MOUNTING A PAGE

Not infrequently, when old books are to be rebound, very badly damaged pages will be found, and these cannot be made strong unless they are mounted between some thin material. Either a Japanese tissue or chiffon may be used for this purpose. The chiffon is preferable, as it is more transparent. Pasting any material on only one side of a sheet of paper causes it to curl, and therefore a sheet to be strengthened by applying chiffon or Japanese tissue to its surface must be covered with the material on both sides. The page must, of course, be separated from the text in order to mount it.

When the paste is beaten to the desired consistency, a thin coating of it is spread over a glass slab, which must be larger than the page to be mounted. Then on the pasted glass is laid a piece of chiffon that has been cut to a size about one inch larger all round than the size of the page. After another coat of paste is spread over the upper surface of the chiffon and is smoothed out with the paste brush until the chiffon is quite flat, the page is laid on the pasted chiffon. Next, the surface of the page is pasted, over it a second piece of chiffon is laid and again the paste is smoothed out until the chiffon lies flat over the surface of the page. Then the three layers of material must be stripped off the glass in one piece. This is a rather difficult procedure and necessitates some practice, but with a little ingenuity it can be accomplished if the worker is determined and does not allow himself to get flustered. The three pasted layers will be sticky and moist and will require care in handling. They must now be hung over a clothesline or over a spreading clothesbar with wooden arms. The mounted page must be left until partly dry, when it should be taken down, placed between waxed boards, and put in a press for a half hour or so. Then the boards are removed from the press and the page is peeled from them. It is placed between freshly waxed boards and left under some pressure until it is thoroughly dry. Frequently it is advisable to change the waxed boards and increase the pressure while the page is drying. When the work is entirely dry, the projecting edges of the chiffon are cut off even with the line of the page, and after this is done, a sparing amount of paste should be run along the edges of the page with the finger to seal the chiffon with the page and prevent any fraying. The page should then be put between waxed boards and kept in the press for at least twenty-four hours.

The procedure when using Japanese tissue is practically the same as for chiffon, except that the mounted page, is not put between waxed boards but is hung up at once to dry.
