After struggling along with major emulsions when attempting to extract dmt from mhrb, SWIB came
across an erowid posting (and learned a new word - "amphoteric") that indicated that most of the tars and other useless substances are soluble at a very low pH, but fall out of solution at a slightly higher pH. Experimentation showed this to happen around pH 5. It leaves a gray/brown precipitate thay may be easily gravity filtered out. The question, of course, is at this pH, is there a tendency for the DMT to come out of solution, too?
SWIB assumes that as long as the solution is at least mildly acidic, the DMT will stay in the aqeuous phase.
peace,
