Secondly, it should be mounted in time. If it is damaged or the image quality is damaged, it should be repaired and mounted by professional craftsmen. If the painting is really expensive, the better the mounting material, the better.
And to keep the painting dry, it is best to keep the painting environment constant.
First of all, pest control is the primary problem. Generally speaking, insect repellent is used for painting and calligraphy to prevent insects. Health balls, mothballs, p-dichlorobenzene and other commonly used drugs are white solids, which are volatile. And Mr. Guo of Ann likes to use peppers.
Wrap it in an ancient painting brocade box to prevent insects.
Second, calligraphy and painting, like other objects, have their own most suitable temperature and humidity requirements. Generally speaking, the temperature of 15℃- 18℃ and the relative humidity of 55%-65% are most conducive to the preservation of calligraphy and painting. Too high temperature will cause discoloration, fading, warping, deformation and even fragility of calligraphy and painting; Too high humidity is easy to breed diseases such as mold, which is a great threat to organic matter such as calligraphy and painting. In particular, oil paintings should not be hung near heating equipment such as stoves, which may easily lead to the melting of oil painting pigments.
Third, shelves, cabinets, boxes, etc. The place where calligraphy and painting are placed should not be close to the ground or wall. They should be placed at an appropriate height, preferably at a certain distance from the wall. Also check whether the wall on the back of the painting hanging on the wall is wet. In addition, it is best not to irradiate the light for too long.
Fourth, under normal circumstances, ancient paintings should not be hung for too long. It can be exhibited twice a year 1 to 2 months each time. When rolling calligraphy and painting, loosen it first and then tighten it, then loosen it and roll it up, and then slowly turn the shaft head to tighten the picture scroll. Then tie it with picture tape, and the weight must be moderate. Too loose makes the picture loose and easy to fold. Too tight will leave a hard mark in the middle of the picture scroll, which will affect the overall beauty of the picture.
If it is a professional auction house, you should buy a cultural relic showcase. Putting your own paintings in a cultural relic showcase with constant temperature and humidity can avoid the invasion of temperature, humidity and sunlight on paintings, lacquerware and silk that are difficult to preserve.
