Archeological Research of Ancient Porcelain Kilns

In the field of archeological chemistry of Chinese ancient ceramics, there are two difficult problems not solved for many years. The first problem is the location of Ge kiln. And the seeond problem is the existence and location of the Xiuneisi porcelain kiln , an official kiln in Song Dynasty near Hangzhou city. 

Ge kiln was one of the five famous porcelain kilns in Song Dynasty. Although a few porcelain products of Ge kiln have been handed down, with some description records in ancient books, the exact location of Ge kiln is still an open question. Some authors believe that Ge kiln was located near Longquan kiln near the south border of Zhejiang province. 

Recently, the archeologists in Zhejiang province have found a site of ancient porcelain kiln at Laohudong region of Hangzhou city. There were a layer of Song Dynasty and a layer of Yuan Dynasty. And many porcelain chips have been found there. Besides, some porcelain chips have been found near this kiln. The chemical composition of these porcelain chips [87 86] is shown in Table 11.7. 

Class 1 denotes the porcelain body of chips in Song Dynasty layer in Laohudong kiln site, class 2 denotes the porcelain body of chips in Yuan Dynasty layer in Laohudong kiln site and class 3 denotes the porcelain body of chips of Jiaotanxia kiln site. 

By SVM method, a criterion can be found to differentiate the porcelain body of the products of Laohudong official kiln from that of Jiaotanxia kiln at Hangzhou in Song Dynasty
