so just as a final check befor my first extraction, i was just thinking id write down the method. if anyone has any suggested additions, corrections or more effective ideas; they are very welcome.
my extraction will be STB. a huge thank you goes out to lazyman and Noman, your teks have been invaluable. as im sure you'l see.

ingredience:
200g mimosa hostillis.
200g sodium hydroxide.
3L distilled water.
naptha.
carbonate is necessary.

method:
mix 200g bark with hydroxide. leave for 30 mins.
add 3L distlled water. rest for 90 mins.
add 150 ml naptha. wait to seperate.
extract naptha and add into seperate container. place container in fridge for few hours.
then freezer for 10+.
repeat naptha wash 2-3 more times.

so yeah...pretty much the Nomans tek to a t. i feel like only taking it to a sodium carbonate wash if the naptha seems unclean in some sort. so as a final check, is everything in order then nexians?
for the record, you lot have been incredibly helpful, thanks alot.
