How to make metal jewelry black

The metal jewelry is dark in the crevices, which serves to accent the surface embellishments of the jewelry. If you don't want to wait years for your own jewelry to naturally oxidize, you can do it easily in a matter of minutes.
Firstly, find a hear-resistant glass bowl, and pour into a 1/4-inch diameter piece of Liver of Sulfur. Then Pour a cup of boiling water into the glass bowl. Break up and completely dissolve the Liver of Sulfur with a wood skewer in the hot water.
Secondly, drop the jewelry into the mixture. If you have brass jewelry, you’d better take the longest time to blacken. On the contrary, if the metal jewelry made with copper, you have to make it soak for the shortest time. Sterling silver is somewhere in between. Watch the jewelry for the depth of oxidation you want on the piece of jewelry. Oxidation of any of these three metals takes just a matter of minutes.
3. Take the metal jewelry out of the solution and rinse under warm, running water. Dry off the jewelry.
4. Use a piece of steel wool to remove the black oxidation from the top surface of the jewelry, leaving it in the crevices.
With this method to blacken metal jewelry, they must have a new feeling when you wear them.
