A. Simple patina for silver:
30 gm copper sulphate
15 gm sodium chloride
1 dl water
Immerse object in solution!

Q. What if the item is a very large tray? Also where do you get the products?
Thanks

A. Hi Dianne. Please remember that an internet forum is a gigantic "one-room schoolhouse" where all of us are constantly overhearing things that are below our grade level in that subject and above it. Although copper sulphate ⇦this on eBay or Amazon [affil links] (root killer) and sodium chloride (table salt) are not strong noxious chemicals, the general idea of mixing chemicals is not for the casual reader but for people who are trained in it.
An easy and safe way to darken silver is to just break up a few hard boiled eggs, scatter them on your tray, cover with plastic wrap, and leave for a few hours. But don't be mad at us if the effect isn't what you were going for -- everything including art benefits from experience :-)
Good luck.
