I actually read directions for using liver of sulphur several times. I also checked 3 different sources for directions. I followed safety precautions by using good ventilation. I was, and I emphasize was a liver of sulphur virgin, that is, until today. I thought I knew what to expect, but, guess what, I didn't! OMG! The smell was rank. I think I've smelled rotten eggs that smelled better than LOS. I'm getting a headache just thinking about the smell now. Then, I dipped my copper charms into the solution, and I couldn't believe what happened within seconds!

What happened to my pretty copper charms? ( I now understand why the directions said to use a small piece of LOS. I thought the chunk I used was small, but, I guess, it wasn't small enough!)
After my initial panic, I began to clean the copper using the directions I had read. I used my steel wool. I also tried a bit of CLR mixed with water, but don't tell anyone! I should have used more CLR, but, like I said, I was a liver of sulphur virgin at that time.

Batch one is a little darker than I would have liked, even with the intense cleaning I did, but as I look at them now, the charms don't look terribly ugly!

With Batch 2, I used a teeny, tiny piece of LOS. I liked the results a lot better. Clean up was easier, too.
Lesson for today:
When using liver of sulphur, think small, very, very small.
Also, don't try to patina as many pieces as I did. You can work faster.
Go to the hardware store and buy a metal brush.
This can only get better!
