material and it is part of many metal alloys. Due to the fact that Copper does not react with water‚ it makes it very useful for plumbing. Copper has been known since prehistoric time. It has been mined for more than 5000 years. Copper has a melting point of 1083.4 +/- 0.2°C and a boiling point of 2567°C. It is second only to silver as an electrical conductor. In addition to many other uses‚ copper is used in for cookware. Brass and bronze are two important copper alloys. Copper (I) burns blue in a flame
