Okay, so I did q21q21's tek with 50 g(test run) and crystals have precipitated nicely (: However, there's a bunch just floating a round and there's a bunch stuck to the sides and bottom of the glass container. How do I pour out the naptha (I plan on reusing) without take the crystals with it?

People say use a coffee filter but how does that work? The naptha goes through but how do I get the crystals off of the coffee filter? What technique do I do this with?

Thanks for the help guys!

Don't use coffee filters to catch floaters...they will just melt back into the solvent soaked fabric as the temperature rises and be lost.
If you get floaters, the best way it to either freeze longer or pour off very carefully and slowly. Use a baster if necessary or hold them back with some fine mesh.
Even if a couple escape you can reuse the solvent for the next pull and get them back.
