Predaceous Stink Bug
I've searched around the net and haven't found too much information for extracting silver from old photo negatives. I have found that in some cases a cyanide solution is used, which I'm not interested in playing with...
I've also read that the average extraction rate is 9 g / kg of negative.
Does one of my PM friends have a safer method for extracting silver from old negatives?
Thanks!
