White (Manganese) bronze patina


#1

I’m working with the “white bronze” from Rio Grande, (61% copper,
17% manganese, 16% zinc) and looking for a dark patina. Anyone know
of a simple recipe that would work; or perhaps a product?

Have you tried any of the listings under ‘Bronze’ in the book
"Coloring, Bronzing and Patination of Metals"? I haven’t worked with
that bronze but the book should get you going in the right
direction. John

George,

I do not work with any other bronze than Everdur (copper/silicon)
but the patinas operate mostly on the copper part of the alloy as it
is what is reactive. Ditto for Sterling Silver verses pure silver.
Have you tired any “bronze” patinas on the manganese bronze?? The
zinc could also be reactive to some formulations. I would suggest
that you call or write/e mail Sculpt Nouveau in Southern California

Debbie and Ron know A LOT about patination of metals as well as
products that allow patination coloration of non metals. If you can
call them, 1-800-728-5787, ask for Debbie as Ron is hard to get to
the phone and the other folks often are not as knowledgable as
Debbie. I don’t work for them or anything like that, I am just a very
satisfied customer of many years. Tell Debbie that I told you to call
if you like but this is not necessary to get good help from them.

Or, I could/would try some of the many different patinas I have, on
some scrap pieces of your alloy if you wanted, but you would need to
send me some pieces of scrap as I have none of this alloy. I am in
Sequim WA, nearly due south of you, across the strait (we can see
the high rise buildings in Victoria on a clear day) so if you ever
came over to the States via the Coho ferry out of Port Angeles, you
could stop by with some scrap and we could see what we could get to
happen. What color(s) are you looking for??? Dark black and/or
brown are often the most easily developed, cold (not heat applied)
colors on Everdur, but LOTS of other colors and colorations are
possible with heat.

Hope this helps.

The website at Sculpt Nouveau appears to be inclusive ; I’m looking
for a black patina to accent the white bronze when polished so I’ll
give them a try; thank-you.
