Vanadium can be hammered and stretched
without breaking. This hard, strong metal is
easy to shape. Vanadium was first purified
in 1869 by the British chemist Henry Roscoe.
Today, it is commonly extracted from its ore
vanadinite. Ancient metalworkers used tiny

amounts of vanadium compounds to make a
very tough substance called Damascus Steel.
This was named after the capital city of Syria,
where ironworkers made the world’s sharpest

such as spanners and knives.
