Hi, Swim just finished his second extraction and this one gave him better results than the last try. (Green dmt 
) Swim has a couple of questions about the next steps. Ok, this time around he did a STB extract and put the siphoned layer of heptane in the freezer for approx. 16 hours. The result was a blurry yellowish colored solvent with small cottony clouds floating around that eventually settled on the bottom. Next, he proceeded to empty the solvent through a coffee filter into another smaller container. Kept the solvent and let the filter dry out. Results: [img:98aa0d3db8]http://img20.imageshack.us/img20/2513/yellowfilterlk3.th.jpg[/img:98aa0d3db8] My first question is what should he use to scrape this off the filter without dragging pieces of the filter along with the extracted material? Secondly, should swim seriously consider a recrystallization? If so, would heptane work instead of naphtha? Lastly, can anyone direct swim to a [u:98aa0d3db8]beginner's[/u:98aa0d3db8] guide to recrystallization? Thanks for your time
