Brent, don't know. never tried that high a temperature.
With my nitre fertilizer pot, get a nice dark blue on screws and springs at about 700F.
Lower the temperature to about 600F to get the pidgon egg blue some people like.

Yes, to get the blues, lower temps. I have done that many times in lead and in nitre, but I wasn't looking for blues like that. I was looking for that charcoal color that Fred got. I did not quite get there. As far as I'm concerned, I won't get there with lead. Maybe nitre, but I suspect, it will have to be the right way - with charcoal. No shortcuts.

You get a nice black in niter salts at about 825 degrees, I think 880 is too hot.

....The pot got to just under 900F. About 880F or a titch higher. That's as high as I was willing to go....
....At the 20 minute mark....
....I would not want a whole action to deal with like this.... If the goal is to put a final finish on an entire action, a decision should be made ahead of time on the preference to retain any hardness that was present and considered desirable.

Steve, I'll back down and give that a try.
It is worth noting that a highly polished mould sprue plate turns pretty nicely black and it certainly never gets to even 800F, but it takes a long time.
