AIR GUN - Pottery, molds.
Air guns expel compressed air and have been adapted for use in the manufacture of pieces made by casting, to speed up the production. They are operated at low pressure round the edge of wet clay in small molds; this slightly dries it and allows the piece to be removed more quickly.
They are also used to clean dust from pottery or molds and to apply the glaze.
