I was having a conversation with a friend about desoldering fumes and that we should probably be wearing reusable respirators because of the heavy metals from the fumes. We stumbled on a dental amalgam page regarding sources of heavy metals, how amalgams are a source of mercury, then he said... imagine if it's possible desoldering amalgams... I said probably not but I am curious. Neither of us have amalgams to test it out but hypothetically... Would it be possible to melt an amalgam with a soldering iron while taking into consideration the high melting point of the metals in the amalgam?
