Can a Glass Coffee Pot Explode?

It’s a very valid question and something that can cause unnecessary worry among coffee makers who use glass coffee pots at home or in the office. In most cases, it’s OK to be using a glass coffee pot, but there are some important safety instructions to be aware of, to prevent any accidents or unfortunate incidents.

What Are the Risks of Using A Glass Coffee Pot?

The main risks associated with a glass coffee pot are that of shattering or rupture due to sudden temperature changes or incorrect use. When a glass coffee pot is repeatedly heated and cooled, for example by being washed regularly in very hot or cold water, the glass can become weakened and, in some cases, shatter or explode due to the pressure build-up from the heated coffee, water, or both.

Mitigating Risk

Here are some tips to help ensure that your glass coffee pot remains in one piece:

  • Avoid Sudden Temperature Changes: When going from cold to hot (or vice versa), always introduce the temperature changes gradually. Heat up your coffee pot slowly, and make sure it’s at a warm temperature before pouring in your hot coffee. The same goes for washing your coffee pot – make sure it’s cool before you start to clean it.
  • Stick to The Right Type of Glass: Various types of glass are used for making glass coffee pots, so make sure you invest in one made from high-quality, borosilicate glass. This type of glass is particularly resistant to thermal shock and breakage.
  • Avoid Overfilling and Overheating: Don’t overfill your glass coffee pot with coffee. As mentioned, pressure build-up could cause the glass to shatter or explode. Similarly, avoid leaving your coffee boiling for too long, as this can also cause the glass to overheat and sound an alarm. Keep an eye on your glass coffee pot and remove it from the heat source before it gets too hot.


Overall, glass coffee pots can be used safely, as long as they are used correctly and with care. Be sure to read the instructions carefully before using it, and follow the safety tips provided above. With the right precautions, you should be able to enjoy coffee from your glass coffee pot for many years to come.
