So the title sais it all. Seeing I have 'lost' my vacuum set-up, but I still had some flowers to work with, I went ahead and did the extraction. Slowly double boiled it till no more bubbles appeared, wipping it from time to time, keeping it al on a very low temp. End result for now looks damned fine if i may say so myself, but when heated it still sparkles a bit. I am willing to try and desolve it into iso-propyl in order to winterize it. So the thing I wanted to ask: Will this work to remove plant waxes and fats? Will this help in removing the butane, I once saw someone doing this with alcohol and it seemed to do the trick. And I can get alcohol (94%), so would that maybe be a better option then the iso? Don't know if one might be more 'harmful'then the other? Am asking about ISO because last time I winterized with (grain)alcohol i had a really hard time getting the alcohol back out. Any tips and or suggestions are welcome.
