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.

We could also call it a "bovine buff"

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.

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?)

Thank you -- I've spent so much time and effort on the rest of the Inamorata Engine project that I think it's worth while making the brass panels look as good as possible.

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.

I thought I would take you up on your challenge. I didn't find one but I did find this which may be for a Blackmax cow, depending on how you parse the product title. What I did find puzzling is quite what this device is supposed to do. Read the description.

What is hardware disease? Does my computer have it? Do cows suffer from software disease? Does the cow swallow this magnet? As Arthur Fallowfield (Kenneth Williams) on "Beyond our Ken" used to say "The answer lies in the soil!"

My understanding is that cows can pick up bits of metal when they are chowing down on the grass in a field -- you sick one of these down their throat and it attracts any magnetic metals and holds them tight as the thing wends it's way through the cow's stomachs

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

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.

These are just small test pieces. Take a look at my most recent Inamorata Prognostication Engine column -- that shows the full-size brass panels I'm using in a 1929 wooden radio cabinet. I want these panels to look like they are 100 years old -- not brand new and shiny...

Now, of course, you have the perfect test bed for testing brass cleaners. I wonder if taking a piece that had been, um, over-aged and then cleaning it abit might give you a piece that looks more authentic, since the corrosion has gone deeper.

That is a VERY interesting idea -- I will try that on one side of my test pieces (I'll keep the other side "as is" because I do like the look, even though it's too much for the main panels.

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.

 

What browser are you using?

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?

My friend, you always manage to surprise me. This is one of your weirdest (known) experiments ;-)

My 5 cents about the different results you have obtained with the cow poop and the horse doo-doo: the horse's one is very appreciated as a fertilizer, far better than the cow one... but "cow poop" is widely used because is cheaper to obtain -- believe me, I've been buried up to my knees in that "substance" while helping my father at his bulls farm!!

This makes me suppose that the horse "doo-doo" wins in your aging brass experiment because contains a higher amount of ammonium and other chemical substances.

I think you are right -- and since you have such ready access to the stuff, if I decide to go that route I will send you my brass panels along with detailed instructions on how I wish you to age them LOL

As i recall, you live in Pamplona. And your father raises bulls. Is it too much of a leap to ask if your father raises the bulls for Pamplona's famous event?

I think the 'tasty' you are looking for might be better achieved by etching a border design before applying a patina. There's some how to out there if you google it.


There's this darkmagnet site that seems to be doing similar stuff to what you doing. You're not allowing links so google "darkmagnet wordpress".

Steam Punk Patina
ccalvin   8/29/2014 10:55:41 PM

I sent the cow/horse poop suggestion to my son (potential steam punker) and wife (former (perhaps perpetually) farm girl).  My wife provided this response:

Fast-tracking patina for
brass:  (from Mom)

Left on its own without any intervention, unlacquered brass will begin to
darken in about a month and will continue to take on a deeper patina with age
and use.  (Look up the next time you are seated at our dining room
table.)  To accelerate this process, placing the items in HOT water will
speed up the oxidation.  Another trick is to place an open can of
traditional latex paint next to the unlacquered brass item in an enclosed area
for at least 24 hours.  The fumes from the paint will quicken the patination
process.


And, by the way, BRASS IS BACK, in a big way.  The appetite for nickel and
chrome is at the saturation point.  Just ask Martha Stewart.
