This is my thought on it. My qwiso is on point, but something different is always a plus. I'll be running some nugs through the wife's straightener with the next harvest in December.
ADT, do you just let your material sit in the ISO or do you lightly shake? I usually do 3 runs of medium shaking for 30 secs with 99.8% ISO. Leaves a dark amber qwiso shatter with some small piles of oil.
I'll do three runs, no shaking, maybe a little swirling. I let it sit in the freezer as well.
I'll put my timer on, first run is 45 seconds, second is 5 minutes, the third is 10 to 15 minutes. Anything after that long is green/dark/low potency/no taste.
The first two runs will look very orange/amber, crystal clear, and stable shatter that you can pick up and break off your chunks and won't melt in your hands. The third run is a little darker, so it's about when it starts leeching cholorphyll, but potency is still there, but it's not near as smooth or tasty as the first two runs.
I just let them sit outside for 24 hours and run a fan over them, scrape it up and ready to dab. No heat added so taste is great. When I initially scrape it's all a fine, almost white colored, powder. I simply press it together between my fingers for a little bit with some parchment paper to bond it all together to get that rock hard lovely looking shatter.
