Here in Nor cal we call co2 extracted oil Gold dust oil. I'm sure the idea was mimicked from the micro brewing industry as super critical fluid extractions have long been done on hops as i've been told.
The final product Gold Dust would liquify at room temperature, and was around 70% pure.
If this be yer quest maitee, go read Cannabis Alchemy and learn a much better way to soar past 70% pure.
