History
Silver and silver mining became part of human history around 4000 BCE. Because of its luster and malleability, it was readily adopted as a popular form of currency and also used to make ornamental decorations. However, as pure silver was too soft to be used for durable goods, silversmiths learned to combine pure silver with other metals to create a silver alloy that was more resilient than pure silver, but that still had the same sheen. The most prominent silver alloy is sterling silver, which consists of 92.5 percent pure silver and 7.5 percent other metals (copper being the most frequently used).
Common Uses for Sterling Silver
Although silver is used in a wide variety of industries, including electronics, photography and medical, sterling silver is used predominantly for its aesthetic appeal. Only about one-third of all silver produced is used for the more traditional items, such as jewelry, flatware, household accessories and coins. Sterling silver jewelry and flatware is easy to identify as it will be stamped with either '925," "ster" or "sterling."
Caring for Sterling Silver
Because sterling silver is a mixture of silver and other metals, sterling silver will tarnish. The tarnish appears in the form of darker or black areas on the silver. To prevent tarnishing, store sterling silver pieces in specially treated bags that help to slow down the tarnish process. If the tarnishing has already occurred, sterling silver cleaning cloths are available at most jewelry stores. Gently rubbing sterling silver with a clean, dry cloth will also help to remove less severe tarnish. Keep any sterling silver pieces away from harsh chemicals.
Advantages and Disadvantages
Sterling silver is very versatile in its applications and as such, it is a very desirable product. Because of sterling silver's malleable nature, it can be used to create very intricate pieces. However, its softness also increases the chances that the metal will be scratched or otherwise damaged. Sterling silver jewelry is very affordable, but sterling silver flatware can be quite expensive. And, while the tarnish that accumulates on sterling silver is easy to remove, the metal will need extra care to prevent or eliminate tarnish.
Testing Sterling Silver
Rarely, pieces stamped as sterling silver may not actually be 92.5 percent pure silver. To test a piece in question, find an inconspicuous spot on the metal and slightly scuff it. Apply a small amount of nitric acid to the spot. If the metal is made of a silver alloy that is less than 92.5 percent pure silver, the nitric acid will turn green or black. If the metal is sterling silver, the nitric acid will become a cream color.
