@antedeluvian: In ye olden times (and in 3rd world countries) tanning a hide to make leather used dung, urine, cow brains etc....
In Roman times they used the ammonia from unrine to wash clothes -- I heard about the cow brains for tanning -- I don't know if I have the stomach to try that on my brass. I'll check out that website you mention (how do you find this stuff?)
P.S. Is it unreasonable to expect that clicking on "Post a comment" at the top of the article, or "COMMENT" at the bottom might bring up this panel?
Neither seems to have any effect; the only way to enter a comment is by clickling on "Reply" in someone else's post.
I don't seem to have this problem although I have had similar problems in the past, and it was tied to the browser I was using. I maintain Internet Explorer, Firefox and Chrome on my desktop for just that reason. Currently IE seems to work fine.
I can understand the smells you are talkign about. I do composting of kitchen waste at home so can figure out. Yes cow dung is extremely rich in so many minerals. Dried cowdung is used as fuel in many parts of India. Comingto the aging of brass, the pictures you have put looks like a piece of art. Where are you going to use them...I mean why would you age the brass.
