▸ The reading
interpretive · artEvery flick of a lighter is cerium burning — the flint is a cerium-iron alloy shedding pyrophoric sparks. It is the most abundant of the rare earths, which are famously not rare, and it stores oxygen inside catalytic converters. The most casual daily fire on Earth belongs to this seat.

Jöns Jacob Berzelius + Wilhelm Hisinger (SE) and Martin Heinrich Klaproth (DE) — simultaneous, independent · Sweden / Germany · 1803
▸ Stellar origin
s-process in AGB starsMost abundant lanthanide. Slow neutron capture builds cerium in dying low-mass stars; planetary nebulae carry it out.
▸ Reactivity
Pyrophoric — sparks when struckCerium-iron alloy (mischmetal) is what makes a lighter flint spark. The cerium is the fire.
▸ Applications
- Lighter flints (cerium-iron alloy)
- Catalytic converters (oxygen storage)
- Self-cleaning oven coatings
- Glass and ceramic polishing powders
▸ Curiosity
Sparks struck by a cigarette lighter are cerium burning — every flick is a tiny pyrotechnic display of the most-abundant rare earth.
