It's Elemental

Archaeological evidence suggests that people have been using silver for at least 5000 years. Silver can be obtained from pure deposits, from silver ores such as argentite (Ag₂S) and horn silver (AgCl), and in conjunction with deposits of ores containing lead, gold or copper.

Silver and silver compounds have many uses. Pure silver is the best conductor of heat and electricity of all known metals, so it is sometimes used in making solder, electrical contacts and printed circuit boards. Silver is also the best reflector of visible light known, but silver mirrors must be given a protective coating to prevent them from tarnishing. Silver has also been used to create coins, although today other metals are typically used in its place. Sterling silver, an alloy containing 92.5% silver, is used to make silverware, jewelry and other decorative items. High capacity batteries can be made with silver and zinc and silver and cadmium. Silver nitrate (AgNO₃) is light sensitive and is used to make photographic films and papers. Silver iodide (AgI) is used to seed clouds to produce rain.
