It's a beautiful Patina! I tend to use more creative Patinas than that, particularly amonia and salt for a good blue, or my favorite... a combination of Feric Nitrate applied hot, and Copper Nitrate (Miracle Grow). The combination can create a layering effect of blues, greens, reds, and blacks. Here's a link to my most favorite piece I used these patinas on. It's a copper Martini glass I made out of scraps. : ) http://www.facebook.com/photo.php?pid=30256102&l=2b9e556968&id=1457880199 Heck it is friday : ) On a more serious note though....your pipes aren't at least a little blue or brown where they attach to the propane tank and are exposed to the elements? I have some great patinas there and would assume everyone does. Copper reacts to the atmosphere and patinas, it's just what it does. Throw some salt into the equation..... and it does some crazy things. I would not however, worry in the least bit about the depth of the patina. It's simply a surface corrosion, far less aggressive than rust. -Craig '85GL turned WESTY BOSTIG in the back 4000 miles on the conversion and still going strong (in less than a month) On Fri, Jun 19, 2009 at 6:32 PM, neil N<musomuso@gmail.com> wrote: > On Fri, Jun 19, 2009 at 6:20 PM, Jim Felder<jim.felder@gmail.com> wrote: >> Leave it to a brass musician to want laquered shining propane tubes. >> Maybe a little mother of pearl? >> >> Jim >> > > Ha! > > Yah, and you'd think someone with brass *repair* experience would be > able to assess things. <rolls eyes> But trombones et al don't contain > flammable gases, (not often anyway ;) and they don't operate under any > amount of real pressure.
