Hi,
Another method used to color metal was charcoal bluing, which is basically packing the parts in charcoal and heating to about 800 degrees for 2-3 hours. There is a bit more to it than that but those are the essentials. Below are parts for a late flint era English rifle. The engraving style is from that period.
