The large and important potteries at Po-shan Hsien [Chinese] in the Ch´ing-chou Fu, in Shantung, were represented only by a small exhibit at the Paris Exhibition of 1878, consisting of "a bottle of glazed pottery, three tea jars in red ware, ten specimens of glazed pottery, a brazier in terra cotta, and seven crucibles." Laufer tells us that these potteries date back to Sung times, and have preserved the old traditions of manufacture. The district is also noted for its glass, enamels and glazing materials, but it is situated inland, and not conveniently near any of the treaty ports. In the early days of the European trading companies, pottery, as distinct from porcelain, does not seem to have received much attention from the merchants, and we may fairly assume that most of the earthenwares which reached Europe before the last century hailed from the neighbourhood of Canton or from Yi-hsing and the Shanghai district. But long before the first European vessels reached the coasts of China, Arab and Chinese merchantmen had carried cargoes of pottery and coarse porcelain to the Philippines, the East Indian Archipelago, the Malay Peninsula, Siam, Ceylon, and India. The Arabs had a trading station in Canton in the eighth century, and Chinese junks sailed from Canton and the Fukien ports in the Sung, Yüan, and Ming dynasties. A Chinese account of the sea trade in the twelfth and thirteenth centuries may be read in the work of Chao Ju-kua,[415] and it will be found from this book and from Marco Polo's accounts that Ch´üan-chou Fu on the Fukien coast was a busy centre of foreign trade in the Sung and Yüan periods. Hirth[416] has traced the probable route by which the Lung-ch´üan celadons reached this port for shipment, and doubtless the other wares, including coarse white porcelain, stonewares and pottery, which are found in the Philippines and Borneo (to name only two of many localities) were largely supplied from the Fukien potteries. Many of these wares are of undoubted antiquity, and some of the types are unknown in China to-day. They may have been made solely for export, but in any case their disappearance in China is quite intelligible. For even in the eighth century the merchants were forbidden[417] to export "precious and rare articles," and most of these trade goods are of coarse make and unlikely to be preserved by the Chinese at home. On the other hand, the natives of the Philippines and the Dyaks of Borneo have preserved these old potteries with scrupulous care. The various types of jars have been christened with special names[418] alluding to their form or decoration; they have been credited with supernatural powers; and numerous legends have grown endowing them with life and movement, power of speech, and influences malevolent or benign.
