While the Mongol occupation destroyed much, it also shook China free from the static traditions and techniques of the late Southern Song and made possible many innovations, both in painting and in the decorative arts. The north was not progressive, and the main center of pottery activity shifted permanently to the south. The northern traditions of Jun and Cizhou ware continued through the Jin and Yuan, bolder but coarser than before. New shapes included a heavy, wide-mouthed jar, sometimes with decoration boldly carved through a black or brown slip or painted in two or three colours. These new techniques and the overglaze painting already developed in the Jin dynasty prepared the way for the three- and five-colour wares of the Ming.Auction results:http://www.sothebys.com/content/sothebys/en/auctions/ecatalogue/2014/fine-chinese-ceramics-works-of-art-n09116/lot.212.htmlA 'CIZHOU' BROWN-SLIP PAINTED 'BIRD' BOTTLE VASE (YUHUCHUNPING)YUAN DYNASTYLOT SOLD. 8,750 USD (Hammer Price with Buyer's Premium)http://www.sothebys.com/content/sothebys/en/auctions/ecatalogue/2014/fine-chinese-ceramics-works-of-art-n09116/lot.212.htmlhttp://www.christies.com/lotfinder/lot/a-chinese-chizou-bottle-vase-yuan-4326272-details.aspx?intObjectID=4326272 Condition Archaeological digging find, there is still orange dusty sand inside the vase.
