How To: Rust Bluing.

[AFJuvat]

After applying the rust blue solution three times, I dropped the parts into the pot of boiling water and let them boil for about 10 minutes.

The heat and the boiling water converts the red rust (Fe2O3) to Magnetite (Fe3O4) Magnetite has a blue/black color and is much more resistant to corrosion.

Pic 14 - Parts removed from the boiling water. They have turned black, with some red rust still on the surface. With repeated application, the amount of red rust remaining becomes less and less.



Pic 15 - Same parts, after carding off the "fuzzy" stuff on the parts as seen in picture above. No red rust on the parts, which have turned a nice blue/black color.



I repeated the process above three more times, though each application/boil cycle was progressively shorter and shorter, as there was less free iron left to oxidize. After the 4th application, I carded the parts and then turned up the heat in the toaster over to 250 degrees to evaporate any water left on the parts.

After 24 hours, wiped off the excess grease. The bolt came out really well. too bad it is a junker part.
