I really prefer the liquid Liver of Sulfur over the solid rock form because you don't have to wait for it to dissolve. Also, every time I have purchased the rock form, it has expired before I had a chance to use it all. Liquid Liver of Sulfur will weaken over years but if you keep it super airtight and in a cool dark place, it will extend the shelf life. Personally, I haven't seen it happen (my bottle has lasted a long time) but in theory, there is the potential that it could weaken over time.
This is a 4 ounce bottle of liquid concentrate. You will be diluting only a small amount with water . The bottle has instructions for using it with Copper, so we have included our own instructions with the bottle for using it with Silver.

Be sure to watch the video. It gets the job done. It works very quickly. I left my copper in for a very short time and it left it with a thick layer of black which only steel wool would remove. The next time I used it I 1 layer at a time on and it also turned very quickly. Have your supplies close to use. I actually wanted a more colorful color which I obtained by using a hot boiled egg smashed in a bag. Beautiful color on copper. Be sure to use just alittle rather than more of this product you can always go back and add more.
