Books in leather reliures or with leather koreshkami demand special attention to themselves.

Such books are very sensitive to humidity of air and presence in it of connections of sulfur. So, at storage in with humidity of air below 40 % the leather of reliures becomes rigid, is deformed and rassypaetsja, and at the raised humidity grows mouldy. In a word, the leather of book reliures demands special leaving.

From time to time look through books — whether insects were got in them: bugs-grinders, kozheedy, mol, book vosh, etc. One of them eat a paper, others prefer reliures, lichinki the third not away to regale on glue. More often book wreckers appear when books on shelfs cost too densely or them not often remove with polok and also when the premise is seldom cleaned.

Are especially dangerous lichinki bugs-grinders and house ask. They develop in books close kryshek reliure, on fields of the book block, nearby koreshka. Upon termination of a cycle of development lichinka gnaws through an exhaust outlet in a paper and covers of reliure, creating channels.

Dust — the main enemy of the book. It gathers in those places where volumes cost leaky or leave koreshkami the general of some books. The air stream with motes available always in it and these places changes direction the movement and forms small whirlwinds. Force of inertia throws out from it separate motes which settle on koreshkah and obrezah books.

Therefore it is quite natural, that the books which have been not protected by jackets or cardboard cases, with not painted over obrezami will suffer most from it. The household dust, besides inconveniences in the aesthetic and hygienic attitude, is a source of defeat of books disputes of fungi and a mould which ability to live becomes more active at presence of a moisture.

And at last, about a stamping by means of press. In amateur conditions for this purpose it is most suitable lever press on which it is possible to create pressure about 60 kg/sm2 (fig. 22). As a working element on such to press the copper die in the sizes 25 h 25 h 16 mm (its working surfaces sides 25х х16 mm are) is used nagretaja up to 100 °C. For reduction of traces of pressure of an edge of a die it is necessary to round off slightly. Nagretaja in boiling water during 1 mines the die drained by a gauze, quickly is located in the spring capture strengthened on the lever, and nestles on a binding foil with in advance executed figure or an inscription to a binding material on 3–5 with. The print in the size thus can be received For one reception 16 h 25 mm.

For reception of the gold or silver stamping which are carried out in printing houses on pozolochenyh pressah with heating, in amateur conditions it is possible to recommend first of all besshtampovyj a way of " the hot letter » with use of waste of a binding foil. However, not everywhere it is possible to get such foil, but it is possible to make its similarity the hands.

However the most effective way of removal of traces from ink on pages of books is given with such technology. First the spot is processed by the concentrated solution margantsovokislogo kalija (permanganate kalija), prepared directly ahead of the use. Then, as soon as the paper processed by it pobureet, put on this place of 5-10 %-иый a water solution shchavelevoj acids which can be replaced by solutions of citric or acetic acids of the same concentration or 10 %-нымраствором hydrosulphite of sodium. For reception of good results operation should be repeated repeatedly.

And now some words about a dry-cleaner of the book.

In a note of the century prescription published in the newspaper "Week", the interesting fact was resulted: « Under the certificate of ancient historians, monks should repent, as in a heavy sin if they dropped the book or left on it even the smallest spot ».

The dirt is various, and we plainly do not know, where it have picked up. And at deducing spots it is important to define the nature and structure of spots first of all. Certainly, it is better than spots to not put, but if such happens, remember, that chronic spots and those which nature is not established, completely to deduce very difficultly, and sometimes and it is impossible.

And if speech has gone about technics of pasting, we shall stop нa structures and a compounding of the glues applied in binding business.

As most successful of ready glues consider synthetic glues IIВА (or PVA—) and kmts-¡. Glue PVA (polivinilatsetattsaja emulsija) — the best. On sale it happens in the most various packaging: bottles, tubas, jars. Glue possesses all qualities necessary at work with a paper. Speed of drying (shvatyvanie glue) — one of its main advantages before other glues. At drying it turns to the transparent film invisible neither on a paper white or color, nor on binding materials. Glue has no unpleasant smell, is hygienic, nontoxical and is easily washed off from hands.

Manufacturing of the book comes to the end with an insert of the block in reliure. First of all be convinced, that the cover of reliure corresponds to the sizes of the block. With this purpose the block put in reliure and examine the book: from different directions the block edgings kryshek should support equally its limits, and koreshok — densely to adjoin to koreshkovoj parts of the block.

After primerki a cover put on a soft laying a face sheet downwards and kostochkoj give otstavu the rounded off form. The same operation can be executed, bending koreshok on an edge a cover of a table.

The book — as an alive organism. It is born, lives, can be ill, grow old and even to be lost. To prolong a life of the book, to enable to take pleasure in her not to one generation of readers, to return to it a youth and a life — a problem of the present friends to the book. Therefore everyone binding the book should be a little and the restorer. It doesn't matter, if you do not know all receptions of restoration and reliure of books, it is enough to own at the beginning the alphabet of this business, and skill and skill will come in due course. A unique wish all: be only extremely close and accurate, remember the main precept of the doctor — « do not do much harm! ».
