back in the late 1970’s there was a device called a
iso 2 machine. it would use iso or acetone. a deep
pan heated with a 100 watt light bulb in it’s base.
inside was a basket to hold your pot in. on top of that
was a cooling tower. heat would evap then cooling tower
would cool and drip thru your pot into pan. then you
took that basket out and put in a cup to reclaim your
solvent. like a fancy coffee pot of sorts. then you collected
oil from pan. then someone thought what if i do hash
in here. then vola you had hash oil of many colors.
i still got a iso2 machine lol not used it in forever.
anyway that is how most the hash oil was made back then.
