Did you know? Until 1886, aluminum was considered a rare metal and a chemical curiosity. Researchers in the U.S. discovered the continuous electrolytic reduction process which is used to make aluminum metal from the aluminum ore, bauxite. Exactly why you won't dig up any 19th Century relics made from aluminum (including our most repulsed invention: pop-tops)!
