Sand-dusters
Flat, round vessels of block-tin, with fine perforations on one of the flat sides. They are used largely among hardware and stove founders for dusting the joints with parting-sand, instead of using the hand for that purpose. See PARTING; PARTING-SAND.
Sand-floor is that part of the foundry floor usually devoted to the production of castings in green sand, many of which are moulded in the sand-floor itself, and termed "sand-floor," to distinguish it from the dry-sand and loam-work floors. See FLOOR-MOULDING; BLACK SAND.
