I have been given two narrow heavy guage strips of silver metal. I
believe they are either sterling silver or fine silver. I would like
to test the metal to: 1. eliminate the possibility that it is nickle
silver (or whatever); and/or 2. determine if it is fine or sterling
silver. I would like to be able to do this simply, without the use
of acid to make the determination (if possible). Hope all of you
Metal Wizards can assist with this quandry. Thanks, in advance, for
any and all help.
