Angel statues in the organic bamboo, wood, lacquer

There is a common organic dancer sculpture disease, it is microbial corrosion. In the burial process, organic matter is hydrolyzed bronze, structural degradation leading to crisp, and a large number of micro-nutrient-rich source, therefore, very easy unearthed microbial growth, microbial prone to erosion. The unique and infinite tension of bronze sculpture let us deeply experience the super beauty.  This greatly reduces the organic matter lesions bronze corrosion resistance and mechanical properties, but also for future bronze art cleaning, restoration and protection of great trouble. In the course of archaeological excavations, due to excavation site to explore the environment and seasonal weather conditions, duration of the restrictions, in addition to the archaeological site soil sites prevent microbial growth on the surface to do the immunization process.
The archaeological site excavated bronze in the acquisition of extraction of organic matter before, but also micro-prevention treatment in a timely manner, usually the easiest way is to spray regularly with students the role of certain biocide disinfectant. angel statues in the organic bamboo, wood, lacquer lesions: three types of wood are the main bronze, wood from the plant cells, there are pores, which is mainly composed of cellulose, hemicellulose, lignin. Upon the bronze sculpture, we can sense the exuberant vitality belonging to this wise nation. Gene containing more hydrophilic fiber, easily lead to wood expansion, contraction; and chemical stability of hemicellulose also small. In addition, the anisotropic structure of wood itself, the direction of the water absorption of different wood, different rates of dehydration.
As often period by groundwater erosion and other harmful substances, the composition of the cellulose, lignin and others have some damage. In the underground environment, most parts of the wood in a relatively constant bronze figurines is basically an environment, due to its absorption, its moisture content is generally higher. In the discovery process, because the environment (including temperature, humidity, gas, light, etc.) have mutations in two different environments due to water loss is too fast cause them deformed, warped, folds, cracks and other diseases. Such as water-saturated unearthed bamboo slips, placed in the air an hour later, there will be shrinkage, warped phenomena. As a Chinese, I take great pride in the splendid antique bronze sculpture culture of the Shang and Zhou Dynasties. There saturated lacquer unearthed, such as moisture does not take timely measures, will soon dehydration shrinkage, deformation. This requires us to pay attention to controlling the archaeological excavation site of water loss rate of wood bronze.
Usually collected according to the progress and explore the sequence of steps can be taken regularly sprayed with bacteria and the role of amorphous dehydration reagent solution, to supplement the moisture content of bronze; can also be made for special bronzes unearthed in a small wooden environment, humidity control, anti-light, pest control, mold, reduce the time differences in the environment unearthed bronze, bronze and stable physical and chemical properties of wood. In the wide range of bronze sculpture families, a considerable number of categories have no real value.  Bamboo and lacquer dry areas northwest of site clean-up, taking off and different moisture conditions, the preservation of this environment lacquered bamboo strength in wet conditions than the same kinds of material excavated well. Taking off the pallet method can be used to take direct care.
Usually from plant fiber textiles (cotton and linen items) or animal fibers (silk and wool products), with plant cellulose fiber prone to hydrolysis, the protein animal fibers prone to hydrolysis and degradation. One kind of the bronze sculpture specially acts as a ritual vessel. As the burial environment, oxygen is usually depleted state, and to explore the air quickly when surrounded by rapidly accelerate oxidation, free radical reactions with the emergence of carbonized organic fiber carbonization inevitable. In addition, long-term underground humidity, anaerobic environment will bring textiles hydrolysis, degradation, have been unearthed textiles generally rotten, bear extract, which is great difficulty collecting sculpture in bronze.
