{"product_id":"platinum-testing-acid-solution","title":"Platinum Testing Solution-Ships Ground Only","description":"\u003cp\u003ePlatinum Testing Acid Solution is a specially formulated chemical solution designed to test for the presence of platinum in metal samples. Each small plastic bottle contains approximately one ounce of platinum testing acid. Testing precious metals with acid is an acquired skill — results are subjective and developed through experience and repetition. Always wear eye protection and rubber gloves when handling testing acids, and keep a cloth on hand for cleanup. The acid can stain skin and cause serious injury; handle with extreme care and keep away from eyes.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSpecially formulated platinum testing acid solution\u003c\/li\u003e\n  \u003cli\u003eApproximately one ounce of solution per plastic bottle\u003c\/li\u003e\n  \u003cli\u003ePlatinum samples should remain intact and not dissolve under the platinum acid; note that 800-type platinum may dissolve slightly\u003c\/li\u003e\n  \u003cli\u003eCan also be used for comparison testing of gold and silver when used alongside appropriate karat acids and a test stone\u003c\/li\u003e\n  \u003cli\u003eCompatible testing method: rub metal onto a test stone, apply a small drop of acid, and observe the reaction\u003c\/li\u003e\n  \u003cli\u003eFor best results, compare reaction against a known sample using test needles or confirmed karat pieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTesting Reference Guide\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePlatinum:\u003c\/strong\u003e Should stay and not dissolve under platinum acid.
