Taboos for calligraphy and painting collection:
First, avoid pollution, such as oil stains, sweat stains, tea stains and dust, etc., dust often adsorbs acidic substances, mold spores, so that paper acidification, mold.
Second, avoid mildew, especially black, yellow, red, purple and other molds that produce color, the mildew that is produced is extremely difficult to remove.
Third, avoiding insects, squid, tobacco, and other pests, often can ruin the paintings and paintings, and it is terrible.
Fourth, avoid the light, the general light source contains ultraviolet light, the ultraviolet light makes the paper yellow and brittle.
5. Avoid dampness, the paper is easy to absorb moisture, and the paper is prone to mold and rot after water absorption. In addition to damage caused by rot and decay, man-made damage is also one of the main reasons: the destruction of fires, wars, etc., has caused many precious ancient books, ancient calligraphy and paintings, and ancient documents to be lost.
In general, the protection of paper cultural relics is very difficult, and improper collection will damage the appearance of the collection. The ancients collected books with a set of letters, and the paintings used refined paintings. The materials used to make the paintings should be selected to prevent the oily substances in the wood from contaminating the paper. The ancient wood paintings are not only selected (extraordinary eucalyptus), but also multi-layer materials, the outer layer is eucalyptus, the middle is nanmu, the most The inner layer is made of fine silk, and the painting is wrapped with a cloth cover.
The hand is clean and contains contaminants such as oil, sweat, dust and mold. Therefore, it is necessary to take gloves with the paintings and paintings. The distance between the person and the paintings is about 1.5 meters, so that the saliva splashes onto the paintings during the speech. The autumn season is high; the collected paintings can be taken out of the dust and aired to allow the absorbed water to evaporate. Modern furniture materials contain a lot of formaldehyde gas. Formaldehyde is not only toxic to human body, but also damages painting and calligraphy. Therefore, modern cabinets are not suitable for storing precious paper artifacts. In the southern rainy season, the humidity in the air is high and the temperature is high. It is the high season of insects. At this time, special desiccant and insecticide and mildewproof agent should be used to prevent moisture and inhibit the growth of insects.
China's traditional papermaking method is a manual technique. The main processes are: crushing, tanning, evaporation, pulping, paper making and drying of plant raw materials. Traditional papermaking methods do not require chemical additives, while modern papermaking is large-scale. The paper produced by the machine is processed by several kinds of paper chemicals, and the chemical additives left on the paper bring many side effects, which make the paper have poor aging resistance and it is difficult to preserve for a long time. Because of the exquisite materials and the fine production, the ancient paper is basically free of chemical additives, so the above two kinds of hazards are small. The above two kinds of hazards are more prominent in the paper collections of modern collectibles.
