New friends, maybe you can offer some advise. It was necessary to do
a repair on this 12ct Victorian bangle bracelet resulting in a loss
of patina to the fretwork (see photo). Might anyone know a process to
replace the color loss? What was the likely original process?
Thanking you in advance. bg
Here’s how I would replace it to its former glory:
First I’d take off ALL the old patina using that rotten egg-smelling
dip recently discussed.
Dip it and rinse it immediately. Then steam to remove any stubborn
bits, redip if needed and rinse.
Then I’d use a chemical antiquing agent. I use Griffith’s Silver
Black Inactive Group - 54-5031 because it also works on
gold and works with this technique better than Liver of Sulfur which
goes bad after a while in the bottle, and never covers evenly.
(BTW, with the Griffith’s I pour as much as I need to blacken a
particular piece into a beaker of the correct size, then drop in the
piece (or place the piece in first and cover) the after the piece is
completely blackened, I pour the solution into another old
Griffith’s bottle, and reuse that solution over and over until it
stops working, then discard it rather than polluting the new bottle
with the used solution.)

BGOLDPAWN, I got the jpg of the piece via the e mail from PAF
DVORAK. What is the metal? If alloyed gold, what is the karat of the
alloy? If not a gold alloy, do you know what the actual copper(?)
alloy is that was used? What is the actual color of the patina that
you are after, black or brown or??.
