I've gotten a lot of questions about different techniques or advice on how you get that really dark patina on silver. So I figured this will be my first "secret sharing"!
What I have found to work the best is Liver of Sulfur. It seems to hold up better than Black max and those other things. What I do is to tumble my jewelry well to make sure it's clean or I use rubbing alcohol and then just wash it with hand soap or dish soap and rinse well. The key is to not touch the jewelry as it's clean. I always wear plastic gloves. Also cause I don't think yellow stinking fingers is very attractive. And neither does David :o)
I prepare my liver of sulfur using hot water and a couple of chunks of loS (make sure you store that stuff air tight so no moisture can get in and it will last forever! And store it somewhere dark). Don't make it too hot or too strong as the patina will flake off. It's better to keep it at a medium temperature and instead you can let your pieces sit in hot water before you put them in the solution. And here's really the trick! Don't let them sit in the solution too long. I put my things in for maybe 20-30 seconds. Then I take them out and rinse them with hot/medium water. I put them back in for another 20-30 and then out again and rinse. Keep repeating until you get it as dark as you want it! You will get a rainbow of colors before it get to that dark black stage. It's quite fun to watch!
After you have your really dark pieces, don't be afraid to throw them in the tumbler for about 15 minutes. Only use Dawn original soap and no burnisher and you'll get a really shiny dark finish.
To achieve that really black look I use some Renaissance Wax as a finish to protect the patina more (I obviously don't rub that on any ear wires as you don't want wax in your ears!). As with any patina wear and tear will eventually wear off the patina but if you follow these simple guidelines (especially the tumbling after finished oxidization) you will get the darkest and longest lasting patina!
