Copper Bronze Patina: Strong Alternatives to Anodizing

Summary for copper bronze patina Discussion

Bronze and copper statues cannot be anodized, according to Mark Gunn CMF, who notes that anodizing is limited to aluminum and some of its variations. In response to John Neelankavil’s question about giving copper and bronze sheet sculptures an aesthetic finish, Goran Budija suggests using patina methods instead, mentioning rust patina kits, copper acetate, and spraying or brushing ammonium chloride onto clean, grease-free surfaces. He also notes that liver of sulfur can be used as a ground color with a potassium or sodium polysulfide solution. The practical direction of the thread is to look into patinas and finishing books rather than anodization for these metals. The discussion is focused on artistic surface treatment for metal sculptures, both large and small scale, and includes a pointer toward artists and finishing resources rather than a true anodizing process.
