Patina recipes
Alison
Does anyone have any patina recipes they'd like to pass along?
I mostly work in sterling and fine silver, but would also like to try
patinaing copper and brass. I know how to achieve the black finish
with liver of sulfur, so I'm looking to get other colors such as iridescent
shades of purple, blue, green, gold, etc.
Thanks,
Alison

One of the things I do quite effectively with copper is simply use my
torch (mildly oxidizing flame). While the pattern is irregular, it can make
some
beautiful effects. For those of you without a torch, Chicago Tool makes a cheap
one
(<$5) which works on lighter butane.

A rudimentary source for patina recipes is a book titled "The
colouring, Bronzing and Patination of Metals" by Richard Hughes and
Michael Rowe. The book is available on-line from Amazon books. The
recipes are standard fair if your somewhat chemically inclined.

I wish I knew what I did to get this, but I use a bucket to rinse such things
as stuff coming out of pickle, stuff coming out of the tumbler(I use Dawn) and
rinse items out of the ultrasonic (I use parson's sudsy lemon amonia). So I
had this half bucket of water that I have been rinsing these things off and
pulled out 5 pieces of silver from my tumbler and dropped them in the bucket.
I went to bed and the next morning I noticed the pieces were dark (my thought,
OH crap, what happened) I pulled them out and I swear they were the most
beautiful shades of royal blue, purple and fucia. Looked just like titanium.
When put back in my tumbler, it removed the color. Sure wish I knew what I
did. I could make my fortune! Joy

Probably not. Those colors on silver are such thin and fragile layers that they
are almost impossible to preserve. Sometimes, you'll get them with very dilute
liver of sulphur, or other, milder sulphur compounds. Also, over time, they
loose their bluish etc. tints, and become grey to black. Doesn't take long
either.
But here's one variation that has seemed more durable. On occasion, I've used
Kumbo to decorate areas of my silver with very thin gold foil, almost leaf. The
process I'm useing requires me to then solder these pieces after the Kumbo is
applied, so they get heated hotter than the Kumbo process, almost annealed
again. In the process, apparently a significant amount of silver migrates
through the gold layer. Not enough to really affect the color of the gold, but
enough so that when I then use liver of sulphur to oxidize the silver portions
(the pieces are gold against the blue/black gunmetal color you get when you use
a wet brass scratch brush to burnish the liver of sulphur patina) the gold is
affected by the liver of sulphur as well, often producing subtle highlights of
purple, blue, and a lovely dark gold color. I've some of these pieces from as
much as 12 years ago, and the colors have stayed pretty much intact. You do
have to be careful with it, as you can easily buff or even burnish it off again,
but at least age and atmosphere alone doesn't remove the color.
Hope this helps.

Howdy,
The article below was posted to the Jewelry Design Mailing List by
Charles Lewton-Brain. Hope it helps.
Remember that all patinas are toxic and irritant and should not be
worn next to skin unprotected. There is an article of mine on cupric
nitrate patinas at:
http://www.ganoksin.com/borisat/tree.cgi
under the 'surfaces' heading. Also the Artmetal site and the Metal web
news
have some patina info, as well as otheres:

I would also recommend this book... it deals with the colouring of
many metals and has well produced photographic samples of the patinas
produced..
the isbn for those who are interested is 0903798603
and it is/was published by the crafts council
all the best

What is Kumbo process? I am a goldsmith and have never heard of this term. I
am always interested in obtaining color or patinas on my work but it's hard
with gold. I was interested in the "Patina recipes" that wrote. Thanks
