Helix Gunsmithing offers Blue Nitrate.  The nitre bluing process (sometimes referred to as fire bluing, peacock bluing or niter bluing) is a gun metal finishing process involving a salt bath solution of sodium and potassium nitrates, heated to exact temperatures.

With proper care and handling, this process need not ever be repeated, making this a valuable investment to a weapons owner.
