Zgodovina
Copper occurs naturally as native copper and was known to some of the oldest civilizations on record.

Earliest estimates of the discovery of copper suggest around 9000 BC in the Middle East.

It was one of the most important materials to humans throughout the copper and bronze ages.

Applications
Copper is often used for electrical wiring applications and for household plumbing applications.

Copper sulfate is used as a fungicide and as an algicide in rivers, lakes and ponds.

It is also used in cookware and cooking utensils.

Commercially important alloys such as brass and bronze are made with copper and other metals.
Cooking acidic food in copper pots can cause toxicity
