SILVER TESTING KIT METHOD: This silver testing method is best used on silver that is yet to be smelted, due to the harsh nature of the solution that could potentially damage an already finished item; if testing fine jewelry, sterling silver items or other finished items, be sure to choose an inconspicuous spot so as not to compromise the finished piece

HOW THE SILVER TESTING KIT WORKS: To test silver purity, scratch the item onto the test stone leaving a visible deposit, then place a small drop of the solution over top of deposit; the purity of the silver is approximated according to the color the solution turns when it is applied to the sample; if the solution turns bright red that indicates high quality silver; if the solution turns blue or green the sample may contain brass or copper; if the sample deposit dissolves quickly, or the solution turns a dark brown or yellow, it is likely a base metal or silver plated
