Flint and Steel: What Causes the Sparks?

 · Fe2 + O2 = Fe2O3 + heat. Or in simple English: Iron + Oxygen = Rust + Heat. Rusting (oxidizing) is the exact same thing as burning, but unlike a campfire usually you will hardly notice it. Because of the relatively size of a typical iron object, the heat it gives off as it rusts dissipates too quickly for the heat to accumulate and be of much use.

Wrought iron

Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily welded.
