How to 'age' brass' ?
I am restoring a Burndept Ethophone which has a fancy brass escutchion.
My one was covered in enamel paint and now I have removed the paint, I have a shiny brass escutchion. I want to return it to something like the original finish. which was an antiqued patina. Any ideas what to use? To see an example of what it should look like, have a look at the photo in the parts wanted section under Burndept Ethophone. Thanks |

Hi Peter,
I've had some very good results in the past with a product called 'Tourmaline'. It's made by Liberon. Try here - http://www.axminster.co.uk/product.a...39VPWS3B5QZCR6 HTH Colin Last edited by Colin; 4th Dec 2005 at 6:24 pm. |

Re: How to 'age' brass' ?
The traditional method is "liver of sulfur" (impure potassium sulfide). Dissolve a pea-sized chunk of the stuff in hot water, which releases hydrogen sulfide, and immerse the brass for a few seconds or longer, depending on the concentration and the desired darkness.
Here in the States, a company called Birchwood Casey in (I think) Minnesota sells "Brass Black" which achieves the same result by plating out a thin layer of arsenic on the surface. The elixir previously mentioned may do the same. |
