摘要： An abrader for use in mirror polishing of glass comprises a porous cured unsaturated polyester resin and zirconium oxide or cerium oxide or red iron oxide. Desired mirror polishing of glass is effected by grinding the glass surface with this abrader under continued supply of water or a cutting oil to the interface of grinding.
