Sawdust

Sawdust is composed of the small particles of matter which are produced in the act of sawing, but the word is used in a narrower sense generally to denote the dust produced by sawing wood. This dust is used in many industries, as, for example, for the manufacture of oxalic acid, for polishing by jewellers, for the making of bois-durci, for packing by furriers and perfumers; and the coarser kind, such as comes from the old-fashioned handsaw, is of great use for packing ice.
