Carborundum, when removed from the furnace, is a mass of crystals, of varying sizes, the greater number being of a size sufficiently small to pass through a sieve having 2,500 meshes to the square inch, and too large to pass through one having 40,000 meshes. These crystals cling together in so loose a manner that comparatively little effort is ...
