What is cold polishing of jade bracelets?

What is cold polishing of jade bracelets? Cold polishing refers to the polishing process of crystal bracelets. The processing of jade bracelets is roughly divided into 4 steps. The first step is to use a sleeve to make the bracelet ring. The second step is to shape it into a flat bracelet, a round bar, or a concubine. The shape must be trimmed first. The third step is to use a grinding wheel to polish the surface to be smooth and flat. The fourth step is polishing.

In the past, most bracelets were polished with sheepskin and cowhide. It is said that the old Burmese also used elephant skin, which was cut into round pieces and glued to a flat knitting machine. The polishing powder was then mixed into a paste and applied to the sheepskin. The bracelet was rubbed against it. Due to the friction with the sheepskin, a large amount of heat was generated, and the freshly polished bracelet would be particularly hot. This process is called hot polishing.

The first three steps of cold polishing bracelets are the same, except that leather is no longer used for the final polishing. Instead, very fine sandpaper is used. No heat is generated when polishing with sandpaper, so it is called cold polishing. The sandpaper used for cold polishing is all imported, and the polishing time is long and the damage is great.

However, this process can have a better polishing effect and higher brightness for jade bracelets with good water quality. Therefore, cold polishing is a more advanced and costly bracelet polishing process at present.
