Gold Testing Solutions Kit 10k 14k 18k 22k Scratch Stone
COMPLETE ACID TESTING KIT: Easily test the karat content of gold, as well as the purity of silver and platinum, with ToolTreaux’s Complete Acid Testing Kit.
The kit includes six, 0.5oz shatterproof plastic squeeze bottles and one testing stone.
the testing solutions are potent, effective and will see you through hundreds of tests!.
ACID TESTING SOLUTION METHOD: This acid testing method is ideally used on unfinished gold, silver and platinum pieces, due to the harsh nature of the solution that could potentially damage an already finished item.
however, if testing fine jewelry or other finished items, choose an inconspicuous spot so as not to compromise finishing.
HOW TO USE THE ACID TESTING KIT: To test for karat content or purity, scratch the item on to the test stone leaving a visible deposit and place a small drop of the acid over top of deposit.
if gold is the same karat or higher the deposit will not be affected.
if the deposit is of lower karat, the deposit will dissolve.
for platinum and silver repeat the same process.
if the material is platinum, the deposit will not be affected.
if silver material is of high quality, the solution will turn red.
SPECIFICATIONS: Testing Stone Dimensions: 2 x 1.5 x 0.25 inches.
