    Pyrite enjoyed brief popularity in the 16th and 17th centuries as a source of ignition in early firearms, most notably the wheellock, where a sample of pyrite was placed against a circular file to strike the sparks needed to fire the gun. Pyrite was used with flintstone and a form of tinder made of stringybark by the Kaurna people, an Aboriginal Australian people of South Australia, as a traditional method of starting fires.
