The first waxing is to wax and polish the blank when processing jewelry. The surface of jewelry is rough because the wax block contains polishing powder with different thickness, so as to prepare for beautifying the surface or electroplating gold.
The second waxing is when the jewelry leaves the factory, adding a protective layer to prevent the jewelry from oxidation.
