2. Definitions.—For the purposes of this schedule

a. "pottery" includes earthenware, stoneware, porcelain, china

tiles, and any other articles made from such clay or from a

mixture containing clay and other materials such as quartz, flint,

feldspar, and gypsum ;

b. "efficient exhaust draught" means localised ventilation effected

by mechanical or other means for removal of dust or fume so as

to prevent it from escaping into air of any place in which work is

carried on. 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 or cleaning or

potteryware 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. "iow solubility glaze" means a glaze which does not yield to

dilute hydrochloric acid more than five per cent 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 filtrate shall then be precipitated as lead sulphide and weighed

as lead sulphide;

f. "sound 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

2. Efficient exhaust draught.—The following processes shall not be carried

on without the use of an efficient exhaust draught-

f.

all processes involving the manipulation oruse of a dry and unfritted lead

compound ;
