Hi G.G. The viscosity consideration came to mind after making QWISO and finding if I am patient enough, like 12-24 hours of patience, I can have a rock hard shatter at 70-80° ambient. But this is contingent on how much oil is in the ISO. I use glass baking dishes to evaporate the ISO in and found is the resulting film is from 2.5 grams of final product it will come out hard. If it is in the 3.5 gram range and up it can sit for days and never harden. I assumed the thickness caused retention of some solvent, but I think more is at play. Due to the odor of material that didn't quite harden, that has been in a container overnight, that smelled wonderfully of terpenes, I am guessing there is a period where the ISO is gone, and the material is still soft due to terpenes that leave over the next several hours. This has been interesting as I assumed the non-shatter material was contaminated with solvent, but I am now guessing that is wrong. For one there is nothing to indicate a solvent when I vaporize it, I use the Seego V-Hit B. Secondly the taste is much better when I don't go for the rock hard shatter. I do try to vaporize rather than burn the material, at 4.5 watts.
The old material was made with a low temperature ethanol soxhet reflux. A 30 gallon steel container, heated with a 200 watt incadescent bulb for heat, damp towels on the top to provide a cooler condensation surface. I processed leaves and small buds. The resulting material was a very thick tar that nearly filled a Gerber baby food jar. I was just copying the Isomerizer methodology that was available in the late 60s to early 70's. When I had access to a lab through employment, I could do a hexane seperation and isomerize it with sulfuric acid, in reverse order than what I just stated.
I'm going to fine tune my QWISO process and see if I can consistently find a sweet spot between the solvent being gone and more terpenes being present. I am guessing that buds will ND because of the surface area, and the small size of the trichromes, whereas my tar was 1-1.5 inches thick, and it was definitely sticky, just like asphalt tar.
Hope I answered your questions, LMK if I didn't. No coffee yet, waiting for water to boil. Thanks for sharing, it seems like this whole thing should have been 'hashed' out years ago. If we only had cheap, easy access to a GC to test the material at each step so we could get away from our subjective guessing.
