noman.. does it have to be isopropyl or can ethanol also be used?my friend doesn't really need it to be pure crystals. he would be very happy about getting something amber colored. he doesn't trust black extracts.he unfortunatly used a silver spoon to stir the solution once. after he took the spoon out of the solution it was shiny silver. before it was darkish oxidized silver. he thought he had used a stainless steel spoon until he pulled it out of the solution.if he hadn't used the silver spoon he wouldn't have bothered purifying it further. he is afraid that some oxidized silver might be in there. that would surely not be healthy if smoked!thanks a lot!
