Ancient use
Late Roman brass bucket – the HemmoorerEimer from Warstade,
Germany, second to third century AD
Various isolated examples of the use of impure zinc in ancient
times have been discovered. Zinc ores were used to make the
zinc–copper alloybrass thousands of years prior to the discovery of
zinc as a separate element. Judean brass from the 14th to 10th
centuries BC contains 23% zinc.
Knowledge of how to produce brass spread to Ancient Greece by the
7th century BC, but few varieties were made. Ornaments made of
alloyscontaining 80–90% zinc, with lead, iron, antimony, and other
metals making up the remainder, have been found that are 2,500
years old.[18] A possibly prehistoric statuette containing 87.5%
zinc was found in a Dacian archaeological site.
