Later, in 1617, the German Georg Engelhardt von Löhneyss (1552–1622) used the term "zinc" for describing the production process of Rammelsberg—Germany ore (Sinclair 2005; Habashi 2018). In 1805, it was discovered in Sheffield, England, that sheet metal could be produced by annealing Zn at 100–105 °C.
