I've never broken any of my pieces so i guess I'm lucky. two of my friends and I boiled our pieces once though and like we got stoned so we forgot to check the water. Most of it evaporated and made one of my friends pipes break in half. Mine has a small crack in it now, but it's barely noticable and doesn't affect it.

Oh, I had a shurlock one time and i gave it to one of my friends. Her mom ended up breaking it a few months later. That kind of pissed me off because that was a really cool piece. Hated to see it go.
