This ones from the no brain left dept.
Years ago I did a finish on silver leaf that looked like dark lead.Anybody know how to do that.All I remember is that it was a 2 part chemical process.You put one chemical on and then when you apply the next one it turned the silver into a beutiful dark lead patina.
Thanks Roderick
P.S Thanks for finding my check John!Gtta love those Englishmen

The best way to turn silver dark is with sulpher - as in egg yolks and/or mayonnaise. The book Coloring, Bronzing and Patination of Metals says to wipe it with ammonium sulphide using a soft cloth then rinse and let air dry. I don't know of a standard patina that has ammonium sulphide in it.
Or you could by-pass the silver and mirror it with lead sulphide directly (shameless self-promotion - sorry - it just slipped out)

Thanks for the reply Sara.
I will try your suggestion.I've received a little more info on the "Lead finish I discribribed.After apllying silver leaf with oil size.Wash on Cupric Nitrite/ ammonium chloride first and then barium sulfide second without rinseing between.It produces a beutiful lead finish.This does not work on water guilded (glass ) SILVER ,only oil guilded.It would be nice to try it with chemical silver mirroring .That might work.As soon as I receive the ratios I will let you know.
