Re: Help! Copper Patina Question
I use liver of sulfur a lot. I don't know how long it lasts but do know it's very unstable in light, keep it in a dark place when you store it.
What problem are you having? The copper must first be cleaned thoroughly or the liver of sulfur will not adhere. Also, you need to make sure you are mixing the correct amount of water with it; the brand I use is liquid, made by St Louis Crafters Co. Mine calls for something like a tablespoon of liver of sulfur per cup of water.
I'm guessing the issue you're having is due to the age.
By the way, I like your work. I hope to see the relief you are working on.
