SILVER TESTING KIT METHOD: This silver testing method is ideally used on material 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 or other finished silver or potentially sterling silver items, be sure to choose an inconspicuous spot so as not to compromise the finish of the item

TESTING FOR SILVER: To test for silver purity and quality, scratch the item onto the thoroughly washed test stone, leaving a visible deposit, then place a small drop of the solution over top of deposit; if the material is of high quality silver, the solution will turn bright red; 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 could potentially be a silver plated item in which case results can vary depending on deposit)

SAFETY NOTE: Testing Solutions can be harmful to the skin. Please exercise the utmost caution when opening and using this product and method of testing! Proper protective eye wear and gloves are highly recommended, as the solution can burn unprotected skin. Read the label on the bottle and follow the included operational instructions.
