Silver, like gold, has been linked since ancient times to religion, coin, and trade. Silversmithing is one of the world’s oldest trades. Silver ornaments, ceremonial vessels, and decorations have played important parts in the religious and spiritual traditions of many civilizations, both ancient and modern. Decorated silver pieces, some 6,000 years old, have been found in ancient Egyptian tombs, where silver was prized over gold because of the difficulty involved in mining the metal. To the Incas, silver was a precious commodity and represented the “tears of the moon.”
The religious beliefs, superstitions, and folklore of many peoples from around the world are peppered with references to silver, a symbol for goodness, purity, and luxury. Spiritual and New Age traditions attribute special cleansing and healing powers to silver.
Silver (chemical symbol Ag) is not as rare as gold or platinum, a fact that is reflected by its price in world commodity markets. Silver is one of the most reflective metals. When it is polished, it reflects more than 90 percent of visible light back to the eye. For this reason, it is often used to mount transparent stones in jewelry because its high reflectivity increases the sparkle of the stones.
Like gold and platinum, silver does not react with most chemicals, will not rust or corrode, and is relatively durable. It does react with hydrogen sulfide, an atmospheric pollutant, which causes a gray surface film, called tarnish . The tarnish on a piece of silver can be easily removed with special polishes.
Silver is also extremely malleable and ductile. It can easily be drawn into a thin wire or hammered into new shapes. When silver is worked, the stress of the pounding can make the metal brittle and prone to fracture. Silversmiths solve this problem by periodically annealing or heating the metal to restore its malleability. Silver objects can be finished with a variety of decorative patterns and textures.
Silver is the world’s best conductor of heat and electricity. In fact, it is used as the standard by which the conductivity of all other metals is tested. For this reason, silver is commonly used in many industrial and medical applications.
