Bronze and Copper statues - Anodization method (for aesthetic/artistic appeal)

Q. I am an artist & entrepreneur sculpting and marketing relief statues made of copper & bronze sheets. I would like to get information on the method of "anodization" of the metallic artifacts to give them aesthetic appeal, both in large scale & in small scale (semi manually/manually). I will be eager to be in touch with artists/sculptors working on metal sheets and business firms dealing with such artifacts.

A. Green patina for copper:

1 lit. vinegar [in bulk on eBay or Amazon]
20 gm copper acetate [affil links]
20 gm ammonium chloride

MAY BE SPRAYED OR BRUSHED ON OBJECTS (grease and oxide free)! If you want you may use liver of sulfur [on eBay or Amazon] patina as ground colour(10-50 gm potassium or sodium polysulfide, 1 lit water)!

A. John,

Bronze, Brass and copper cannot be anodized. Only aluminum and some of its variations can be anodized. Suggest you get one of the good finishing books advertised at this site and check out patinas and finishes .
