The first iron to be used was probably an alloy of Iron (Fe) and Nickel (Ni) which when it was heated, probably by accident, it could be bent and therefore be used to make arrows and tools. It was in the II century when the first furnaces for the treatment of minerals containing iron were constructed, but the installations were primitive and did not produce a high enough temperature to melt
