One of the first metals ever,COOPER
Copper was one of the first metals ever used by mankind. This was due, undoubtedly, to the existence of this metal in its native structure and, accordingly, this led to the replacement of ancient silex of the Neolitic, because of its better conditions.
Wind injection ovens.
In the Middle Ages, the art of extracting copper from its minerals was developed both in England and Western Europe. Ancient procedures were improved even to the building of real wind-injection ovens.
According to its conditions for being combined with other materials, its alloys with zinc have given birth to a large range of brass, being used also alloyed with tin in the phosphoric brass, with zinc and tin together in the red brass, with zinc and nickel in the alpaca, with zinc and silicon in the brass for bells, apart from a lot different complex alloys where you can find it as an element, even in anti-frictions.
Physically understood, brass changes its primary color by altering the percentage of alloy: so the pale yellow we know is due to a relation of 66% and 75% of copper.
One of our main worries is corrosion. This process happens due to different elements in our atmosphere, and attacks brass rather than copper because of its partial component of zinc. Nevertheless, it does not happen with water, which is undangerous to brass, and organic acids as well.
With no doubt at all, what origins brass corrosion in a higher extent is ammonia and its elements, which are always present in the atmosphere of our cities, as well as mercury and its salts, acting with a bigger power.
