I hold it above and let it melt at first..second hit I just stick the flame right on the changa..I never noticed any DMT being destroyed etc..though I prefer orange oily limo pulled DMT, and apparently the oils protect the spice from burning..

I have NEVER had a problem with just feathering the bowl lightly with the flame. Just dont hold the flame there for an extended period.

I think people exagerate a bit about how you will burn DMT if any flame touches it..just like how there is this myth that you need a torch lighter to smoke salvia when in reality a match works just as well.
