If you have the equipment its quite easy.1.Buchner Funnel- this is a flat bottomed funnel .This needs to be in an erlynmyer flask (sp).with a siphon port on the side.2.A water siphon valve is a neat little thing you attach to a water faucet to produce a vacuum.If you have a vacuum pump use it.After you have stripped to crude resin from the organic fiber its mixed with a small amount of activated charcoal and poured into the filter paper in the funnel.Turn on the vacuum.Without this your stuck with all the dreaded problem of "passive filtration".The trash attaches its self to the charcoal.Use ether to help wash oil through filter.I prefer ether, but alcohol seems to work.Evaporate excess solvent and your left with this Gold to Red Oil with crystals forming on the edges.This is basic organic separation by solvent.-usdi Agaluga
