Silver is known to be one of the first metals known to man and word silver comes from the Anglo-Saxon word “seolfor.” Archaeological evidence suggests that people first discovered and used silver at least 5000 years ago. Silver coins were used as early as seven hundred BC and the Phoenicians used silver bottles to prevent food from spoiling. During ancient Egypt and the medieval period in Europe, silver was considered more valuable than gold.
Silver is in demand for its strength, malleability, electrical and thermal conductivity, and ability to endure extreme temperature ranges. In addition, its sensitivity to and high reflectance of light give it exceptional properties. It is estimated that more than 1,740,000 metric tons of silver have been discovered to date.
Silver is a key material with many uses in our modern world besides its well-known use in ornamental jewelry. The vast majority of silver, over 430 million ounces produced annually, is used for industrial purposes. Jewelry is the second highest use of silver, with over 166 million ounces used annually.
Uses of industrial silver include:
- batteries
- bearings
- electronics
- electroplating
- photography
- medical applications
- mirrors and coatings
- solar energy
- to kill bacteria
- water purification.
