Indeed... combining all techniques allow us to make the best extractions ever.

My simple understanding of the process is heat applied to herb breaks down cell walls to release more THC to bind with the Alcohol or Fat. Therefore, if the temperature is not heated anywhere close to the boiling point of Glycerine - why must an airtight container be used? Is there some reaction occurring between the Glycerine and air that I don't understand at 311F? Since Glycerine does not boil until 554F, it should be fine without being airtight.
Dragonrider and others - please give me your thoughts on this.
Well... ive been making experiments with glicerin lately, and ive concluded that to dissolve THC in glicerin is FAR harder than dissolve it in alcohol... thats why the time needed is greater.
Also, glicerin is hygroscopic, what means it absorbes water form the air. And the water interferes the solubility of THC, as it is not soluble in water. I think thats why the container must be airtight.
Maybe some reaction with the air also happen at this temperatures (oxidation by oxigen)... dont know for sure... but its possible. Unfortunately i havent this equipments, or i would try it myself...
