thank you for your answer. i read the methods you suggested. they are extremly similar to the tech i found on erowid. But because the erowid tutorial has a lot of graphics, i'd preffer sticking with that one. It will be easier for my first extraction. Because i haven't read much about defatting on other extracthing teks, i believe it's really not that necesarely, so i guess i will just skip it. Now - i have another question. How important is the solvent type i use? I can't find VM&P Naphta here, which seems to be pretty popular in the extraction techs. Instead, i can found a lot of fast evaporating solvents. Can i use any of them? It says on most of the boxes that it can be used for disolving fat, and to dillute varnish and paint. Should i pick one of those, instead of the famous VM&P Naphta?
