A long time ago I read that Texas A&M used cow manure to age a new brick building so it would fit in with the others.  The technique was called "animal patina" IIRC.

In ye olden times (and in 3rd world countries) tanning a hide to make leather used dung, urine, cow brains etc. and it sounds a bit like the process you have just followed. So perhaps modern tanning techniques would age the brass as well. I found this crowd (with an outlet in Hunstville).

Just a thought.

Max, would be interesting to experiment with llama dung on brass.  Google "Llama dung leather" to see other uses :>}

I like the scientific way you went about ths!

I think it may have been me who mentioned the Imagineers' method of aging brass.  I have scoured the Internet, but I have not been able to find any references to the recipe. My vague recollection is that in addition to cow poo it included straw, vinegar, and molasses.  I could be wrong abnout the other ingredients- it's been many years since I got the tour of the "underside" of Epcot Center.

This sounds like a problem the steampunk community and its suppliers must have faced regularly. It might be worth researching their results.

 

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 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.

The best way to age it could be just leaving it in your open backyard space for a couple of months - the atmospheric dust, sunlight , rain and the pollution of the vehicles will do the necessary.

 

How about attaching those brass plates on your car so as to face the car exhaust?

Thanks for mentioning that.  I had noticed the same thing, but I thought it was just me.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
