"Composition, pulp, methods for polishing and to treat a superfu00eccie and to prepare a polishing composition not expanded pearlite ore.Device for directing a polishing composition of pearlite ore not expanded under a gas stream against a superfu00eccie a piece of work.Combination of a polishing composition and a material load, and material for polishing off my teeth. " The polishing composition is shown a pearlite ore not expanded.The composition comprises a base material having grains of expanded pearlite ore not a distribution of particle sizes are selected as a function of the fracturing of the grainsNon abrasive force applied on the base material.The selected particle size distribution includes a significant volume of grains of expanded pearlite ore not having an average particle size (d ~ 90 ~) within a range ofApproximately 101 GM to about 229 109 M.The base material is responsive to a force applied in the same during abrasive polishing resulting in fracturing of the grains of perlite ore continued not expanded to give a compositionWill end with a sufficiently low level polishing surface under the above abrasive strength making it suitable for use in polishing.Also shown are compositions for polishing acrylic dentures and surfaces of tube CRT using the polishing composition of pearlite ore not expanded and methods for polishing of the sameThe.
