hey napp
this is kind of a late response as I forgot to add this to my watched list, and just decided to look it up 
my final yeild was about 1.2 grams to bring me up to a %1.2 the spice in the last 3 pulls was mild yellow, but still dried out nicely.
since then, I completed another extraction on 350g MHRB, which are the remainders of the pound I bought.
my extraction went as follows.
350g MHRB
350g Lye
10L HDPE windsheild washer container, thoroughly cleaned.
200 ml naphtha per pull, 400ml total(1st pull is reused while 2nd pull is freeze precip'ing, etc..)
I don't remember the yield of each pull, but final dry weight was about 3.3g to bring me to a 0.94%.
the nexus made this all happen, without you guys never would have made it this far
Thanks nexus!
happy travels
