Ways to blacken stainless steel without seleniumApril 24, 2012
Q. I am working on a series of environmentally friendly ways to patina various metals.
My question is this: Is there any way to blacken stainless steel that doesn't involve selenium. I have heard that phosphoric acid can have this effect, but have not had any luck so far.
I am looking for a method that could be applied to large pieces of furniture, so immersion wouldn't be my first choice.

A. Old and good oil blackening is simplest way to blacken SS. Oil it very, very lightly and then heat it to max 400 C (slowly, you can use hot air gun). Any edible oil can be used but linseed is the best. Hope it helps and good luck!Goran Budija
