Nova Bronstein - Sometimes curiosity gets the best of you, sidetracking you to follow an irrational thought to a rewarding path ... you hope ... and this was certainly the case last Friday. A friend of mine came to me inquiring about a slim silver-tone bracelet that was given to her. She wanted to know if this lovely present was actually made of silver or not. And I realized that I didn't have an easy answer for her. Determined to remedy this, the two of us set on a quest for practical tests to find out if something is truly silver. 

Test #1: Acid

This test called for Nitric Acid, which, as I'm sure you could guess, we did not have on hand. Just to give it a shot we tried this test, substituting lemon juice instead of the Nitric Acid. The results are supposed to be that for 100 - 90% silver objects, a drop of acid will turn milky in color when it comes in contact with silver. This proved very disappointing. Our results were nearly indistinguishable from a regular drop of water on silver. (Test found here.)

Test #2: Magnets

The next test seemed more promising and ... we hoped ... more conclusive. Only iron-based metals, known as ferrous metals, are magnetic. Therefore, any solid silver item should not react when coming in contact with a magnet. Doing this test, we did get the hoped-for result, getting no magnetic reaction. The problem was that there is something profoundly unsatisfying about a test that results in no response. And, even if the object was made of copper and plated with silver, the outcome of this test would have been the same.

So we were left feeling unconvinced and continued searching for a test which clearly communicated a positive reaction. On to the next test!
