* This metal's Latin name is "ferrum" and it is a magnetic, malleable and silvery-white metal. In its metallic form it was used to make ornaments and weapons in prehistoric ages. When exposed to moist air, it oxidises and tarnishes to form a moist reddish-brown oxide, better known as "rust".
* It has the symbol 'Mn' and is principally used in making alloys, as by itself, it is rather brittle. It does not occur in the free state, except, rather strangely, on meteors. Its principal ore is pyrolusite, which is mined is large quantities in Ukraine, Georgia and South Africa.
