In the workshop different kinds of glue-pots are used according to the quantity required. For workshop use the ordinary glue-pot (Fig. 480) may be used. This has an outer and an inner vessel, as shown in the section (Fig. 481). In large workshops, where glue is used in quantity, and steam-pipes are laid on for heating purposes, a tank constructed as shown in Figs. 482 and 483 may be used. It is made of 1/4-in. plate iron or steel, with four holes (c, Fig. 483) in the top, large enough to accommodate buckets or specially made glue-pots; d is a steam-pipe carried nearly to the bottom of the tank, and e is an overflow pipe to carry away the waste water produced by the condensation of the steam. A small hole must be provided at f, or the overflow pipe will syphon all the water out of the tank. A draw-off tap at G facilitates cleaning out, or supplies hot water. When required for use, the tank is filled with water and the steam turned into it, which will cause the water to boil. If steam-pipes are not laid on, the glue-tank may be constructed as shown in Fig. 484, and heated with coal or waste wood.
