Topic tags/keywords: brass hardware brass patina brass

I was wondering if anyone has any experience using JAX chemicals to create a dark patina on brass hardware. I am making some small drawer pulls and wanted to create a dark patina to accent some ebony inlay on the piece instead of the shiny brass. I know that there are a lot of formulas for patinas out there, but I choose JAX because it is quick and offered an option for brown-black and black.

Has anyone used this? I cleaned the part with mineral spirits and submerged it in the solution, per instructions. And within a few seconds the piece changed color and was within the color range I was looking for. The problem is as soon as I took it out, the oxidation rubbed off immediately, just by handling it with a cloth (no rubbing). Being that this was my first time using this, I thought maybe I didn’t leave it in long enough, so I tried several times but all had the same results, more or less. The oxidation came right off, in big flakes in some cases, immediately.

Any advice?

to make any patina “permanent” on softer metals such as brass, silver, copper, gold etc… you have to brush it with either a steel or brass bristle brush. the steel gives a “whiter” shine and the brass a “yellowish” one. if you don’t it will simply rub or wash off. to prep the surface clean it with a clear, unscented ammonia, rinse with water, dry it off and apply your patina solution, then BRASS BRUSH IT. you can even use a flex-shaft or drill attachment to do this, i recommend it simply because it is much faster but WEAR EYE AND FACE PROTECTION because they do throw the tiny wire bits from the brush EVERYWHERE!
another note: pour a small amount of your patina solution into a separate cup for use and discard what you do not use, if you pour the used solution back into the bottle or put your application brush directly into the bottle you WILL contaminate the bottle and weaken your solution.
