Platinum test acid is used to determine the platinum purity of articles being tested. Scratch or rub the metal onto the testing stone and apply a drop of acid. If the material on the stone is platinum, it should keep its white, bright color. Platinum test acid can also be used for 18k and 14K white gold. In the case of 18K, the material on the stone should start changing to a light bronze color in about 3 minutes. For 14K white gold, the material on the stone should disappear in about 15 seconds. Test acids come in sturdy plastic bottles to maximize safety yet allow the user to easily squeeze out a drop at a time. Note: This product cannot be shipped internationally.
Size: 12 grams
