Patina (noun)
A colored film on the surface of a metal sculpture. Sometimes the patina appears over time as a result of the oxidation process and other times artists create the color with a wash of chemicals.
Rodin developed his own techniques for creating a patina using light and dark greens on his bronze sculptures to give them a marbled effect. The patina is an important element of Rodin’s sculpture because it accentuates the lively surface, as it does on his Thinker, which, in turn, emphasizes the psychological unrest Rodin found in the modern world.
