Description Beloved Treasures has sourced a supplier in Europe that manufactures acid testing products. 20ml bottles available are: 8K, 9K, 14K, 18K, 22K, 23K, Silver and Platinum. Please contact us
[email protected] to discuss your needs for large quantities. TESTING INSTRUCTIONS. Press firmly and scratch the item to be tested onto the testing stone, then place half a drop of the closest acid to the karat you estimate the metal to be. If the acid dissolves the metal, the metal is less than the carat displayed on the bottle. Try again with a lower level acid. If it dissolves the metal slowly, it is possible that your metal is gold, just not as pure as the karat rating on the bottle. If the metal stays and does not dissolve, it is AT LEAST the karat of the rating on the bottle you used for the test. Happy testing!
