I did do a search but didn't find anything but AR condensing for jewelry, so my question is this:
Do I need to add nitric as it condenses so that the gold does not come out of solution? Or did something else cause it to come out? And this is what happened:
Couple days ago I wanted to condense a batch of AR which didn't contain that much gold - or so I thought. I decided to let it sit on medium heat until it condensed by half. Took about 8 hours. When I was done I found a billion little gold sparkles like someone dumped ultra-fine gold glitter in the condensed AR which I think at this point was just muratic acid. The gold particles were ultra-clean shiny gold. I've never produced such clean gold from any AR drop. Maybe I should forget SMB and just remove all nitric? It's really, really clean looking gold.
