With the passage of time, the ancient calligraphy and painting will appear natural aging, damage and other phenomena, in order to reproduce the original artistic style, need to repair. Today, I'd like to share with you several ways to repair calligraphy and painting.
The restoration of ancient calligraphy and painting is divided into four steps, which are described one by one below.
1. Decontamination: the texture of the painting center turns yellow and black due to smoke and dust. If the color of the picture is stable, you can soak the painting center in clean water and change the water every other time to make it clear. If the stain is heavy, it can be soaked in hot water or poured slowly with boiling water. If the color of the picture is affected by damp and leads back, it can be eliminated by applying hydrogen peroxide. Black mold is easy to be coated. Red mold can be coated with potassium permanganate solution, and then coated with hydrogen peroxide and light oxalic acid. If the mold is not serious, it can be removed at one time. After decontamination with medicine, be sure to wash the painting heart with clean water, and make sure that the paper and silk are free from corrosion.
2. Uncovering the old: before uncovering, wet the front of the painting center with a paibi dipped in clean water or warm water, and cover it with a new piece of paper, and put it on the reverse side to be uncovering. For example, before uncovering the heart, there is no additional pad paper. After uncovering the support, it is not easy to start a case. If the local color of the painting center is not stable, light glue alum water should be applied slightly, and then the water should be stuffy after drying. When some broken and decadent painting hearts cannot be completely removed on the same day, wet paper balls should be evenly placed on the uncovered parts, and then covered with a layer of plastic film to prevent the painting hearts from cracking and dislocation. To remove the old paper from the heart of a painting, a scheme should be made according to the thickness, shape, color and texture of the painting.
3. Tuobu: the uncovering heart of the painting, such as complete, adjustable blending paste, supporting a layer of old color paper slightly lighter than life paper life silk. If there is any defect, you can use your hand to rub the edge of the heart of the painting out of the thin edge, select the filling paper, correct the texture, and rub the thin edge at the edge of the filling. Make the thickness of the joint suitable. One way to mend the incomplete silk calligraphy and painting is to peel it off and wait for it to dry, scrape it into a thin mouth with a knife, paste the mending silk on it, and then scrape the edge of the mending silk after the pulp mouth is dry to make the mending match. Another method is to put on a layer of thin silk with similar texture and texture to the original silk. If there is any defect on the front, plain paper can be used to fill the back of the supporting silk, so that the thickness of the painting center is uniform. After drying, the edge of the incomplete part of the picture can be polished with a knife. When supporting the old silk painting heart, dry paper should be used to absorb the overflow paste on the front, so as to avoid leaving slurry marks and affecting the "praise light" of ancient works
4. Panchromatic: after the calligraphy and painting are uncoated and dried, make sure that the alum of paper and silk is moderate. Otherwise, the light alum is transparent, and the heavy alum is stagnant. When full-color, should mix the color lighter, repeat all, make the color infiltrate into the paper grain fiber, achieve the effect of unified picture tone. If there is a lack of strokes in the heart of painting, it is necessary to first examine the charm of the heart of painting and the characteristics of the brush, then gently tick the outline, adjust the color, and then complete it, so as to make the completed strokes, ink and texture integrate with the original painting. For some cultural relics with important academic research value, such as scriptures, books, deeds and so on, if they are incomplete after washing, it is not necessary to recover them. Only the color of the incomplete part is basically the same as the width.
