No draught shall be deemed efficient which fails to remove effectively dust or fume generated at the point where dust or fume originates; (c) "fettling" includes scalloping, towing, sand papering, sand sticking, brushing or any other process of cleaning of pottery-ware in which dust is given off; (d) "leadless glaze" means a glaze which does not contain more than one per cent of its dry weight, of a lead compound calculated as lead monoxide; (e) "low solubility glaze" means a glaze which does not yield to dilute hydrochloric acid more than five percent of its dry weight, of a soluble lead compound calculated as lead monoxide when determined in the manner described below. A weighed quantity of the material which has been dried at 100 degrees centigrade and thoroughly mixed shall be continuously shaken for one hour at the common temperature with 1000 times its weight of an aqueous solution of hydrochloric acid containing 0.25 per cent by weight of hydrogen chloride. This solution shall thereafter be allowed to stand for one hour and then filtered. The lead salt contained in the clear filtered shall than the precipitated as lead sulphide and weighed as lead sulphate; (f) "ground or powdered flint or quartz" does not include natural sands; (g) "potter's shop" includes all places where pottery is formed by pressing or by any other process and all places where shaping, fettling or other treatment of pottery articles prior to placing for the biscuit fire is carried on. 3. Efficient exhaust draught.- The following processes shall not be carried on without the use of an efficient exhaust draught:- (i) all processes involving the manipulation or use of a dry and unfitted lead compound; (ii) fettling operations of any kind, whether on green ware or biscuit, provided that this shall not apply to the wet fettling, and to the occasional finishing of pottery articles without the aid of mechanic power; (iii) shifting of clay dust or any other material for making tiles or other articles by pressure, except where- (a) this is done in a machine so enclosed as to effectually prevent the escape of dust; (b) the material to be shifted is so damp that no dust can be give off; (iv) pressing of tiles from clay dust, and exhaust opening connected with each press. (This clause shall also apply to the pressing from cIay dust of articles other than titles, unless the material is so damp that no dust is given off); (v) fetting o{tiles made from clay dust by pressure, except where the fettling is done wholly on, or with damp material. (This clause shall also apply to the fettling of other articles made from clay dust, unless the material is so damp that no dust is given off); (vi) process of loading and unloading of saggars where handling an manipulation of ground and powered flint, quartz, alumina or other materials are involved; (vii) brushing of earthenware biscuit, unless the process is carried on in room provided with efficient general mechanical ventilation or other ventilation which is certified by the l11spector of Factories as adequate having regard to all the circumstances of the case; (viii) fettling of biscuit-ware which has been fired in powered flint or quartz except where this is done in machines effectually prevent the escape of dust; (ix) where c leaning is after the application of glaze by dippling other process; (x) crushing and dry grinding of materials for pottery bodies an saggars, unless carried on in machines so enclosed as effectively prevent the escape of dust or is so damp that no dust can be given off; (xi) sieving or manipulation of powered flint, quartz, clay grog or mixture of these materials unless it is so damp that no dust can be given off; (xii) grinding of tiles on a power driven wheel unless an efficient water spray is used on the wheel; (xiii) lifting and conveying of materials by elevators and conveyors unless they are effectively enclosed and so arranged as to prevent escape of dust into the air in or near to any place in which persons are employed; (xiv) the preparation or weighing out of flow material, lawning of dry colours; colouring, dusting and colour blowing; (xv) in mould making unless the bins or similar receptacles used for holding plaster of parts are provided with suitable covers; (xvi) the manipulation of calcined material unless the material has been made and remains so wet that no dust is given off. 4. Separation of processes.- Each of the following processes shall be carried on in such a manner and under such conditions so as to secure effectual separation from one another, and from other wet processes :- (a) Crushing and dry grinding or sieving of materials, fettling, pressing of tiles, drying of clay and green ware, loading and unloading of saggars; (b) All processes involving the use of a dry lead compound. 5.
