"Tin derives its name from the anglo-saxon word ´tin´. It derives its chemical symbol ´Sn´ from the latin word stannum. The first uses of tin appear to have been in alloys with copper and zinc to make brass and bronze, and can be dated back to about 3,500 BC. It is not known who identified tin as an element and it may have been recognized as something that could not be divided any further, or was elemental, by alchemists and experimenters."
