Changa was going to be the next step if the cerdict was this pipe may not work.  i've read about it briefly before, but the link posted was a lot more descriptive and helpful.  Something I didn't have time to type up, it may be dmt oxide.   It's kept frozen right now in brown balls which melt to oil almost immediately ar room temp, but I've also read that may just be left over tree fats/impurities and not necessarily oxide.   Would you have to recrystalize before the changa process or would SWIM just go about the steps as normal?
