Blue-Black Cold Blue?

rhmc24
Wondering if there is a 'cold blue' that gives a closer to black than most. I have several, best I think is Brownell Oxpho Blue but I'm looking for something nearer to black. Any thoughts, comments, experiences appreciated. Thanks

    I use Brownells Dicropan T-4. It states on the label that it "Blends with all Blacks". It works well.

    I have T-4. It is good but I want something darker. Maybe something that will build up, get more dense with more applications. I have Belgian blue that only needs hot water. I have used it OK but never kept applying it to see how dark it could get. Another experiment?

    Well, problem is, color is obtained by chemically changing the outer layer of steel- unlike paint which is added to a surface. When the chemical changes that layer- THAT'S what yer gonna get.

    Some cold blues are better than others, and some work better on this steel than that steel (alloy difference)

    But I don't think you will find a cold blue that equals hot caustic bluing.

    11b6r - You are right. What I need is something that will approach the blue-black of early Colt automatics, bone charcoal blue of a mirror finish. Specifically I have assembled from parts a 1902 .38ACP with a slide about 60% on to a new never used in-the-white frame I want to finish to match the slide. I know I will have to distress the result a bit to harmonize with the slide.

    I have lately focused on pre-1911 types. Several resurrected from parts-gun level. If I resolve the current question it will have several other applications. This is a DIY thing for me. If I wanted spend the money and bypass the challenge I could just buy a hi-condition piece for $4K.

    Thanks and any further info appreciated.
