Oxidation of silver


#1

I have been oxidizing my embossed and stamped silver pieces with liver of
sulphur. I am heating my piece and then applying the liver of sulphur. Of
course it is turning the entire surface of my piece dark and I am then
having to polish it so that the oxidation is only in the areas of relief.
My question is can this been done via tumble polishing or must it be done
by hand. I tried unsuccessfully to tumble the pieces after oxidized but I
couldn’t completely remove the oxidation from the nonrecessed areas. Does
anyone have any suggestions? Thanks alot!

I would sudjest switching over to Vigor gold/silver oxidizer and use a
steel to apply it to the silver just in the places that you actauly need
dark. A drill #64-76 can act as a pen for fine lines and an end brush for
larger areas. Steel reacts with the solution for a darker color on the
silver. If you want to oxidize gold you will have to warm the it with a
torch a little bit. Try this you wont loose as much detial. “A” Jim

Kristy- It sounds ridiculous, but to remove excess liver of sulfer patina
from the high areas of a piece, the best thing that I have found is a
little toothpaste- creamy , not gel. I rub it on the area with my fingers
til it removes the excess. makes your hands yucky, but your pieces smell
minty fresh-! :slight_smile: This is also what I tell my customers to do instead of
using silver polish, which will remove all the liver of sulfer. I have also
used tumble polishing type polish, on a damp cloth, but it seems to take
the shiny finish off more than I would like. Anne Stickney

I’ve tried tumbling and find that my oxidation is gone when I retrieve the
pieces from the tumbler. (Using Stainless steel shot . . .perhaps it’s
the wrong medium???) I’d love to get on how to do it without
destroying the look one wants.

I have had the same problem, one solution that worked for me
was using an extremly fine paint brush to paint the liver of
sulfur in to the resesed areas. If you try this be shure that
you dont drink to much coffee befor hand :slight_smile:
