I personally dont think butane makes tokes harsh. ive smoked
severely underpurged ronson BHO on purpose a few weeks ago to see if ronson butane gave it funny tastes, and it wasnt any harsher than the average oil. I think 95% of the burn is plant waxes that come from not winterizing. my wax is def harsher than the shatter though, and way less tasty
.I notice a difference
I dont understand how your oil lightens as it turns to wax... everyone elses (I think), especially mine, seem to darken to the extreme as it waxes. was it very fresh material? or a possibly 90% sativa plant? ive noticed that my kush, which I think is a strong indica, is always very very dark.
fluke
so... what if you took a gram of that "dried" wax, put it in a dish, and mixed, flattened, whipped, stirred, etc.. it up... it would no longer resemble a dried chunk of wax... but it turns into a sticky, liquid (kinda) form.. why is that? what if you took that sticky liquid, whipped wax stuff, and put it into the chamber and made it was up AGAIN?? hmm.. food for thought
mine gets powdery, then if i press it, it goes back to wax form.... it doesn't get liquidy at all, this is what i do with all the little crumbs left over from my wax
