Nikhil User ID: 39883889 India 05/15/2013 01:06 PM Report Abusive Post Report Copyright Violation | Aluminium production process has been developed and known to Indians much before 1820 (infact it is 5 to 10 thousand years old process).. which is the time when rest of the world was also able to produce that. Uptil 1820 world was dependant on India for aluminium requirement. You can refer to the ancient Indian texts where the process has also been elaborated. Noone is getting a pickaxe head from this??? Quoting: Anonymous Coward 15091263 I mean wtf...where is society going... The fact this piece exists at all is a real mystery 400 years old or 18,000 years old it is still something that should not exist. Even if it just 400 years old like first thought there is no way it is a pick axe, aluminum was worth more than gold because they had no way to produce it, the Hall-heroult processes was first used in the 1880's. The first "aluminum" EVER produced was in the 1820's that we know of. The metal was first produced in 1825 in an impure form by Danish physicist and chemist Hans Christian Ørsted. He reacted anhydrous aluminium chloride with potassium amalgam, yielding a lump of metal looking similar to tin.[45] Friedrich Wöhler was aware of these experiments and cited them, but after redoing the experiments of Ørsted 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.[45] Wöhler is generally credited with isolating aluminium (Latin alumen, alum), but also Ørsted can be listed as its discoverer.[46] Further, Pierre Berthier discovered aluminium in bauxite ore and successfully extracted it.[47] Frenchman Henri Etienne Sainte-Claire Deville improved Wöhler's method in 1846, and described his improvements in a book in 1859, chief among these being the substitution of sodium for the considerably more expensive potassium.[48] Deville likely also conceived the idea of the electrolysis of aluminium oxide dissolved in cryolite; Charles Martin Hall and Paul Héroult might have developed the more practical process after Deville. Before the Hall-Héroult process was developed in the late 1880s, aluminium was exceedingly difficult to extract from its various ores. This made pure aluminium more valuable than gold.[49] Bars of aluminium were exhibited at the Exposition Universelle of 1855.[50] Napoleon III, Emperor of France, is reputed to have given a banquet where the most honoured guests were given aluminium utensils, while the others made do with gold.51][52] Aluminium was selected as the material to be used for the 100 ounce (2.8 kg) capstone of the Washington Monument in 1884, a time when one ounce (30 grams) cost the daily wage of a common worker on the project;[53] The capstone, which was set in place on December 6, 1884, in an elaborate dedication ceremony, was the largest single piece of aluminium cast at the time, when aluminium was as expensive as silver [link to en.wikipedia.org] |

User ID: 85273136 United States 04/25/2023 08:36 PM Report Abusive Post Report Copyright Violation | Some scholars are convinced an ancient, advanced civilization existed where the nation of India is today. They claim the prehistoric city-state had advanced technology including high-energy weapons, jet-like aircraft, and even the atomic bomb. Quoting: NiNzrez Now a stunning artifact has been identified by some researchers as the part of an aircraft landing assembly dated as old as 20,000 years made from a metal that wasn’t discovered until the early 1800s.
