I didn't realize (but should have known) that you already had a piece weathering naturally for comparison. I'm interested to see this process and I'll bet that book mentioned earlier will be a big help.
I'd love to see them in person, but I actually might be making my way to Huntsville, AL before the next ESC. Which might save you from having to explain how you aged the brass to the TSA. :)
Also I'm not certain I'll be able to make it to ESC again this year but I'm hopeful!
@Clarke: I'd love to see a couple of brass pieces for comparison.
I'm trying different techniques and keeping all of the results -- I have a piece on the roof of my office building as we speak -- it's been up there for a week now in the sun & rain with a dash of polution -- I need to go up there ant photograph it -- I plan on doing that week by week so we can see how it evolves -- bujt it's drizzling at the moment and the ladder on the side of the building is dangerous enough as it is .. so I'll wait a bit :-)
If you are really interested, I could bring out all of my test pieces to ESC Silicon Valley next year...
Next time I think we could really use a picture of you working with the cans of poo. You know, just to set the scene. ;)
I have absolutely no experience with aging metals but I'd love to see a couple of brass pieces for comparison. I'm thinking an untarnished brass piece and a naturally aged brass piece (weathered outside) alongside the new brass pieces as you try new methods.
As always, looking forward to seeing the next step!
