Default Re: Restoring Brass Etched Labels

I think what happens for the originals is that you start with a piece of brass. Often nickel plated. You then photomask the bits you want brass or silver and then acid etch the rest to give the relief. The etched bit is then either chemiblacked or painted and then the resist is washed off - it will take the surplus paint with it.
