Sterling or Fine Silver?
Does anyone know how to tell the difference between sterling silver &
fine silver? I have a bunch of sheet & wire that's pretty old, with fine & sterling silver mixed. Is there a heating/color change/soldering type trick to tell which is which? Much Thanks! |

If you heat it in an oxidizing atmosphere the Copper in the Sterling will
oxidize and turn black. If you then dunk the heated section into a pickle soln. it will brighten back up. If you heat Fine Silver it doesn't blacken at the lower temperature required for Sterling's Copper to oxidize. -- Don Thompson "The bravest are surely those who have the clearest vision of what is before them, glory and danger alike, and notwithstanding go out to meet it."- Thucydides "Men are never really willing to die except for the sake of Freedom: Therefore they do not believe in dying completely."- Albert Camus "Jenny" wrote in message ...

Sterling silver stays a little bit harder alfter they were both glued. -- Heinrich Butschal casting technologies http://butschal.de/werkstatt |
