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 on to test stone leaving visible deposit, then place a small drop of the acid over deposit; the purity of the silver is approximated depending on the color the solution turns when applied to deposit; if solution turns red that indicates high quality silver; if solution turns blue or green the sample may contain brass or copper; if sample deposit dissolves, or solution turns a dark brown, it may be a base metal
