boiling them works, however there's always the danger of dropping it in cold water and cracking (I think this can happen?) or having it slip out of whatever you're holding it with on a hard surface. I read once somewhere, probably here someone boiled water and put one of those steam top things on the pot and put the stem where the steam comes out and let it rip, causing the steam to go into the dry piece and loosen up all that resin
also boiling stinks
