After a very long period of time, the ancient calligraphy and painting will inevitably be a little damaged or dirty, etc., Jinan purchased calligraphy and painting today to share with you some methods to repair the damage of celebrity calligraphy and painting, I hope to have some help for you.

1、去污：画心因烟熏尘染，质地变黄变黑，如画面颜色稳固，可将画心放入清水内浸泡，隔时换水,即可明净。污迹较重，可用热水浸泡，或缓缓浇淋开水。画面颜色受潮返铅的，可用双氧水涂抹。画心生霉，有黑有红,黑霉易涂，红霉可用高锰酸钾溶液涂在霉处，稍时再涂双氧水和淡草酸水，如霉不严重，一次即可除掉。用药物去污后，务必用清水冲淋画心，免蚀纸绢。

1. Decontamination: the heart of the painting is dyed by smoke and dust, and the texture turns yellow and black. If the color of the picture is stable, you can immerse the painting heart in clear water and change the water from time to time to make it clear. Heavy stains can be soaked in hot water or slowly poured with boiling water. If the color of the picture is affected by damp and lead, it can be eliminated by smearing with hydrogen peroxide. If the mold is not serious, it can be removed once. After decontamination with drugs, be sure to wash the painting heart with clear water and avoid etching the paper silk.

2、揭旧：揭前在画心正面用排笔蘸清水或温水刷湿，并覆盖新纸一张，反置案上待揭。古旧字画多有断裂，如在揭心之前，不附加垫纸，揭托之后，不易起案。画心局部颜色不稳定的应稍施淡胶矾水，干后再行闷水。有些残破糟朽的画心，当日揭不完时，应在已揭过的部位，均匀地放置些湿纸团，然后覆盖一层塑料薄膜，以防画心干裂错位。揭画心上的旧纸，一般应根据字画的薄厚、残状、颜色以及质地的具体情况制定揭旧方案。

2. Uncovering the old: before uncovering, wet the front of the center of the painting with a pen dipped in clear water or warm water, and cover it with a piece of new paper, and put it on the case to be uncovered. Ancient calligraphy and painting are often broken, such as before uncovering the heart, without additional pad paper, after uncovering, it is not easy to start a case. If the local color of the painting center is not stable, it should be applied with light glue alum water, and then the line of stuffy water after drying. When the damaged and decadent painting heart can not be uncovered on the same day, some wet paper should be evenly placed on the uncovered part, and then covered with a layer of plastic film to prevent the painting center from cracking and dislocation. When uncovering the old paper on the heart of the painting, the scheme of uncovering the old paper should be made according to the thickness, residual shape, color and texture of the calligraphy and painting.

3、托补：已揭好的画心，如完整可调兑稀糊，托一层比命纸命绢稍浅的旧色纸。如有残缺，可用手将画心残处边际揉出薄口，选好补纸,端正纹理补上，并在补口边际搓出薄边，使接缝处厚度适宜。补缀残缺的绢本字画，一种方法是揭毕待干，用刀将残处刮成薄口，上糊补绢，浆口干后再修刮补绢边际，使补口相合。另一种方法是托上一层与原命绢质地、丝纹相近的薄绢。正面如有残缺，可用素纸补在托绢的背面，使画心薄厚统一，干后再用刀修磨画面残缺处的边际。托旧绢画心时，要用干纸吸去正面的溢糊，以免留有浆迹,影响古旧作品的"褒光"。

3. Patching: the uncovering heart of a painting, if complete and adjustable, can be mixed with a layer of old colored paper slightly lighter than the life paper. If there is any defect, you can knead the edge of the residual part of the painting center out of the thin mouth by hand, select the mending paper, correct the texture, and rub the thin edge at the edge of the joint to make the thickness of the joint appropriate. One way to mend the incomplete silk calligraphy and painting is to scrape the remnant into a thin mouth with a knife, paste and mend the silk, and then repair and scrape the edge of the mending silk after the pulp mouth is dry, so as to make the mending match. Another method is to support a layer of thin silk with similar texture and silk grain to the original silk. If there is any defect in the front, plain paper can be used to fill the back of the supporting silk to make the painting center thin and thick. After drying, use a knife to polish the edge of the incomplete part of the picture. When holding the heart of the old silk painting, dry paper should be used to absorb the excess paste on the front, so as to avoid leaving traces of pulp and affecting the "commendatory light" of the ancient works.

4、全色：字画经揭托，待干后，务使补纸补绢的矾性适度。否则矾轻则透色，矾重则滞笔。全色时，应将颜色调兑得浅些，复次全就，使颜色渗进纸纹纤维，取得画面色调统一的效果。画心有缺笔的，补全时需先审视画心气韵及用笔特点，然后轻勾轮廓，调兑颜色，进而全之，力求使补全的一笔一点、一墨一皴均与原画浑然一体。对于一些具有重要学术研究价值的经卷、书籍、契证等文物，经过洗污补托，如有残缺，不必求其复原，只把残缺处的色调全补得与通幅基本一致即可。

4. Panchromatic: calligraphy and painting by Jietuo, after drying, make sure that the alum of paper and silk is moderate. Otherwise, alum light color, alum heavy stagnation pen. In panchromatic process, the color should be blended shallowly and fully again to make the color infiltrate into the paper grain fiber, so as to achieve the unified effect of picture tone. If there is a lack of strokes in the painting heart, it is necessary to first examine the charm of the heart of the painting and the characteristics of the brush, and then light the outline, adjust the color, and then complete it, so as to make the completion of a little, a ink and a texturing are integrated with the original painting. For some cultural relics with important academic research value, such as scriptures, books, deeds and certificates, if there is any defect, it is not necessary to restore them, but to make up the color of the incomplete part basically consistent with the general width.
