SWIM usually separates the various colors into different piles. Mostly white, mostly off-white, mostly yellow, mostly orange.

This STB batch has some really waxy dark looking stuff!

Is this stuff perfectly usable to make Changa, or should SWIM discard or even rex it with bestine (or re-wash somehow?).

It was made from 1 lbs of MHRB powder, but the 3rd of 4 total extractions was accidentally lost down the drain. So it's not a full extraction. SWIM has yet to weigh it.

I would split it up roughly by purity, give the batches a wash and a re-x or two personally.

Looks like a lot of plant fats in there

how much bark did you use? for that yield

From my expierience even the dark orange goo is perfectly fine to smoke.
So no worries about making changa from it

1 lbs of powdered MHRB. SWIM has yet to weigh it.
