Silver Testing Acid (Clear)
Product Details
BRAND: JSP
INSTRUCTIONS: If the test spot turns a creamy color it is high quality silver, usually sterling. If it turns black it is coin quality silver and if it turns green it has high amounts 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.
