Tibet is not a place to produce beeswax, because beeswax is one of the seven treasures of Buddhism, so there are many in Tibet; Beeswax, a variety of amber, is called beeswax, which is opaque or translucent. It is an amorphous substance with no fixed internal atomic structure and external shape. The fracture surface is usually shell-shaped, and the refractive index ranges from 1.64 ~ 1.89, so birefringence is not applicable. According to the physical test, the specific gravity of beeswax is between 1.05- 1. 10, which is only slightly larger than water. It is a precious ornament.
