that it is not microwave safe.
Tips to Prevent Accidents
Even when using tempered glass, there are still some steps you can take if you want to use your glass coffee mug in the microwave.
- Never heat your coffee mug for longer than a few minutes
- Always keep the mug away from the walls of the microwave
- Make sure to add enough liquid (in this case, water) to the mug
- Test the temperature of the mug before drinking your coffee
Conclusion
In conclusion, glass coffee mugs are generally safe to use in the microwave, as long as they are made of tempered glass. If you are unsure, you should check the tags of the mug and take some preventative steps to avoid any accidents.
