From the notes of Ruth Zuckerman:
Here, an artisan is firing my apples. The application of the patina is done with a blowtorch, acids, and water. Maroon patina was used for the bite marks, which appear darker in color. Later I changed the marble base to a lighter marble for more contrast. Here, a section of the bronze has been heated with the torch, and the first coat of patina has been applied. The process of heating, applying color, and sluicing off the acids will be repeated until the desired patina is achieved.
Different chemicals and minerals create different colors. The method of application is the same. After the color is achieved, it will receive a coat of wax to seal the color and protect it.
This was another version, which was very highly buffed and polished. Patina is applied only to the bite marks. It was filed, sanded, polished, and buffed, a most labor-intensive process.
