How to Identify Silver?


There are two easy ways to determine if a shiny metal is silver. Both methods require a chemical reaction to occur on the surface of the substance and then a visual inspection for the presence of silver sulphide (a black stain on the metal). This first method requires that the tester apply a very small amount of French’s brand yellow mustard to the surface of the shiny metal. Ideally, the mustard drop should then be heated, either in the sun or with a cigarette lighter. When heated the volatile sulphur molecule will ALWAYS combine with pure silver to make the dark black stain known as silver. First take a match and press it against the metal surface to be tested. Keeping your fingers as far away as possible, light the first match with a second match. The sulphur is extremely hot as it combusts and it will certainly combine with pure silver when ignited in this fashion.
