FAST!
Make sure to have an chemical action stopper on hand as blackening is super fast and it's easy to overdo it.

Obsessed!
I am so beyond happy with this product. I will say if it’s your first time, use something to practice on a few times. Your silver will be black within seconds. After some practice, I am now able to get an absolutely amazing color on my previously extremely bright pieces that I didn’t wear simply because they were too bright and shiny for my taste. My jewelry now looks antique and mysteriously gorgeous. Use a little q-tip and gently brush over the desire areas until you like what you see. Ten out of ten!
