blackening stainless steel

[kokopelli]

anyone (crank) ever try/use any of the *few* stainless steel blackening techniques?
-BESIDES a 'spray paint' type coating like Dura/Cera/KG/kote

I know of one smith who does some kind of voodoo salt bath that allows him to 'blue' stainless, and another place that does some other witch doctor concoction that supposedly 'changes the molecular structure' within the metal allowing it to be darkened...

done some google-foo'ing and saw those, wondered if anyone has experience with anything?
-got a stainless slide and I want to go to the dark side...

Hahaha voodoo =droppings from a bull with clap.

Oxyate 84 will blue but good luck
It is crap shoot with me
Quite trying years ago

Send it off to get black chromed
Easiest is black Cerokote

Stainless steel will rust and that will color it finally after 100 years

Bluing is rust so you are trying to rust something design to resist that

Oxy84 you dick around between 200/300 degrees
Dunking the gun in ice water and back in the tank and all types of technique.

Here's Claude using the Oxy84:

S&W uses melonite on their M&P series pistols which are stainless. I dont know of anyone local who does this.

This is on another forum

Evidently some form of cold bluing.
But any cold blue that I know of is a form of chemically false plating and only works on ferrious steel.

I used Sulfamic Acid from home depot to patina my stainless blade. About a half hour to produce this effect. Longer turns it darker.

Not black-grayish and requires laquer to seal.
Like I have said before
Paint baby

That cool but I bet it is not very durable.
It to would require a sealer coat.

I bought another blank that I'm going to test on. This one I'm going to leave for an hour then check, and try to get a deeper etch with the acid. Also trying to mix less of a paste and more of a slurry to see what it does. At most I'm ruining a $10 knife blank.
