Okay, here we go...
Oxidizing Bronze Jewelry Wire, specifically Wrapit Jeweler's Bronze, dead soft wire. To darken this wire, I used ammonia and found it to work pretty well and I like the look it gave. First remember to work under good light, using gloves and in a well ventilated room or near an open window. Ammonia has a strong potent smell so be careful with it.
2. In the smaller container, fill it about 3/4 way with simple house ammonia and place it inside of the larger container.
3. Put your jewelry piece inside the larger container along side the ammonia container, careful not to get it splashed on.
While the vinegar does a good job of removing the tarnish, it doesn't give it that nice 'shine' and so this is where the steel wool brillo pad is needed.
7. To preserve the highlighted effects and prevent it from gaining more tarnish over time, coat your finished jewelry in either bees wax or I've read a floor wax will work also.

I have yet to try the bronze wire in this solution but will be doing that soon also. ;)
3. Follow their simple instructions printed on the bottle and the results will be great. It works in a matter of 'seconds', happening very fast, so I recommend that you 'dip' your piece until you get the patina level desired.
Again, keeping safe practices in mind, use gloves, use a spare piece of wire as a 'dipping tool' which you can attach your jewelry piece onto. Don't get your hands directly into the solution and work in a well ventilated area or near an open window. If you don't know already, then know now, that the liver of sulfur smells exactly like a batch of rotten eggs, so be prepared for it. The Patina Gel provided by CoolTools is a great way to work with liver of sulfur as opposed to the 'chunk' dry pieces. I've used that before also and it's not as great as this well designed, clean bottled gel form.
This marvelous heart isn't quite finished yet but will be available in my etsy store along with many other pieces when they are done. I currently offer a variety of wire wrapping tutorials, which you should check out in the meantime. Have a wonderful and creative day!
