Using an espresso maker like this,  Fill the bottom compartment with acetone and add citric acid. Place the funnel into the bottom cup and fill it with root bark ground as fine as possible. Screw on the top and place it on an electric heater. (note that acetone is flammable so conduct this under a fume hood or outside.)

Then make a FASA solution and get it as cold as possible. Once the hot acetone passes threw the bark it will return to its liquid state. Add this immediately to the cold acetone and let DMT Fumarate precipitate out. I haven't conducted this experiment yet and would like to get input on its efficiency and if there are any hazards I cant foresee.
