   Pure aluminium is a silvery-white metal with many desirable characteristics. It is light, nontoxic (as the metal), nonmagnetic and nonsparking. It is somewhat decorative. It is easily formed, machined, and cast. Pure aluminium is soft and lacks strength, but alloys with small amounts of copper, magnesium, silicon, manganese, and other elements have very useful properties. Aluminium is an abundant element in the earth's crust, but it is not found free in nature. The Bayer process is used to refine aluminium from bauxite, an aluminium ore. Aluminium is one of the elements which as alum or alumen, KAl(SO₄)₂, has an alchemical symbol (the symbol to the right  shows Scheele's symbol, alchemy is an ancient pursuit concerned with, for instance, the transformation of other metals into gold). Aluminium was first isolated by Hans Christian Oersted in 1825 who reacted aluminium chloride (AlCl₃) with potassium amalgam (an alloy of potassium and mercury). Heating the resulting aluminium amalgam under reduced pressure caused the mercury to boil away leaving an impure sample of aluminium metal.
