No.2B

The surface brightness and flatness of no2B is better than no2D. 

then through a special surface treatment to improve its mechanical properties,

No2B could nearly satisfy comprehensive uses.

No.3

Polished with abrasive belt of git#100-#200, have better brightness with 

discontinuous coarse stria, used as inner and external ornaments for building, 

electrical appliances and kitchen utensils etc.

No.4

Polished with abrasive belt of grit #150-#180,have better brightness
