oxidised
Reacted with oxygen
Oxidised is the British spelling of oxidized.
When something is oxidised, it has undergone a chemical reaction with oxygen—iron oxidises into rust, copper oxidises into green patina.
The term extends to any reaction where a substance loses electrons: The wine had oxidised and turned to vinegar.
Oxidised finishes on jewelry or metal are deliberately darkened for aesthetic effect.
