Bismuth


Bismuth was probably not recognized as a specific metal by the early Orientals, Greeks or Romans, but by the Middle Ages, Europeans were becoming aware of its specific nature, and in the 15th Century Basil Valentine referred to it as wismut. The early mineralogist Georgus Agricola, at the end of the 16th Century, latinized wismuth to bisemutum. Only in the middle of the 18th Century, through the research of J. Pott, C. Geoffroy and T. Bergma, was bismuth definitely recognized as a specific metal.
