i tried the subzero method for my virgin voyage and you can just call me titanic. Everything went wrong after my plastic wire bag dissolved and the Oklahoma winds started blowing. Needless to say; I ended up filtering the acid about 15 times to avoid any contaminants in my pure gold. I did keep all coffee filters after rinsing them in a jar of distilled water which i also kept (of course) but the urea never fizzed and i added the precipitant which went to brown as expected but now real mud and now its stuck there. It never went to the clear color described. Help me someone please, I am about as low as I can be at this point. I am desperate! Where's me gold? ARRRR!!
