▸ The reading
interpretive · artAluminium spent the 1850s rarer than gold — Napoleon III is said to have honoured his best guests with aluminium while lesser company made do with gold. Electrolysis collapsed that scarcity into drink cans and aircraft skins. It survives by self-defence, growing an oxide shield the moment air touches it: abundance that learned to protect itself.

▸ Discovery
Hans Christian Ørsted — first isolated metallic Al; Wöhler refined the process two years later · Denmark · 1825
▸ Stellar origin
Neon-burning + supernovaeProduced in the C/Ne-burning shells of massive stars and dispersed when those stars explode. Trace amounts come from radioactive decay of ²⁶Al, a supernova fingerprint.
▸ Reactivity
Self-passivating oxide layer protects from corrosionPure Al would burn instantly, but the moment it meets air it grows a transparent oxide skin that stops the reaction cold.
▸ Applications
- Cans, foil, and food packaging
- Aerospace structures (light + strong)
- Power transmission lines
- Window frames and architecture
▸ Curiosity
Once rarer than gold — Napoleon III served his honored guests on aluminum plates while everyone else got silver.
