Although, in this case, not a cultural reference but the color of hinges. I needed double acting hinges for the privacy screen project, but they only come in brass plated steel, which is not a good look for this project.

So I tried using liver of sulphur to patina the brass. No luck. For some reason, the plating didn't tarnish like solid brass does. What I got instead, was a blotchy mess of various colors that looked like someone spilled something on them.

After a bit of pondering, I decided to try a gun blacking kit from Blue Wonder™. It's a four step process that removes the plating, bonds the colorant to the metal, and seals it. After a day of working with smelly chemicals, hot metal and some 3M abrasive wool, the results were better than I could have hoped for.

The deep, shiny black color nicely complements the ebony plugs. The project is nearly finished.

Cheers,
Tom

Nicely done, Tom.

Recently I watched a clock maker on one of those craft programs who turned me on to something I plan on trying; heating brass over an even flame to turn it a rich dark brown color. The material has to be surgically clean, no fingerprints, etc. He used an electric hot plate with a large thick piece of brass over the heating coils to evenly distribute the heat. It's supposed to be permanent and not tarnish. Hope to incorporate it into a turned piece one of these days.
