Study On Pottery Making Technology Of Wanggou Site In Xingyang

Wanggou site is located in xingyang town,Henan province,Chengguan town Wanggou village about 500 meters south of the sentry land.Its cultural heritage is rich,containing the late early period of Yangshao culture,the late middle period of Yangshao culture,the late late period of Yangshao culture,the early Longshan culture and late Longshan culture.the late Yangshao culture is the most abundant,which is an important site for the study of neolithic culture in Zhengzhou area.In this paper,based on the traditional archaeological research,with the help of scientific and technological detection methods to conduct a comprehensive study of the pottery in Wanggou site,by comparing the changes of pottery making technology in each period,it can also provide some new evidence for the stages of archaeological culture,so as to achieve the effect of mutual verification.Based on the statistical observation and analysis of the raw material molding,trimming,decoration,firing and using marks of the pottery in Wanggou site,the author draws some conclusions.In terms of raw materials,the water absorption rate of the different textures pottery was found to be mainly affected by the pottery.In general,the water absorption of clay is higher than that of sand,the water absorption of black clay after carburizing is the lowest,and the water absorption of sand-enclaminated clam clay is between that of clay and sand.Pottery clay mainly includes common fusible clay,high aluminum refractory clay and high calcium clay,with common fusible clay as the main clay.The rhinoceros and grains in the five stages were mainly grey,brown and black grains.The number of grains mainly white grains increased from the third stage of Wanggou,and the number of grains mainly white grains in the fourth stage was the most.The sand-intercalated ceramics from the first stage to the fourth stage of Wanggou were mainly composed of medium sand,while the coarse sand showed a decreasing trend and the fine sand showed an increasing trend with the evolution of The Times.The sand-intercalated ceramics from the fifth stage of Wanggou were mainly composed of fine sand.With the change of times,the grain size of sand and gravel in several times also shows a trend of gradually refining.The variety of sand and gravel and the change of grain size of sand and gravel also show that the ancients had a certain selectivity in the use of sand and gravel.In terms of pottery technology,the forming technology of the pottery at Wanggou site is mainly the method of making the clay built.The wheel forming method began to appear in the third stage of Wanggou,and the fifth stage of Wanggou is the most common.Trimming methods include beating,scraping,rolling,finishing,slow wheel finishing.In terms of pottery decoration technology,the pottery of the five periods is mainly plain surface and polished pottery.In terms of decorative patterns,the first and second stages of Wanggou site are mainly line and string patterns.From the third phase of Wanggou period,rope and basket patterns become the mainstream patterns.Painted pottery mainly appeared in the late Yangshao period,and gradually declined in the Longshan period.The pottery of the five periods at Wanggou site is mainly grey pottery fired in reductive atmosphere,followed by red pottery fired in oxidation atmosphere,and a small amount of brown and black pottery.Pottery used marks mainly include scale,mostly found on the inner walls of cooking pots and storage vessels,and a small amount of pottery containing pigments,secondary utilization and secondary reform.The regional communication between the Wanggou site and the surroundinging areas on pottery was mainly reflected in the exchange of concepts such as the form of utensils,rather than the exchange of objects.Wanggou site paid pore attention to the development of local pottery technology.
