How do you blacken steel with heat?
You only have to heat the steel up to around 500’/600’F and then spray, dip or brush(with a natural bristle brush, not plastic). You can repeat as needed to get the shade you need. Also the various food type oils will give slightly different colors and shades from brown to black.
Does cold bluing prevent rust?

Why is my stainless steel turning black?
Stainless steel turning black is an oxidation process called rouging, and can be caused by many factors: exposure to oxidizers, contact with non stainless steel metals, or exposure to high heat.

Can you black oxide aluminum?
The process is called Lumiclad® electroless black oxide for aluminum alloys. Machined frames and cages that support electronic components have a protective coating thickness of just 0.000060 inches (1.5 micron) using the new Lumiclad process. The finish is smooth, durable, and electrically conductive.
