As a loose abrasive grains. Through pressure blasting, emery (relatively coarse grain size) could used to cleans tone and concrete, clean metal castings, prepare surfaces for painting, and etch glass and plastics . It is mainly used for sawing stone, rough grinding plate glass, and surfacing stone. Emery (fine-grained powders) could charge brass tube which drilling small holes in glass, porcelain, gemstones,ect. Emery cou cast into the treads of steps and ramps to increase traction.
As a bonded abrasives. Emery are bonded and pressed or molded into a wide variety of bonded abrasives such as grind ing wheels, honing stones, and tumbling media.
