Natural Condition for the Rise of Ancient Porcelain Kilns of the Tang and Song Dynasties in North China:Outcrops of Coal Strata
In order to investigate the relationship between the emergence of famous ancient porcelain kiln sites and the outcropping of coal-bearing strata in North China during the Tang and Song dynasties.We collected data on 54 famous ancient porcelain kiln sites of the Tang and Song dynasties in North china,and conduct research by coal geology,geography,and archaeology.Spatial analysis shows that these ancient porcelain kiln sites are located within a certain range or even within the outcrop point at the edge of the Carboniferous-Permian coal measures.The overall distribution pattern is"dense in the east and sparse in the west".After millions of years of natural weathering,the exposed coal-bearing kaolinite gradually depolymerized.It was dissolved and leached under the joint action of sulfuric acid,humic acid and carbonic acid,etc,and finally forms gel state kaolin clay with rich water.Weathered porcelain clay is easily accessible to the ancient people after being exposed to the surface.The research shows that the craftsmen in the famous ancient porcelain kiln sites of the Tang and Song Dynasties in North China not only used kaolinite exposed in coal seams,but also used naturally weathered kaolin clay directly.
