I used to set my jars on a towel that rests on a dry ice block and I would get a good clean crash of fats and no visible oil. Or so I thought…Unfortunately the fact is it would take a considerable volume of butane to selectively reject “fats” and not thc
I recently got my samples lab tested and the results were consistent with the idea that butane (non polar) will reject the thc when chilled to cryo levels.
I set aside my crude and terpene fraction
Crude: Verify | CWLIMS
Terps: Verify | CWLIMS
The crude was decarbed for production prior to testing.
