3 ALUMINIUM Adorned with rubies and sapphires from the Mogok mines of Burma this Shan woman prepares her food. These jewels and the common clay of her ornate bowl are but a few of the many minerals containing aluminium Though first isolated in 1826, i was not until 1886 that its production became commercially practicable. Most of the world $ aluminium is now produced by dissolving an ore named bauxite in molten ayolite, 4 mineral obtained from Greenland, and passing an electric current through the solution. In combination with other metals such as magnesium or copper, aluminium forms Ight allys; some of which; though only about one third of the weight of steel are just as strong and do not rust. The famous statue of Eros in Piccadilly Circus; one of the earliest large aluminium castings, shows no signs of corrosion after 40 Years of exposure to London smoke. One of the largest factories producing wrought aluminium and its allye in the form of sheet; strip, and extrusions is the LCL works at Waunarlwydd in South Wales: These go to belp m tho production of all manner of finished articles from saucepans to aeroplanes; scaffolding poles to ashtrays, motor e5 parts to egg cups ICL AIPERIAL CHEMICAL INDUSTRIES (NZ) LTD: False teeth?
