17-08-2020  The use of tin as a coating for other metals also has ancient historical roots, with tinned copper vessels for cooking tracing back to Roman times. Most important was the development of tinning iron sheet in order to form tinplate. This began in central Europe in the 14th and 15th centuries and gradually spread throughout the continent.

Tin - Wikipedia

Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like indium, is soft enough to be cut without much force. When a bar of tin is bent, the so-called “tin cry” can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and frozen mercury.
