It appears that you and I often are at odds over some matters, but I happen to agree with you on this one. I have no clue why excess nitric would discolor melted silver--but impure silver would certainly take on a fire coat, as is represented in the posted picture.spaceships said:No answer to my question? Well 24 hours later here's my take in the theory posited of excess Nitric.
Any excess Nitric will be used up by dissolving copper prior to cementing the silver. Copper isn't going to cement copper out into the silver unless electricity is involved (as in a copper cell) so gentlemen respectfully I disagree with your theory of excess Nitric.
I'm open to be called out as wrong so feel free 8)
Depends. If what you melted was silver cement, recovered on scrap copper, and you didn't use fine wire, whereby you may have left behind lots of partially consumed bits of copper, the material shown may be a good candidate for the silver cell. However, I'm troubled by the amount of fire coat I see. If you had melted the material in a crucible, along with some borax, it would most likely have removed the vast majority of the oxides, leaving behind a much cleaner silver.GotTheBug said:Would it be okay to run this in the cell or shoud I start over, wash the dropped powder better, and remelt?
