We use to use acetone but I will be using Isopropyl.
Soak the leaf n trim in glass jars (make sure the leaf matter is covered with Isopropyl) with the lid on for at least a week...the longer the better. Probably no need to go any longer than 2 weeks.
After its been soaking long enough , strain out all the leaf matter....I use a wire sift to get the majority of the big stuff out, then I use a coffee filter to get the rest of the floateis out.
Get a electric frying pan, put about 20mm to 30mm of water in the frying pan, put something in the frying pan for a pot to sit on....I use wooden spoons so only the water is transferring heart. Put the liquid into a large pot and then put that pot onto the wooden spoons in the frying pan.
Heat the frying pan until the water is nearly boiling (don't let it boil) , make sure the water in the frying pan doesn't dry out. Keep heating until the solvent evaporates , there will only be a think oil left once the solvent has evaporated (should be as thick as room temp honey).
Obviously make sure this is done in a well ventilated area. The heating process will take hours...it will depend on how much your making as to how many hours.
There ya go @peachfuzz
Oh I almost forgot....we use wet leaf matter. I have read that some other methods online use dry material.
Also I should mention that from memory...you need to put the spoons in and then the pot onto the spoons, before putting the water in....other wise the spoons will float and make it difficult to get the pot on them evenly.
