We are well aware of the fact that not all containers or dishes are microwave safe, especially foil-coated (aluminum foil) or styrofoam! The next on the list can be cold glass if it’s microwaved! WHY? Well due to the sudden change in temperature! A cold glass has contracted particles that suddenly loosen up when introduced to heat! This is the same reaction when you pour hot coffee into an ice-cold mug! The mug cracks right? The same happens to the cold glass in a microwave!

Hence to avoid breaking your glass mug or container, it’s better to leave it at room temperature so that it can get its normal temperature back! Once the glass regains its normal temperature, you are free to microwave it as it won’t cause a hazard!

Types Of Glass And Their Reaction To Excessive Heat!

GLASS IN MICROWAVE

Glassware is deemed safe for microwaving, but how much heat can your glassware handle depends on the kind of glassware you are using! If your glass is thin or delicate, then obviously it can’t handle much heat and will shatter or crack after three minutes of use! Glasses that are curved in shape and are made of crystals are likely to explode as they can’t handle uneven temperatures to a large extent!

Ordinary glassware can, at best, handle your microwave for 3 minutes! Any further increase in time can make them shatter or explode! 

Conclusion

Glass containers or mugs are microwave safe as long as they do not contain any metal gilding or patterns etched on them! You can microwave your glass to check if it’s microwave-safe or not by following a five-step process! The cold glass should not be directly put in the microwave as it might shatter or even explode! Hence, it’s better that you are aware of what to and what not to do while using a microwave!
