What is it called, I ended up with it trying to make oil, I'd done it a half dozen times and always got oil, the only difference being that time was instead of evaporating the butane in the bowl I poured it onto water to speed up the process.
It's always been a mystery and no ones ever known wtf I'm talking about lol.
I cleaned a oily bowl with ipa in desperate times, I got the oil together but I couldn't smoke it, imagine sticking your joint into ipa... That's how it tasted.
The method I read said that with iso the longer it sits the lower quality it’ll be. I love the brown putty stuff which i had to let it sit for maybe 10 seconds max to get. I tried it just running straight through by putting bud on a screen and pouring iso over it. That ended up the tan keif powder.
Idk how much difference it actually makes but it was fun to mess with.
We used to make it in the late 90s and feel like chemists with our crackly sludge. ha. I'll take it over some of the runny black unpurged BHO I used see people trying to get off.
