The whole extraction is not a complete flub, but I've probably lost some good product. With our first freeze precipitation the dust actually crashed out but my partner and I didn't have a way to separate the now-clear naptha layer into another container at the time, so some crystal has probably inevitably been caught up in the dust that settled out. However, it is just plant matter, not lye or anything so even if we shrugged and collected the dust as well it should be relatively harmless, no? (The biggest thing I'm worried about would be it throwing off our final numbers for how much actual product we got out of it. I guess we could just collect it separately and do another mini-extraction...)
These final numbers are sometimes misleading. Extractions can be high yielding but with mediocre quality of the final product or the other way round. I personally would rather have a high quality extract with mediocre yield (well, in reality it's impossible, but pure product in awesome yield would still be preferred :D ), since it is more potent per weight, which compensates part of the loss.
If you did a STB procedure you have your rootbark in a strongly alkaline water phase. Therefore that dust soaked up lye solution and may not be totally harmless. You could get rid of it easily via a filtration step before freeze precipitation. If you already ended with crystals you could redissolve them in clean IPA or acetone, filter that solution and evaporate.
Good luck and enjoy the fruits of your work
Oh, to add something totally different: looks like next semester I'll finally have enough time to do those courses over at the pharmacy department I wanted to since 2 years. Yay
