The ornamental scrollwork on the frame is simple and effective, and is easy to construct, says Work, London.  The scrolls are attached to the frame by means of 3/16-in. round-head machine screws.  The leaf ornament at the

[Illustration:  Completed Fire Screen and Parts]

termination of the scroll is shaped and embossed as shown in Fig. 3.  The metal used for the scrolls is 3/16 in. thick by 1/2 in. wide.  The leaf ornament is formed by turning over the end of a piece of metal and working it together at a welding heat, and then shaping out the leaf with’ a chisel and files, after which they are embossed with a ballpeen hammer.

The center is made from colored glass of special make for leaded work.  The design is formed in the lead, of which a cross section is shown in Fig. 4.  Use care to give the lead a symmetrical outline.  The design should be drawn full size on a large sheet of heavy paper and the spaces to be occupied by the lead cut out so as to leave the exact size and shape of each piece of paper the same as wanted for each piece of glass.  These are used as patterns in marking the glass for cutting.  The glass is cut the same as ordinary window glass.  The glass, lead, border and special flux can be purchased from an art glass shop.

After the glass is cut, the work of putting the pieces together with the lead between them is begun.  Secure a board as wide as the screen—­several narrow boards put together will do and begin by placing one vertical side border, A, Fig. 5, and the base border, B, on it as shown.  Place the corner piece of glass, C, in the grooves of the borders, cut a long piece of lead, D, and hold it in place with two or three brads or glazier’s points.  The piece of lead E is cut and a small tenon joint made as shown in Fig. 6.  While the piece of lead D, Fig. 5, is held by the brads, the piece E can be fitted and soldered.  The soldering is done with a hot soldering iron and wire solder, using rosin as a flux, or, better still, special flux purchased for this purpose.  After the joints are soldered, the piece of glass F is put in place and the lead held with brads as before until the cross leads are fitted and soldered.  The brads are then removed, the glass piece as shown by the dotted lines put in, and the leads around it held with brads until the crosspieces are put in and soldered.  This method is pursued until the glass is complete, then the two remaining vertical and top pieces of border are put on and all corners soldered.

The leaded glass is held in the iron frame by means of eight U-shaped clips, as shown in Fig. 7.  A hole is drilled in the frame for the retaining screw, the latter being tapped to the base of the clip.  Special screws may be made with ornamental heads, as shown in Fig. 8, and used for securing the side scrolls and clips together.
