Lol..sorry Rae..hehe..
I'm speaking of creating a device that makes hash oil, with N-butane as the solvent.
The problem with traditional column extractions(loading material into a tube, and spraying cans of butane through the tube with a filter at the opposite end) is the solvent is completely wasted and evaporates away very quickly as it is a gas in it's natural state.
The device will allow one to” recover” that butane, using both hot and cold tanks, allow the butane to be retained for recycling purposes.
The thingy will also allow the plant material (trim/buds) to soak for a while, pulling more goodies out.
