Period 5 element other metal is not easily oxidized in air and is used to coat other metals to prevent corrosion. The firstalloy, used in large scale since 3000 BC, was bronze, an alloy of tin and copper. After 600 BC pure metallic tin was produced. Pewter, which is an alloy of 85–90% tin with the remainder commonly consisting of copper, antimony and lead, was used for tableware from the Bronze Age until the 20th century. In modern times tin is used in many alloys, most notably tin/lead soft solders, typically containing 60% or more of tin. Another large application for tin is
Sundown Tin and Copper Mine the slag was cast into sand moulds, typical of reverberatory furnace practice. East of the furnace are a number of sleepers, lengths of wire cable, and the base of the structure which could be the flying fox used to bring tin and copper ore to the mill site. However, this area of the site has been extensively disturbed by more recent bulldozing and earth moving activities. The two dams are located below the Old Works site, and are earthen dams, riveted with timber on the downstream side, and both are broken. A large amount of tailings sand lines the creek
