Yea, again I have boiled it in the past and nothing happened, and later I was told of the risk so I just don't, because it does make sense if there is an expanding pocket if air it could happen. But chances are it would just crack and not explode if boiled. So I just been rinsing them with hot running water from the sink and I haven't seen a difference, but then again I bought mine from home Depot so it has probably been in a hot Warehouse and dry for a long time, if one is collecting from outside there is probably a higher risk.
