Use

Among the first uses of gold are religious and cultural, as it became many decorations and idols for thousands of years. The next major use of gold was as the first monetary systems, representing wealth and gradually replacing the barter system until the advent of modern economics. Gold has found many industrial uses because of its excellent electrical and thermal conductivity properties. It is used for plating other metals and as an alloying metal. It is used in themanufacture of jewelry, dental inlays, art, currency, and electronic components, and in some medical devices to provide radio opacity. Gold compounds have also found use in medicine in the treatment of certain cancers, rheumatoid arthritis, and discoid lupus (a rare skin disease), and in specialized surgical procedures.
