"Turning Copper Green Fast"





February 2, 2010

About 8 years ago I commissioned a beautiful hammered pure copper bass relief wall sculpture of a blue heron in flight, made from annealed pure copper sheet. The piece is about six feet tall. To date the metal has turned to a brownish patina. As we live in Florida it is very humid most of the time. I thought that by now the copper should have turned green. I have been told that it may take 60 to 70 more years for this to happen. As I am turning 69 this year, I do not have that much time to wait. Are there any commonly available household products that will speed up the tarnishing process? ie: ammonium cleaners. I do not want to use paints, etc. that will cover the natural copper.
Thank you for any help you can give me.

Hi, Fabian. Send a picture if you get a chance. The fastest and easiest way to a green patina is with a green patina solution like Jax Patina [affil. link to info/product on Amazon]. This is not a paint, it is copper salts similar to a natural patina. If you want to use stuff of a more homemade nature, please search the site for "green copper". Good luck.
