Rust Bloom — Iron Oxidation Propagation Study

Mild steel plate in the early stages of atmospheric corrosion — the rust bloom propagating outward from an initial scratch through the protective coating, the iron oxide growth front showing vivid orange and brown oxidation chemistry.
Description
Iron oxidation photography documents one of the most ubiquitous chemical processes on earth — the conversion of metallic iron to iron oxide at the metal surface. This image captures the specific photographic opportunity of early-stage rust bloom: a mild steel plate with a damaged protective coating, three weeks into atmospheric exposure, shows the oxidation propagating outward from a scratch-initiated site. The rust front advances as a clearly defined boundary between the grey metallic surface and the orange-brown iron oxide zone. Within the rust zone, the chemistry’s progression is visible in the colour gradient: vivid orange hematite at the active leading edge, darker red-brown goethite in the intermediate zone, and near-black magnetite at the oldest central region. Shot at 2:1 macro with raking sidelight at 8 degrees, the three-dimensional texture of the rust surface — its granular topography of crystal growth — is fully resolved.
