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 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
(RESULTS: Fine silver.999 = bright red, .925 silver = dark red, .800 silver = brown, .500 silver = green)
