Question about your technique.
disolving dirty extract in butane inside bottle, chill to no pressure, and add cold water? like a hexane wash but with the butane? let seperate, freeze water? or buchner filter or whatever? I never see anything about the process with butane just the hexane and salt water.... who cares about the .04% or whatever that the butane can pick up that the hexane can't?
