History of Alluminium (Not finnished)

Ancient Greeks and Romans used aluminium salts as dyeing mordants and as an anesthetic for dressing wounds. The metal was first produced in 1825 (in an impure form) by Danish physicist and chemist Hans Christian. He reacted anhydrous aluminium chloride with potassium amalgam and yielded a lump of metal looking similar to tin. Friedrich Wohler was aware of these experiments and cited them, but after redoing the experiments of Hans, he concluded that this metal was pure potassium. He conducted a similar experiment in 1827 by mixing anhydrous aluminium chloride with potassium and yielded aluminium. Wohler is generally credited with isolating aluminium, but also Hans can be listed as its discoverer.
