Rust blued interiors?

[Kyrie]

Hi BCC,


The cold rust blue process and the hot salt blue process are fundamentally different processes. In the rust blue process the bluing solution is only applied to (brushed on) the surfaces to be blued - hence the inside of the frame is not blued. In the salt blue process the entire pistol is immersed in the bluing solution - and so the inside of the frame is blued.


If, in the rust blue process, the inside of the frame was painted with the bluing solution it would be nigh on impossible to get the blue off of the inside of the frame without damaging the blue on the outside if the frame. Whether the inside of the frame is polished or not really doesnâ??t have anything to do with the bluing method, as bluing is removed by chemical means rather than buffing.


Hope this helps!


Best regards,


Kyrie
