The final step is called "patination", in which the patina, or coloring, is applied to the bronze. Patinas will occur naturally over a period of years, from the trace chemicals existing in the atmosphere, but more often a specific chemical is applied to the bronze usually while it is hot (200¡- 400¡ farenheit.) The desired outcome is based on experience with the different chemicals and how they are applied.
I often talk about the patina as if one sits down to play the piano. Each "performance" is a little bit different from the last. Certain passages stand out there are often pleasant "surprises". The patina is where you must guide the process but let the work lead you...
Before the sculpture cools completely a coat of paste wax is applied. This wax seals the patina from the elements. When the bronze cools the wax is then buffed with a soft cloth. This gives the piece a beautiful glow.
Finally the sculpture is mounted on a base of wood or stone and then it is ready for its final site installation.
