corrosion zones

festival pavilion

The marine environment, with its omnipresent salt and moisture, is powerfully corrosive. But rather than being an all-or-nothing phenomenon, corrosion depends on context, with local microenvironments producing a range of effects. These chain links rust very differently depending on how deeply they are suspended in the Bay. Copper patinas vary from brown to orange and red to green; in the most corrosive zones, the heavy links actually swell and crack apart.
