▸ The reading
interpretive · artRhodium resists every single acid — even aqua regia struggles — and that stubbornness scrubs the air: three-way catalytic converters spend roughly thirty tonnes of it a year reducing NOx. The most incorruptible seat on the row, employed entirely in cleaning up combustion's arguments.

▸ The lenses
▸ Discovery
William Hyde Wollaston — separated from crude platinum residues alongside palladium · England · 1803
▸ Stellar origin
r-process + rare supernova nucleosynthesisBuilt by rapid neutron capture in the most extreme cosmic environments — neutron-star mergers and possibly magnetorotational supernovae.
▸ Reactivity
Resists corrosion by any single acid (even aqua regia struggles)More inert than platinum in many environments. Reflective enough that mirrors in optical instruments often get a thin rhodium plating.
▸ Applications
- Three-way catalytic converters (NOₓ reduction)
- Optical mirror coatings
- Jewelry plating (gives 'white gold' its sheen)
- Glass-fiber manufacturing crucibles
▸ Curiosity
Every modern catalytic converter contains a thin film of rhodium — Earth's NOx pollution control runs on roughly 30 tons of it per year.
