(Heat) Oxide colouring is great for delicate parts but doesn't offer the increased wear resistance and oil retention of gun blues making it less suitable for larger, regularly used and handled parts.

Nick

Can one obtain an electric blue or fairly light blue with Gun blue?
Most Gun Blue that I have used over the years gives more of a black blue.
also the blue that I am looking for must be very even, not mottled at all.
any comments would be appreciated.

I cant speak for lighter shading aspect but the Clickspring series shows his method & some nice results in terms of evenness & lustre.

My point is simply that (Heat) Oxide colouring is great for delicate parts like clock screws which are not often handled but it doesn't offer the increased wear resistance and oil retention of gun blues making it less suitable for larger, regularly used and handled parts, if you used it on a trigger for instance it would begin to wear off with relatively little use.

Unless you recommend (Heat) Oxide blues for firearms and items subject to wear?
Any comments would be appreciated ;-)

Nick.

I am asking from the clock makers point of view. If gun blue gives oil retention and harder wear and I can obtain the color I am looking for, then I want to use it on clocks. Clock oxide blue would not work on guns as you say. Thjanks.

Nitre Blue for guns gives a similar iridescent bright blue as the heating. It is only for show pieces normally, as it doesn't hold up to a lot of handling as well as a normal hot blue.

I like to rinse well with hot water, oil and let sit for a day, then wipe off oil and wax with car or furniture wax.

What oil do you use. I can get a good blue but when I oil it, the blue goes dull. I use engine oil.Thanks for the feedback.

I usually use a vegetable based cooking oil for that. Olive, sunflower, canola, etc. The motor oil may have chemicals that attack the blue. Or skip the oil & go to wax.
