Nitre bluing can add a real touch of class to small parts of a gun, like screws. Let's take a look at this interesting process.
Here we have nitre bluing salts—they won't turn your gun pink, they'll turn it blue.
To use them, I need to melt the salts into a liquid at 650 degrees and a Lee lead pot will provide the heat. My parts are highly polished to 800-grit.
Holding the part in iron wire, I drop it into the pot and after a few moments, I remove it to card off the salts that have crystallized on the surface. I then place it back in the pot, watching for it to change color.
In less than a minute, it's already turned to a straw color and we're almost there. Quenching it in water will cool the metal, leaving it a bright electric blue.
The process is the same for the extractor: dip, card, dip, and quench.
After bluing all my parts, I spray them with oil to prevent rusting. The end results are spectacular.
