I am making some mixed metal (copper & silver) pieces and want a
rich, brown patina on the copper - more of an aged, antiqued look. I
have read about Baldwin’s patina and also about a recipe using ferric
nitrate. I don’t want a blackish brown and I don’t want to patina the
silver, although I could remove the silver patina if I have to.
Also, does anyone in the Los Angeles area know where to purchase
chemicals like ferric nitrate?
Thanks for your help
