Gregor discovered titanium buried in black river sand

HERE’S THE INTERESTING PART

William Gregor was poking around a stream when he noticed a magnetic black sand that didn't behave like standard iron ore. He subjected it to harsh acidic treatments and isolated a deeply unyielding white powder. He unwittingly uncovered titanium, a metal that would eventually become the gold standard for virtually unbreakable engineering.
