Patination is the process that bronze sculpture or metal work can change colors. This is the chemical process of adding a thin layer of chemicals, which oxidizes the surface of the bronze work. This process then causes a color change

One of the most influential processes on a sculpture, and creative, might possibly be the patina. Most people don’t know how I color a statue, or that it’s even possible!

Chemicals determine the color

The type of chemical used determines the color that the bronze sculpture becomes! Cuprite is a chemical that can penetrate the pores of the sculpture. It creates a beautifully rich red on the sculpture. For a black or brown coloring, Copper Sulfide is to thank!

Color can be naturally added to the bronze sculpture due to exposing the art to natural elements. Corrosion of the metal can cause natural patina that can show up from colors ranging from brown to blue green as oxidation occurs. Adding colors to bronze sculptures is so interesting!

When I patina my sculptures, I work with a skilled artist who understands the chemicals to use as well as the level of heat that is needed to penetrate the bronze.  “Our Lady of Guadalupe,”uses many different colors  to recreate the historic painting accurately.

This patina artist used a torch and added the oxidizers at a head of over 300-degree Fahrenheit.

I love adding patina to sculptures to create a more realistic and detailed artwork. The colors and hues on a bronze sculpture not only adds depth and dimension, but a level of realism that ensures the highest quality of artwork for my client. Our Lady of Guadalupe is a good example of adding color to a statue OUR LADY OF GUADALUPE –
