About Tin
Used since the Bronze Age to make bronze with copper. Tin cans were invented in 1810 for food preservation. Tin pest transforms tin into a crumbly powder below -13C, possibly contributing to Scotts Antarctic expedition failure. Tin whiskers growing from electronic solder have caused satellite failures. The symbol Sn comes from Latin stannum. Cornwall was a major tin source for the Roman Empire.
