Saw something about it before, it's like a paint thinner or something to give old metal a black looking finish. No it's not paint for the smart azzess.

Not sure what your wanting to do, but the Vineagar will cause the surface rust to turn black, might even turn the metal black if left on long enough, but I'm not sure how uniform it would look.

Are you looking for a "finished" product? Maybe gun blue of some sort,

I've used vineagar to get rust OFF of parts and the result is it turns the part black, but I always wipe it off and oil it up or paint it depending on what the part was in the first place. I've never gone for the Pantina look, I just know that vineagar creates a reaction with rust and turns stuff black

Dunno If ya get it in the States, but "fertan" makes a Black Finish when it changes rust back into Metal... You can let it stay so, its like a Secure Layer on the Metal...

I made a vinegar/peroxide/saltwater mix that turned my bare metal parts rusty. It was the fresh bright orange rust. I oiled it a few times with wd just to keep it from immediately dusting my clothes and just left it for about a year now its kinda brownish. I might hit it with just vinegar and see what it does to the rust if itll make black ive got a vision! Hahahahaha

Perhaps you're talking about Parkerizing? http://www.m1-garand-rifle.com/parkerizing/

I restore old furniture and Industrial age stuff that has a lot of ornate cast iron on it.

After sandblasting I wash with soapy water then use Gun Blue you buy at any gun store. Walmart may have it. Works awesome and it gives that original black iron look with out screwing it up with paint.

Parkerizing or black oxide?

If it's steel, or really anything but aluminum, you could use Oxpho Blue Creme. We use it on firearm parts all the time.

Just google "Cold Bluing". Theres hours of info to read but it's super easy once you try it.

Google black magic patina. Used it on some metal furniture I built, turned out really cool

Another weird one is mustard, sounds odd but kinda works. Check blade forums for some info on patina steel. Should still come close to applicable.

I used gun blue. And for $5.99 you can't beat it.

metal is a pretty general term.aluminum,magnesium ,steel.iron.wont react to chemical warfare in the same way.there are commercially available products available.google ornamental iron work.they are a good source

My girlfriend is a jeweller and she's using Reicar oxidizer for silver, gold and copper. For iron/steel, she's using Gun Blue. You can also look for MIDAS products/oxidizer. They are used for creating oxidized surfaces and nice patina on different types of metal.
