Problem description:

I bought some bamboo root carvings these two days. I heard in Tianjin that things like wood are not easy to preserve. How should bamboo root carving be preserved?

Analysis:

If you want to maintain bamboo root carving, please refer to the following methods:

The attachments of bamboo carvings handed down from ancient times have taken root and sprouted, so it needs to be cleaned with proper amount of soapy water, which will hurt the old patina, and the old patina with Bordeaux is not only a witness of historical years, but also feels good and beautiful. The washed bamboo carving is still dry with walnut oil. However, after cleaning, the pen container coated with walnut oil is not easy to get worms. Whether it needs washing depends on the specific carving. For those that must be cleaned, try not to damage the bamboo skin when cleaning.

Stir-fry special protective oil with raw walnuts with shells, not walnuts. Walnut fried with shell has less oil deposition and contains a certain amount of water, which is not dry and does not hurt things. The fried oil of cooked walnut kernel is very dry, and bamboo carving is easy to crack after drying. Because most of the owners of old bamboo carvings have been maintained for generations, when oiling, you only need to gently touch a little with your index finger, and take the oil on the skin surface of your fingertips as the degree, put the oil on the palm of your other hand, rub it evenly with both hands, and then play with the carving with both hands, and you can achieve the purpose of maintenance. There is not much oil, and it is easy to regain moisture when there is more.

In addition, it is forbidden to scrape the attachments on the bamboo carving with various tools, which will affect the original appearance and appearance of the carving. Don't apply any paint or chemical pigments. Although there is a saying about painting in professional books, we should consider its advantages and disadvantages. The old carving itself has maintained grease and sweat for many years, and it is difficult to dry after painting. Although the carving can be guaranteed not to crack, it will not form the aesthetic feeling of bamboo due to natural discoloration.

Conditional collectors can put the collection in a glass cover and keep it sealed. If there is no constant temperature measure, in order to avoid the high temperature produced by the glass from cracking the carving, a paper ball can be thrown in the carving at ordinary times, which has the function of regulating the dryness and wetness. You can also put one or two bristle brushes with wooden handles, with hairs facing upwards, which can radiate the heat in carving. The wooden handle has the function of moisture absorption and heat dissipation, so it must be taken out even in rainy days. On the other hand, due to long-term sealing, once exposed to air or wind, it is easy to cause cracking. Preserved in this way, you can keep the temperature constant and hit it several times regularly.

It is best to make a special wooden inner lattice cabinet for easy storage. When the temperature of the special storage cabinet is 20℃ to 35℃ and the relative humidity is 35% to 40%, porcelain or other articles are placed at the lower part, and bamboo carvings are placed at a distance of 1 m from the ground. If the temperature is too dry and too high, you can put a bowl of water indoors or put some books in the cupboard. If the collector lives upstairs, when it is too dry in summer, he can put half a glass of water on the lattice, but keep a certain distance between the sculpture and the glass, check it frequently, and take it out in time when it is not needed. You can also use the method of putting old newspapers, but newspapers are very resilient and should not be used too much. Moreover, we should always fight and check, especially in the season of concentrated rainfall every year. If you find long hair, remove it with a bristle brush in time.
