Aluminium

Aluminium is a metal that is silvery white in colour is the most common metallic element in the Earth's crust. It is named from the Latin Alumen by the discoverer of its pure form in the 19th century and has been given the atomic symbol Al.

When aluminium oxides it produces a powder coating on the surface of the metal. Due to mild toxicity it is not recommended for cookware.

It is difficult to extract from its ore (bauxite) and thus was not used during the middle ages. However, aluminium salts were used as mordants by the Greeks and the Romans.

In the SCA is used for making some forms of armour.
