I have a friend who is doing an extraction STB with 100g MHRB. It came pre powdered and he used, 100g MHRB, 100g lye, about 1750ml (purified) water. this tek was used.
TEK he followed it to the letter, but upon pulling the naptha it remained completely clear. even after 35+ hours in the freezer there are no crystals. He is too proud to ask for help but i dont want him to just eyeball it and try again without any help. also, the naptha was in a jar that was kept CAPPED. if you have any suggestions please let me know!
