Aluminium (or aluminum) metal is very rare in native form, and the process to refine it from ores is complex, so for most of human history it was unknown. However, the compound alum has been known since the 5th century BCE and was used extensively by the ancients for dyeing. During the Middle Ages, its use for dyeing made it a commodity of international commerce. Renaissancescientists believed that alum wa

In 1808, the British chemist Sir Humphry Davy confirmed the existence of alum and named the substance to Alumium (later changed to Aluminum). In 1825, Danish chemist and physicist Hans Christian Ørsted began experimenting about aluminum extraction.
