After I worked on the touch up chasing of the sculpture, I turned it over to Clay and he sandblasted it for the last time. This removed all of the minute bits of metal left by the burr on the grinding tool. The metal is a pinky gold color when it first gets sandblasted. After the humidity hits the piece it changes it to a more golden hue. I love the metal when it’s gold. The bronze reflects light but at the same time the reflection turns in on itself and makes the piece glow with an inner energy.
Applying chemicals to the sculpture turns it to what we’re trying to copy; ancient Chinese bronzes which have been buried for a thousand years. You can chose from a vast array of colors for a bronze sculpture. I opt for a classic color, the French Patina. Sometimes I apply bismuth (same chemical that you use for an upset stomach) which is white but in the final result is slightly antique looking.. It has become my signature patina. I don’t like dense patinas that obscure the reflective quality of a waxed bronze.
The Barbaro sculpture has several solid pieces which need to be evenly warmed up to accept the patina chemical. It’s slipped into a large warming box.. After it’s warmed the piece is sprayed with the black (known as liver) color.
