If it turns black it is coin quality silver and if it turns green it has high amoun ts of copper and therefore is poor quality silver and a gold color means a lot of brass, it means this is a silver plated item. This is not used to differentiate between different qualities of silver. In Example .999 , .925 , .80. For a more accurate test, you must use our #gt41 red color , silver test solution.
