Default Patina recipe

Unbelievable.
No one has posted to this category? I'm disappointed in you guys.
Ok. joking aside,
I have a recipe for home made patina to turn copper green-- providing you live in a wet, humid environment. For those in dryer environments, it takes much, much longer than many wish to wait.
ready?

1 gallon of water.
2 tablespoons salamoniac-- yes, good old sally.
2 tablespoons salt-- yes plain old table salt.
2 tablespoons ammonia. Yes, the really digusting smelly stuff, sorry.


Mix it all together and you have a tinner's dream come true.
I can tell you from personal experiences that it really does work.
1- along the coast of southern calif. it takes 45 seconds to turn the copper green. Yes, less than one minute.
2- In the desert just east of Lake Tahoe, it taskes 45 minutes to 2 hours to turn the copper green.
It's a humidity thing.
For those who are curious, and willing to try, play with the amounts and I'm certain that you'll obtain better mixtures.
I obtained this recipe from the folks down at San Clemente Sheet Metal shop. So, Mike if you're reading this, please tell Gary thanks again.
It's been a real godsend.

FYI.
Copper left to itself in desert environments has a tendency to turn black-- personal experience.
SteveB.
