is silver wire REAL silver?
« on: November 30, 2012, 04:11:55 PM »
I have a decent length of "silver" wire that was used for some craft projects several years ago. They were originally wrapped around some wine glasses and a few platters as decorations.... im not sure if the wire is pure silver...Anyone know how I can find out?

Ive read about the yellow mustard test... but havent tried it yet. Anyone else have experience with this?

I am pretty sure if you coil the wire into a coin sized piece of silver you could easily perform the "Ice Test"

If you take it to any jewelry store that buys scrap gold and silver can easily test it for you.  All the stores I worked at would do it at no charge.  I do recommend stopping buy when they are not busy.  Feb 12 to 14th is a bad time to go too a jewelry store....

According to my crafty girlfriend, wire for jewelry crafts can be one of the following:

Stirling: This is ~92% silver alloyed with other metals to achieve desirable mechanical properties.

Plated: This has a thin silver plating on a cheap base metal like steel.

Silver Filled: This is a very thick (~50% of the wire thickness) coating on a cheap base metal.


I agree with PorcupineKate, see if a jewelry shop can test it for you. If they can't, or if you live out in the sticks, here is what I suggest:

  • Use a magnet to determine if the wire has iron in it.
  • Like Rob_Cleveland said, try the ice test.
  • To be really sure, get ahold of a volt meter, sand the ends of the wire and use resistance measurements to calculate the resistivity of the metal. Compare this to the listed value  for silver
