hard to recover the residue...didn't do too much for the test buds that got soaked. i have found that when the butane evaporates a bubbly looking film is left behind that is somewhat hard to gather. using isopropyl alcohol i rinsed the collection vessel and evaporated a second time. the resulting brown goo can be scraped up and enjoyed. i think higher quality stuff would yield entirely different results.
scooterjay Reviewed by scooterjay on . butane extraction did the butane thing today, made an extraction column out of an old turkey baster and a wire coathanger to hold it. 1/4 oz. of chopped seedy weedy buds were packed in and a test bud was placed in the collection vessle to hopefully become supercharged. put a can of ronson thru, collected the runoff in a pyrex cup (with the sacrificial bud in it) and let it gas off. i have now a bud that is super sticky and a fine resin that is milky white to play with. i tried a little and it is different. more Rating: 5
