had not only been hammered‚ but annealed as well (Tylecote‚ 1976). Together with lead and tin‚ copper was one of the first metals to be smelted. With 1084 degrees Celsius it has a relatively low melting point; for annealing 800 degrees are needed. Iron‚ by comparison‚ has a melting point of 1538 degrees Celsius. Its low melting point makes copper easy to smelt‚ cast‚ and remelt without special furnaces or a heavy investment of fuel. Another advantage of copper is that it can be recycled without any
