PURPOSE:To make it possible to simply and largely manufacture an inorganic hard body having a fine lustrous surface by using a barrel-finishing medium consisting of flexible synthetic resin and inorganic polishing material. CONSTITUTION:A solid product consisting of flexible synthetic resin and inorganic polishing material is used as a barrel-finishing medium, and added into liquid such as water or the like, and then used for the barrel finishing of glass, ceramics and an inorganic hard body such as a crystal. Thus the inorganic hard body having excellent weight accuracy and a fine lustrous surface with no struck or scratched flaw can be inexpensively end largely manufactured. |
