What can you make with copper?
Copper is a relatively soft metal that is most commonly used for electrical wires due to it excellent conductivity. Silver is a better conductor but copper is cheap. Copper is extremely ductile which means it can be drawn into long wires. Copper can also be used to dilute other metals. It is commonly mixed with gold to make the gold harder and more durable. Rose gold is gold that has had copper added to it. Two common alloys of copper are bronze (mainly copper and tin) and brass (mainly copper and zinc). Both these alloys are stronger than the original copper but retain some of its wonderful colour. These alloys are used to make wonderful decorative items such as trays, boat and bathroom fittings and jewellery. Gold money is gets is colour these days from copper rather than gold.
