It should be capable of quickly heating up, and once it has reached the desired temperature, could be used to stir a cold cup of coffee or tea to bring it back to the freshly made hot temperature? :wink:

It may seem like a good idea at the time but.. never stir your cold coffee with a soldering iron.
