Silver plating. Matte and white.

[NikolayL]

Hi, I have a project of making 35 mm diameter watch dial. I plan to make it out of 0.5 mm brass plate by etching and then silver plating. Checked a lot of methods of silver plating, but look like all of them get you shiny and metallic appearance. I need matte and white surface. As white, as possible.
Looks like frosting can resolve the issue (heating and pickling in Sodium Bisulfate), but it works for sterling silver and plated layer might be not thick enough for that.
So the question is - what is the easiest way to get white matte coat of silver over brass?
Trying to avoid using poisonous and expensive ingredients...

To get matte plating, 2 methods:
Etching the base metal
Operating at higher current density than nominal.
Both need experimentation and optimization

How they make white silver dials at watch production factories?
For sure its silver plated brass.
May be they apply some chemicals after plating?
Something like Cream of tartar? Acid?

Silver tarnishes, they probably use something else.

Not under layer of finish.

I believe fine silver which is what you will be plating does not tarnish easily and as it’s enclosed it probably never will. As to how to get the matt finish once plated a gentle buffing with a plastic scrubber should get that finish as silver is very soft.
