Study On Shang And Zhou Dynasties Salt Production Technology

Salt is an indispensable material of human existence, one of the people living in and occupy the important position of state finance. Early research into the history of salt, more to the literature as a starting point and the theoretical basis, the Shang and Zhou dynasties in ancient China, salt formation and development of an important stage, because of the lack of research literature is almost a blank state. Until 90, with the advance of China's infrastructure, some of the Shang and Zhou dynasties are salt salvage excavation sites, the early salt industry became the focus of attention. Many scholars have emerged in the early salt industry on the research results, especially in recent years, some new findings for the in-depth, comprehensive study of the Shang and Zhou dynasties in laying the foundation for salt.In this paper, based on previous studies, the relevant literature and written materials excavated to sort out equipment from the excavated salt, combining with the objective of local geographical conditions, the full absorption of new archaeological discoveries and research results of early salt production a comprehensive analysis of research, science and technology from the perspective of the history of Shang and Zhou dynasties salt production technology process, trying to recover some important salt-producing area was salt production conditions. Text is divided into five parts, including the early salt Dynasty, eastern Chongqing well salt, sea salt northern Shandong, east lake salt and soil salt of Yin, the other, in the conclusion, summarizes the common features of salt and several appliances production salt area of production technology and their connection.Articles that salt is an important factor in early human cohesion. From the Yellow River and Yangtze River in China two cradles of human civilization remains of early human resources and the distribution of brine in the relationship, not difficult to see the areas of human activity is often the gathering of salt resources are more abundant areas. Brine through the control and possession of resources, and then produce the original settlement, the formation of regional economic and cultural center, which is a large demand for salt, the fact that humans are closely related.The Shang and Zhou dynasties of human resources development and utilization of salt is also very limited to production technology, the regional differences in the geographical regions of the salt production technology is different. Hedong Salt Lake is a show on the surface of the natural inland salt lake, Shang and Zhou dynasties fishing salt method set workers poured mining development and reclamation plot drying method; East Chongqing is China's major producing areas of mineral salt, the use of sharp end Cup, won at the end and a small boat-shaped pottery pottery cup salt by boiling and sun rule of law; helmet-type device is the region's major salt Lubei tools, production technology, the Lubei Hedong Salt Lake region and in the same period and in east well salt than the even more diverse. This decision by the unique geographical location:North Shandong area close to the sea salt production, is located above the beach, there are a large number of shallow underground brine resources in a variety of salt that can make direct use of sea sand at the beach to take halogen boiling salt, boiling can also use the underground brine into salt. In the boiling method, but also divided into direct fire boiling and simmer temperature every network in two ways.Because of the large population, the capital of the Shang dynasty has the heavy demand for salt. With the underdeveloped conditions of production and transportation, it's very hard to supply the demand by only importing from outside the capital. During Shang dynasty, there was some alkali soil in the north of Henan province, though the ecological environment there was better and the weather there was warmer and more humid than today. Besides importing salt from Shandong, Shanxi and Sichuan areas, ordinary people may use local materials to make salt for surviving.
