Patination ART on Aluminium


Q. I'm looking for (books) procedures to patina (patination) aluminium. Basically for outdoor resistance 100% of the time (UV and waterproof) for sculptures. The patina on the aluminium must keep its finish but it could be reasonable to apply a coat of wax or clear Teflon or whatever 1 time per year. I find a book for patinas on bronze, copper or stainless but nothing about aluminium.

Artists Anodizing Aluminum: The Sulfuric Acid Process
from Abe Books



A. Hi Andre. Aluminum can be anodized, dyed, and sealed. It should exhibit extraordinary outdoor resistance as entire skyscrapers are built with anodized aluminum.

But whether this offers you the option for the art you envision is a question I can't answer.

Good luck.

A. You can colour aluminum directly, without anodizing!

Black for aluminum:
10 gm potassium permanganate
25 gm copper nitrate
4 cc nitric acid
1 lit water

Hot immersion / 80-100 °C)
5 min. = brown
15 min. = dark brown
30 min. = black

Q. Could anybody tell me if there is a coating one can apply to stop brushed aluminium anodising outside and keep up it's sheen.

A. Hi Claire. Aluminum can be clearcoated; lots of people polish their aluminum car wheels then clearcoat them. Also, the right alloys of aluminum can be anodized without losing substantial shine -- most dentists' lights and outdoor lighting reflectors, and many telescope mirrors are anodized aluminum.
