The history of aluminium industry

Humankind came across aluminium long before the metal we know today was produced. The Natural History by Pliny the Elder, a Roman scientist, told the story of a first century craftsman presenting a cup made of an unknown metal looking like silver, but too light to be sliver, to Tiberius, the Roman Emperor. Alum, an aluminium-based salt, was used extensively in ancient times.
