Question: I heard that the vacuum plating in the furnace is not easy to fade, so can the silver jewelry use vacuum plating to keep the color longer? Answer: The temperature of vacuum plating in the furnace is as high as 800 degrees. Only stainless steel jewelry (without diamonds) can be operated, while silver jewelry cannot withstand such a high temperature and will melt. In addition, although the color retention period of the vacuum plating in the furnace is longer, it is more troublesome to adjust the plating color, and the waste is relatively large, so the color is relatively small. Generally, only 18K gold and rose gold are more common. The information comes from the Internet, please contact if the infringement is involved.
