Finishing Process

The last step is the finishing process. The entire sculpture is blasted with sand to prepare the surface to receive a patina, which establishes the final color as well as provides a protective layer. The color, of thousands available, is achieved by applying specially formulated chemicals, similar to ceramic glazes, in one to six layers, depending on the color desired, onto the raw bronze. Portions of the sculpture are heated, and then a chemical is applied, by brush or sprayed on, each giving a different texture. This process of adding heat and applying chemicals is done over the entire sculpture for each layer. Once all the coats of the finish are applied, a final coat of a clear sealant is applied to protect the finish. Weeks says, “All bronzes will darken over a long period of time.”
