Why is this bronze bust so much more gold than the others?
It has to do with the way that the surface was treated. This golden color is actually the "true" color of bronze. The more common dark brown color is a result of potassium sulfide being applied to the surface which then reacts with the copper in the bronze.
Why is Suzon the only piece that looks the color of Bronze although that is not the newest piece?
Many of Rodin's works were treated after being cast with patina that would affect the finish of the bronze!
Interesting. Thank you!
You're welcome!
How come this Rodin statue has a blue/teal hue to it? All the other bronze statues have that familiar black/copper undertone. Is it a different material? Also, why is bronze black?
Each of Rodin's sculptures is treated with a combination of chemicals whose purpose is to change the surface color and finish, or patina, of the bronze cast. During his life, Rodin was very specific about the patina of his works with colors ranging from dark, almost black, to green, to even gold!
Dark brown patinas were achieved by applying potassium sulfides to the surface. Green is a natural result of oxidation of the copper in bronze but can also be achieved by adding chlorides to the surface.
You'll notice a sculpture that looks almost like gold in this show, which is much closer to the natural color of bronze. It is the bust of a woman called "Suzon."
Yeah Suzon looks like an Olympic medal. Every one else looks like they were hewn out of a mountainside. Thank you for your help!
