For home use the glue may be melted in a cup or tin placed in a saucepan of boiling water. A serviceable glue-pot is made as follows: Get a cocoa or mustard tin, and pierce two holes in it opposite each other, about 1 in. from the top; get about 8 in. of tinned wire and run it through the holes, the wire resting on the edges of the saucepan. Another device:—A disused golden syrup tin, about 4 in. by 4 in., is very suitable for the outer pot, as it has a ring round the top, inside, about 3/8 in. wide, on which the flange of the inner pot may rest. In each side of this tin, about 1 in. from the top, pierce a hole, and bend a piece of iron wire into a half circle, place the two ends into the holes in the tin, as shown in Fig. 485, and clinch them over inside. The inner pot may be made from a coffee tin, 3 in. in diameter by 6 in. deep. This, of course, is too deep, so, scribing a line right round the tin 3 in. from the bottom, cut from the top downwards a number of slits 3/4 in. apart to the line. Bend all these pieces of tin, except one on each side, at the line to right angles with the sides of the tin, thus forming a flange about 3 in. wide. Cut down this flange to about 1 in. wide, and the two upstanding pieces to 1 in. high, rounding at the top. In each of these two pieces pierce a hole, and get another piece of. iron wire, bent as before, but slightly shorter; put each end through the holes, clinch over, and the pot is complete, the inner pot appearing something like Fig. 486. Another device:—Fig. 487 shows a 2-lb. syrup tin A, a condensed milk tin B, and pieces of wire C, and explains itself. If the water should boil over it cannot get into the glue, and, when using, the brush is wiped upon the wires C, and that does away with the accumulations of glue commonly seen on glue-pots. A different kind of inner pot is made as follows:—A 2 1/8-in. round hole is made in the lid of a 2-lb. syrup tin, and the ring thus made is put over the top of a 1/4-lb. round mustard tin, and soldered to it at the distance of 1/2 in. from the top of the tin. In running the solder round a small space may be missed to allow the steam to escape, or a hole may be made in a convenient place. The handle may be made by cutting off the screws of two screw-eyes, making holes in the sides of the syrup tin, and soldering them in. The lid of the mustard tin may be used to cover up the glue when not in use. Another device:—Take al piece of suitable wire A (Fig. 488), and make three loops B at equal distances, according to the size of the vessel used. This is placed at a convenient height on the vessel C, so that it well clears the bottom of the vessel D, in which it is placed. A piece of wire E is then placed over the top, the two ends being bent down to come between the wire circle A and the inner vessel C, preferably between two loops as shown. All is then twisted up till it grips the vessel quite tightly. The vessel C is then placed in the outer vessel, and the loops are turned down equally on all three sides, thus keeping it firmly in the centre, the two ends being bent flat against the inner vessel to be out of the way and to prevent the inner vessel floating. Of course, the two ends could form the third loop if desired. The arrangement is made in a few minutes, and the inner vessel is not perforated at all. In the illustration cne loop is not shown, it being at the back of vessel C. The wire E is for cleaning the brush, which may be put either in the centre or at one side.
