Bronzed Shield Boss

I'm really happy with the way this shield boss turned out: I'm not even going to bother etching or engraving it.

The boss was baked at 475F for about 30 minutes, then quenched it in water, dried it, and treated it with a fine mist (spray bottle) of vinegar & salt solution to corrode some of the finish. After 30 minutes of corrosion, I washed the shield boss with soap and water, wiped it down with alcohol, baked at 520F for 40 minutes, then quenched with water and oil I poured about 2 cups of vegetable oil into about 2 gallons of water, and the oil formed on the surface).

The result was a very interesting patina. There is a very fine dark lacing / marbling on the surface, though it's hard to tell from this photo.
