I have used Blacken-It fairly successfully to turn brass photo etch , well, darker in the charcoal direction, but is there some chemical mordant which will turn it towards silver? maybe a question for a gunsmith? would barrel bluing offer a color somewhere between charcoal & silver just for a variety? thanks

My experiences with rub-on or liquid gun blues is that they turn metal blue-black (usually mostly black) but are never a perfect match for a chemically blued color. I can't imagine they could produce a color with any silver tint. -- Russ

Non-ferrous metal can be dyed silver with chemical nickel, but this is a very complicated difficult process.

Addendum: That would color silver. It would be much easier to nickel plating.

Not to highjack this thread, but are there any home made solutions that can blacken (or turn dark brown, but not bluish) brass, bronze or copper?

Blue-black is usually the result of steel as a substrate. All non-ferrous metals are chemically colored brown-black.

They are in San Diego or Southern California and will ship to you and you can usually find it at metal supply centers they have both ferrous and non  colorants and also water based too for the more Eco friendly modeler.
 l like their Japanese brown for the aged copper, and their blacken it solution is a fraction of the cost and much stronger than "Blacken It" brand
