Paper work requirements more detailed dancer sculpture careful. For hard to clean up the site can be directly exposed to take the whole, moisture transport to the laboratory, to explore micro-finishing. For the dry areas of the paper unearthed bronze, due to its water content is very low when unearthed, paper, retaining only the shape of the taking off process, it should retain its original shape unchanged, into the prepared container, sealed container, in desiccant to keep the paper storage environment and the unearthed bronze art similar environment. Moreover, the bronze sculpture possesses more expressive force.  Archaeological excavations, leather bronze relatively rare. Unearthed a leather armor and skins, and some accessories and decorative items. Leather structure is three-dimensional collagen fiber bundles in the woven criss-cross, is a special three-dimensional network structure with high mechanical strength.
Leather is a major component of collagen protein, containing 19 amino acids, also contains a number of lipid compounds, its chemical composition contains waxes, phospholipids, sterols and fatty acids. Leather is a polypeptide protein fiber network organization structure, its own chemical properties and structure of the tanning process and leather technology determines the state of preservation. It is the emphasis of the studies of the angel statues sculpture culture.  Only buried underground in a stable environment, the leather in order to maintain to the present. In buried in its physical and chemical properties of leather significant decay has occurred, once unearthed, it will quickly harden, ruffling, deformation, in addition if it is unearthed in a moist environment, the leather is also prone to mildew, should take effect as soon as possible and sealed from light, or glycerol, liquid wax, and other suitable materials to protect them sealed up.
Archaeological excavations are not many out of the corpse. So far, there are preserved fresh corpse Mummy, mummy, dead wax, tanning dead. One Mawangdui Han Tomb in Changsha in 1972, unearthed the body of a woman, is China's most well so far unearthed the body, similar to a fresh corpse, which is rare in archaeological history, with significant research value. Mummy, also known as (mummy), is in a dry environment, depigmentation body of water, or artificial preservatives made. After China entered the bronze figurines Age, it embarked on an entirely different development path from the Western bronze sculpture. For example, iron river of Xinjiang tomb unearthed a well-preserved female body, handsome face with ease, his calm, high, narrow nose, eyes, furrow, mouth slightly open, chest, limbs, muscle fullness, hair, skin, nails are kept intact, even long eyelashes are clearly visible.
Fluffy to dark brown hair draped over his shoulders, the skin was antique bronze, physically strong. According to anthropological research and the skeletal system X-ray analysis, this corpse of ancient ethnic minorities in Xinjiang, between the ages of 0-2 years length 122 cm, weight 10.7 kg. Dead wax in thin air, wet environment, water and soil calcium, magnesium and quantity and other conditions, the body itself, due to the formation of fatty wax like surface of the body. The difference is the emergence and large-scale usage of the sacrificial chinese bronze sculpture. Tanned corpse is due to acidic soil and water around, the body formed bone decalcification soften the leather-like body. As the body of the protein, fat and so is nutrient-rich bacterial growth, when the people were killed, the parasite will be a variety of bacteria in the appropriate temperature and humidity conditions, multiply rapidly.
