Abrasives

Media used for blasting, grinding or polishing. Abrasive materials are either in loose form or formed together into wheels, files or bricks or adhered to cloth or paper with resin or glue. Natural abrasives include sand, baking soda, garnet, emery, flint and corundrum. Metallic shot, grit and plastic material are also used as abrasives in the cleaning of castings and surface preparation.
