Silver is known for its electrical and thermal conductivity, and its reflectivity.
Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
Silver has long been valued as a precious metal. Silver metal is used in coins.
Other than in currency and as an investment, silver is used in solar panels, water filtration, jewellery, ornaments, high-value tableware and utensils, in electrical contacts and conductors, in specialized mirrors, window coatings, in catalysis of chemical reactions, as a colorant in stained glass and in specialised confectionery. Its compounds are used in photographic and X-ray film. Dilute solutions of silver nitrate and other silver compounds are used as disinfectants, microbiocides, and in medical instruments.
