A piece of flint 9–10 cm (3.5–3.9 in) long, weighing 171 grams. Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, [1] [2] categorized as the variety of chert that occurs in chalk or marly limestone. Historically, flint was widely used to make stone tools and start fires.
Ferrocerium is used in fire lighting in conjunction with a striker, similarly to natural flint-and-steel, though ferrocerium takes on the opposite role to the traditional system; instead of a natural flint rock striking tiny iron particles from a firesteel, a striker (which may be in the form of hardened steel wheel) strikes particles of ...
The steel must be hardened but softer than the flint-like material striking off the spark. [12] Old files, leaf and coil springs, and rusty gardening tools are often repurposed as strikers. Besides flint, other hard, non-porous rocks that can take a sharp edge can be used, such as chert, quartz, agate, jasper or chalcedony. [2]
A spinning steel wheel provided a good stream of sparks when it engaged the flint, and a tinderbox designed to do this was known as a mill. [10] In a modern lighter or firesteel, iron is mixed with cerium and other rare earths to form the alloy ferrocerium. This readily produces sparks when scraped and burns hotter than steel would.

The steel should be high carbon, non-alloyed, and hardened. Similarly, two pieces of iron pyrite or marcasite when struck together can create sparks. The use of flint in particular became the most common method of producing flames in pre-industrial societies (see also fire striker).
