This clip from Raw to Ready: Bombardier focuses on how the 1791 discovery of an unusual black sand on the banks of a river lead to several experiments to isolate the valuable titanium. In 1910, Mathew Hunter used a football field to test a theory. It was a success and opened the door to the discovery of the kroll process decades later that produced a plentiful supply of the precious metal. This process is still used today in the production of titanium. The strong metal is used to create the blades of giant commercial plane engines.
