Artists have long embraced the natural oxidation process as an integral part of metal sculpture creation, transforming what many consider deterioration into breathtaking artistic expression. By carefully controlling environmental exposure and chemical reactions, sculptors guide the formation of rust and patina to achieve specific visual effects.

The oxidation process begins when metals like iron, copper, or bronze react with oxygen and moisture. Sculptors often use weathering steel (Corten steel) for its predictable rust patterns that create a protective layer stopping further corrosion. For copper alloys, artists induce patina formation through controlled applications of chemicals like ammonium sulfide or vinegar solutions, producing vibrant greens, blues, and other colors.

Some artists accelerate oxidation through techniques like saltwater spraying or burying metal pieces, while others allow nature to take its course over years. The resulting textures and colors become permanent features of the artwork, telling a story of transformation. Contemporary sculptors frequently combine oxidized and polished metal sections to create striking contrasts between weathered and pristine surfaces.

This intentional use of oxidation challenges traditional notions of metal preservation in art, celebrating impermanence and the beauty of natural processes. The ever-changing surface patterns make each oxidized sculpture unique, with its appearance continuing to evolve subtly even after completion.
