Silver is one of the first metals to be used by humans. It may have
been the first metal to have been smelted from ore. The art of silverwork
dates back to at least as far as the ancient Byzantine, Phoenician,
and Egyptian empires, where it was forged into domestic utensils, jewelry,
buttons, weapons, horse trappings, boxes, and other articles. Unfortunately,
silver's high utility meant that items were often melted down and reformed
into new items, and much of the ancient and even early European silverwork
has been thus lost forever.
The silver tradition was carried over to colonial America, where it
co-existed with the centuries-old hand-hammered craft traditions of
North and South American natives. The mines in Mexico and Peru are still
the highest-producing ones in the world, and the methods of silver jewelry-making
among native peoples remains largely unchanged today.
Its place in Western society has been a bit more dynamic. Its value
as a jewelry and utensil metal made it an early target for ambitious
miners, and the discovery of the Comstock Lode in Nevada in 1859 created
a silver rush that rivaled the Gold Rush. Silver bullion served as an
important reserve metal, backing up the solvency of financial institutions
and the U.S. government itself. Prior the Federal Reserve's assumption
of control of U.S. monetary policy, American currency was stamped with
the words Silver Certificate, meaning it could be traded in for bars,
much like British pounds.
Today most (over 90%) silver is used in industrial applications. Compounds
of silver are used to make mirrors, electrical contacts, dental fillings,
coins, and electroplating. Over 40% of all silver mined in the United
States is used as silver nitrate and silver halide in photographic developing.
The Kodak company is the single largest consumer of silver in the world.
In recent years silver has lost much of its value as a reserve metal
as well as a traded commodity. However, its low price often means it
acts as a leading metal in jewelry fashion--silver craftsmen are free
to experiment with new and innovative designs, which are later duplicated
in more expensive gold and platinum once the "style" is safely established.
Silver is popular among younger people attempting a less formal look
in their accessorizing, and among those who simply find gold and platinum
too old-world and ostentatious. Silver is also the brightest reflector
of any metal (except for liquid mercury) and can be polished to a high
sheen that even platinum can't achieve. In fact, the chemical symbol
for silver, Ag, is derived from the Latin, argentum, meaning "white
and shining."
The finish on silver can be high polished, matte or brushed (rubbed
with an abrasive), satin (a smoother matte), sandblasted (rough matte),
oxidized (chemically blackened), or antiqued (chemically "aged"). Silver
is often said to have a "patina," a worn-looking finish that is achieved
through frequent use and handling, and which is particular to
the wearer's skin chemistry.
In its pure form silver is almost as soft as gold, and is therefore
usually alloyed with copper for strength. Karatage is not marked because
legally anything called "silver" or "sterling silver" is 92.5% pure.
Sometimes silver from south of the border is designated "Mexican silver,"
which runs anywhere from 90% to 99% pure. Purity is really not something
to worry about with silver.
Silver utensils and jewelry do require more maintenance than gold or
platinum, however. While silver does not oxidize in pure air, it does
react with ozone and sulfides, such as hydrogen sulfide, found in the
atmosphere around many industrial cities, forming a black film of silver
sulfide -- the "tarnish." This process is aggravated by heat and moisture.
Tarnish can be removed by any number of commercially available tarnish-removing
solutions, or "dips." However, these chemicals can also damage gemstones
set in the silver, especially oil-treated gems like emeralds. Many companies
sell special dry cloths that polish silver without endangering gemstones.
