I know I can buy verdigris solutions (or just bury the piece in the cat box) if I want the green color , but I have an expensive entrance set that was finished in a "Venetian Bronze" patina. The patina is worn off of the areas where it gets frequent contact and the manufacturer (Baldwin) is not able to supply the materials to restore the worn area. The rep I spoke with mentioned that they use a copper sulphate process, followed by an oxidizing finish called Ebenol that gives it the rich dark color.
Does any one have any ideas for home recipes that can reproduce this patina - or something close enough that there is not such a stark contrast between the original unworn surfaces and the now-just-brass surface that I have on some areas?
