▸ The reading
interpretive · artTantalum refuses every acid but hydrofluoric and refuses to irritate living tissue — so it holds both the capacitor in nearly every phone and the surgical plate in a healing skull. Much of it is strip-mined as coltan in Central Africa, with all the geopolitics that implies. Inertness, it turns out, has a supply chain.
The science below is cited as science; the symbolic layers are flagged as interactive art.

Anders Gustaf Ekeberg — separated tantalum oxide from columbite · Sweden · 1802
▸ Stellar origin
s-process + r-processTwo stable isotopes ¹⁸⁰mTa and ¹⁸¹Ta, the metastable ¹⁸⁰mTa being the rarest naturally occurring nuclide on Earth.
▸ Reactivity
Resists even aqua regia — but hydrofluoric acid dissolves itNamed for Tantalus — the mythological figure who could never quench his thirst, mirroring this metal's refusal to dissolve in acids.
▸ Applications
- Capacitors in nearly all modern electronics
- Surgical implants (biologically inert)
- High-temperature furnace components
- Specialty steel alloying
▸ Curiosity
Smartphone power rails still lean on tantalum capacitors — most of it strip-mined in Central Africa from coltan ore, with all the geopolitics that implies.
