So the way gold karat is tested at home is with these small squeeze bottles of testing solutions. To test your gold you polish a bit of gold off the item, then drop different the different solutions on the gold dust. When the gold gets darker, you got a hint on the karat, depending on the solution that turned it dark.
Now my question is, does anyone know what these solutions contain? They mostly come in kits for testing "10K, 14K, 18K, 22K" this one.
I am mostly interested in the gold tests, not the platinum and silver, however these might be useful too. Seem to contain nitric acid for the 10 and 14K, and nitric+HCl in the 18 and 22K. Does anyone know the concentration for these, as it seem like a ripoff to BUY these instead of making them myself. :lol:
