Anna, I do not think the color shift is from a dip tank. It is a rust reblue that was probably done by the jeweler who did the engraving and the salt solution had some copper, or other heavy metal salt, in it to accelerate the rust bluing process.
THe second blue has changed color over the years, but is a charming part of the history. |
