Oxidation of silver

Silver, a chemical element, silver is a soft, white shiny transition metal with the highest conductivity, thermal conductivity, and reflectivity in all metals. Silver is not susceptible to corrosion by chemicals and has long been considered a precious metal. Silver is more abundant than gold, used as a coin in modern currency systems, and sometimes even used with gold. Silver is also used for solar panels, water purifiers, jewelry and accessories, expensive cutlery and utensils (silverware), and silver coins and silver bars can also be used for investment. The characteristics of silver, its chemical properties worse than copper, at room temperature, and even when heated does not interact with oxygen in water and air, but the home can become dark in the air and lose the silver-white luster. However, I want to speed up the oxidation of silver and make black silver directly. Black silver is also a production technique that many jewelry designers use. Accelerate the oxidation rate of silver, and then silver will naturally turn black. After darkening, people will have a kind of old effect. There is a feeling of retro jewelry. After buffing, there will be a different effect, that is, a kind of treasure is the same as their own excavated.

Colorless or light yellow liquid with pungent odor. Available chlorine content is 5.5-6.5%. It is widely used in the disinfection of hotels, tourism, hospitals, food processing industries, and households. 3. Sulphur soap is heated in water and put into silverware. This can also be achieved. But for a long time. 4. Silverware can be placed in the egg solution. Silver will naturally oxidize after waiting for a while. 5. The slowest natural oxidation, silver will naturally oxidize to produce black after being worn on human body for a long time.
