Carbonia Bluing

Carbonia bluing is one of the most varied finishes by manufacturers. They all had their own way of doing it, and as such each had a bit of a different look to it. Sometimes its incorrectly called Charcoal bluing. The later is actually it's own style of metal finishing, which predates carbonia.

This finish is created with a rotary retort, carbonia oil, and charcoal. And, just like over a century ago, I would guess the very few that provide this finish probably do it differently as well.

Carbonia blue is typically seen on double action revolvers, rifle and shotgun receivers, along with all the parts of a Colt Single Action minus the frame.

This is a wonderful finish with excellent wearing abilities and great looks.
