I don’t know of a chocolate colored gold alloy, but various tinctures
of Iodine solution will create various shades of brown when applied
to gold (Gold Iodide). Very persistent and durable…

Anupam,

My understanding is that the chocolate brown gold is a proprietary
coating on the gold and it is not available for sale.

Hi Anupam,

The master alloy you refer to may not exist in a practical sense. We
have tested numerous items and all have been coated, I suspect in a
plasma coating technology, which is very long lasting.

Hello Anupam, There are many approaches for making coloured gold;
Electroplating, Oxidation, Amorphous carbon by CVD, Patination,
Physical Vapour Deposition of brown Zrnitride. Depends what method of
manufacture you are following.

Is the bulk metal brown? If not what is the process for turning it
brown?

It is a proprietary formula. We make the alloy and you can create
10, 14 or 18K brown gold by adding appropriate amount of gold to the
alloy.

Again, is the bulk metal brown or is some treatment process required
to achieve a brown color on the surface?

James, there are alloys out there that will give you a brown gold
one such recipe can be found in the archives, to save you some time
here’s a link to the relevant posting:

https://orchid.ganoksin.com/t/blue-gold!

the brown gold is number 10 from the bottom.

So if there is one formula then there HAS to be others… Oh yeah I
haven’t tried any of these personally so YMMV greatly.

Goodday,

how does one buy or acquire the formula for making 18k Gold? Sounds
interesting…and how about 16K?i read an article that says the
jewellery turns green…

best regards,
D.

Yes, the bulk metal is brown and there is no treatment process.

Are you sure the gold will be brown? at this ratio, to our knowledge
it will be completely white and it is not castable. To much shrinkage
and it will crack. We know. We did tested it. Cheers.

Like I said in the last line of my email, I hadn’t tried them so I
can/could only go on what the original poster said, hence the “YMMV
greatly” bit.

I’m confused. I’ve read the archives about if there is a brown gold
alloy or not. I’ve contacted UPM and they say it is a type of
plating. Can someone make it a little more clear?

Hi Kirsten,

About a month ago there was a discussion about brown gold and the
company called Goldcast said, yes they had a workable alloy.

I jumped, and sent my credit card number and started discussion.

Well, all that happened was that I got a shifty reply that the
patent lawyers were still ‘busy’ and they would get back to me…
Right.

There have been several claims of malleable coloured alloys on this
list, but they all have been BS, I am afraid.

There is, however one hope left. I have been in contact with some of
my extra-terrestial friends and they said they would come back to me
just as soon as they have won their inter- galactic war…

Just the other day somebody asked me how to do this - I told them
the truth, that I didn’t know… But a simple Google brought up
the answer - it’s neither alloy nor plating, it is the chemical
vapor deposition of rose gold. Plating in the loosest sense,
perhaps.

I called some experts? and there is a malleable chocolate brown
gold… Hershey’s with or without nuts.

Kristen,

I’ve found a whole list of colored gold alloy formulas. I have not
personally tried them. Let me know if you want the whole list,
however, here is the formula for brown gold:

https://orchid.ganoksin.com/t/blue-gold!

Brown: 18k Pure gold-75%; palladium-18.75%; silver-6.25%
