   It does work but it takes time unless you are using a strong grade of ammonia. You will find other quicker ways of patination on a more related site such as http://completesculptor.com/

   I have done a lot of patina work as I was a sculpture major in college. That source will get you all the info and patina solutions you will ever need.

   I have gotten good results from nitric-acid which I got from a stain-glass supply.
   It turns lead black, and may have been called black patina something.

   The August 2001 Wood Magazine (Sorry about that FWW) had a jewelry box project in it that called for an oxidized copper top. I have made several of them with good success. If you don't have access to that issue, email me and I will send it to you.

   Regards,

   You might want to ask at Breaktime. The question comes up fairly frequently there regarding copper roofs and lighting fixtures. Or do a search of there for "green copper" (without the quotes), or verdigris.

   In re-reading my response to your question, I realized that it appeared that I was suggesting that you build a jewelry box. I should have pointed out that there are detailed instructions in that issue of Wood Magazine for etching copper with ammonia.

   Regards,

   Try a company called modern options.  They copper blue and copper green, to name a few

   http://www.modernoptions.com

   They sel their products at some Michaels Art stores, and I have seen/bought it at home depot.  They even have a paint the has copper particulate in it.  The "acid" finish works on the paint product, solid copper, and even copper plate, but it will cause rust on areas that weren't copper plated sufficientlt.  This was my experience on a pot rack that I had plated.

   David Marks of the Woodworks program on DIY TV has had several episodes where he has done copper patinas.  I assume you could to to his web site http://www.djmarks.com and get some information.Alan & Lynette Mikkelsen, Mountain View Farm, est. 1934,  Gardens & Fine Woodworking, St. Ignatius, MT
