How do artists simulate the appearance of age or weathering on aluminum figurative sculptures?

Artists use various techniques to simulate age and weathering on aluminum figurative sculptures, creating a sense of history and texture. One common method is applying chemical patinas, which react with the metal to produce oxidized, rust-like, or verdigris effects. Acid washes and saltwater treatments can accelerate natural corrosion for an aged appearance. Texturing tools like wire brushes, sandblasting, or chiseling add physical wear to mimic erosion. Some artists layer paints or waxes to enhance depth and simulate dirt accumulation. For a more controlled approach, airbrushing or dry brushing with pigments creates subtle weathering. These methods allow sculptors to achieve everything from gentle aging to dramatic decay, adding character and storytelling to their aluminum artworks.
