Help on pink gold plating

+++

I have had a difficult time getting a dark pink color out of the Red gold plating solutions we have tried. I have seen this color on some antique English pieces of jewelry but cannot seem to come up with it using materials available today. Does anyone have a solution for this problem, or know where I can get several pink gold plating solutions to try?

Thanks,

Hi, Joseph. Al Weisberg's "Gold Plating" chapter in the Metal Finishing Guidebook has a lot to say about what plating parameters to vary to bring out different tones of reds and pinks, and should be worth a read for this. I haven't read Reid and Goldie's Gold Plating Technology => myself, but it sounds like it might be just what you need. Finishing.com's supporting advertiser, Technic, is probably the major supplier of precious metal plating processes, and can probably provide some pink gold plating solutions. Good luck.

Q. Hello

I'm trying to achieve a "rose gold" plating over silver.

I was told that the process is as follows

-electrolytic degreasing
-Phosphor copper bath
-Yellow gold acid bath
-Yellow Gold alkaline bath
-Final decorative bath of pink gold (acid)

This procedure would be correct?

Thank You
