I'm interested! I've done small-scale precious metal reclamation, also silver castings and home forgings. Basically that makes me an expert ;)

As someone with no knowledge of this, how do you do small-scale precious metal reclamation and how did you get into home smithing?

I built a forge a few years ago with a bucket, plaster of paris, some quartz sand, some iron pipe and a blow dryer. Then I started hammering on steel when it turned red.

Metal reclamation is just chemistry so youtube and grainger are all you really need.
