How to form patina on brass?

Bury it in wet earth for a day or two

AWEM

I did some repair work on an casting that was part of an antique easel for an art dealer. I matched the patina with an airbrush with layers of woodworking stains finished with a clear coat. The dealer said that the job was perfect.

I use a chemical sold as "Liver of Sulphur" by some jewelry supply and crafts shops.

Works great for me.

Pack it in sawdust in a waterproof container. Piss on it for a couple of weeks. Really.

Check in Machinery's Handbook-----where it details how to color brass and bronze.

[Try sealing it up in a plastic bag with some open containers of household ammonia.]

After cleaning a brass black powder revolver, take a wet dirty patch (such as one that just cleaned the bore) and wipe the brass and let it set. The black powder residue really makes a gun look very old in a short time.

I'm really surprised nobody has told him to pee on it yet.

Piss on it.

may help you out. We were looking to possibly age a small reproduction of a South Bend Lathe dauber we make, (we decided to sell it as a fresh turning instead so not to imply it was the original item). Tim "A-LEE-SAM"
