Green copper patina #2

1 Tbsp ammonium chloride (sal ammoniac)(shave it off of a block)
1 Tbsp salt
1 oz. ammonia
1 qt. water

Mix in a plastic container using warm water, it will help dissolve
the particles. Use of bottle water is recommended but tap water will
work. The copper must be clean and dry. Spritz the metal with a
pump spray until it is uniformly wet with the mixed solution.
Allow it to dry naturally in a warm dry spot. Trying to speed up
the process will result in a flaky patina. When dry, respray and
again allow to dry. Repeat process at least four times.

Remember to take the proper precautions when working with chemicals.

Ok, I'll bite. Where does one readily get copper nitrate or ammonium cholride AND NOT get put on the NSA's "let's tap this guy's internet and cell phone" list?

Hello,
Ammonium Chloride can be found on Ebay. Not sure about copper nitrate. I doubt, unless you try buying it by the truck load that you'll get into much trouble.
