Yeah I'm sure it's a rare occurrence, but it just turned me off from using Moka pots in favor of a Turkish coffee cezve or French press, neither of which can explode.

I've cracked a couple of french presses, though. Thin glass + cold + hot and back makes it brittle.

The solution was to not use metal spoons for stirring -- wooden or plastic chop sticks work pretty well -- but it's frustrating. By comparison the drip coffee machine or the moke pot haven't ever had a failure.

I'm sure it's a crime in some countries, but I use a single wooden chopstick for stirring. It's the right size + doesn't damage the glass.

Wooden chopsticks are fantastic for stirring! I have a double-walled stainless steel French Press and still use a chopstick for stirring.
