A piece of iron wire about No. 24 is then placed around the box and twisted tight enough to hold the corners in place while being soldered, [Figure 19]. Borax and solder are next applied and the soldering done as described on page 63. In this case, however, all of the corners should be prepared at the same time for soldering. If but one corner is prepared and soldered, the heat necessary for soldering causes the copper oxides to come to the surface at the other corners which must be removed before they can be soldered. This is remedied by coating with borax and placing the solder at all corners before applying any heat.

After the soldering is done the box is pickled. Surplus solder is next removed by filing. The box is again placed over the iron block which is held in the vise; the corners and bottom edges are squared up, using the round end of hammer shown at No. 2, [Plate 2], and the top is filed off level. This completes the body part of the box.
The cover is made in the same way as the box. Much care must be taken to have the pattern carefully and accurately drawn so that when the cover is finished it will fit closely to the body. The design, if there is any, whether it is embossed or enamelled, must be carried out before cutting it to size.
Box No. 2, although of different proportion, is made in the same way as No. 1.
