It is important to note that precious metals is tested with Nitric Acid. Different acids dissolve different types of
materials. There are many types of acid
and not all types are good for testing your precious
metals. Nitric Acid does not dissolve precious metals in any way.
metals. Nitric Acid does not dissolve precious metals in any way.
Some methods of conductivity and displacement for
testing precious metals leave too
much room for human error. Equipment
failure, calibration and control over the results mechanically leave you
wondering.
When you test precious
metals, the age-old method of the acid test seems to be the test of choice
to most precious metal buyers. Since the test and the precious metal are two
elements, the state of mater for each is static and does not have
variables. Therefore it is a consistent
manor to test precious metals. Very few tests outside of the acid test have
reliability. Since the typical gold seller
is not familiar with the many methods, I would try to stay with a company that
acid tests your precious metals.
When testing with acid, every testing kit comes
with one or more acids varying in potency.
It also comes with a stone for creating a rub from the precious metal to be tested. With the precious metal, you rub an area of
the jewelry/etc. on the stone and it leaves a small line of the metal we call a
rubbing. I like to start with the acid
potency for 14K for gold. In the center
of the gold rub dab a small portion of the 14k acid. If the acid dissolves it is of a lesser karat
value than 14kt gold. You then perform
the same test on the edge of the gold rubbing with the 10kt acid. If it dissolves the gold is not real. If the 14kt acid did not dissolve, then take
the 18kt acid and test another spot on the line. Finally when the gold dissolves with the acid
potency on a gradual increase, the karat value of the gold you are testing is
revealed. If it never dissolves you have
24kt gold.
You've heard the testing methods. What would you prefer to see when you sell gold?
