Description Platinum testing acid 2 bottles. Is your Platinum genuine? Each 20ml bottle comes sealed and contains enough acid for hundreds of tests. The bottles are designed to easily dispense one drop at a time. TESTING INSTRUCTIONS. Holding the piece firmly scratch a 1" line on the stone leaving Platinum behind (you will need a testing stone). Drip a single drop of Platinum testing solution directly onto the scratched off material and wait a few seconds for reaction. If the line does not change colour, it is Platinum. If the line turns red it is possibly Palladium. Happy testing ! To order a testing stone click on this link gold-silver-testing-stone. To order a full kit click on this link gold-testing-kit
