The quality of translucency which in Europe[315] is regarded as distinctive of porcelain is never emphasised in Chinese descriptions. I can find no mention of it in any of the earlier writings,[316] and the first unmistakable literary evidence of its existence[317] comes from a foreign source. The Arab traveller, Soleyman, who describes his experiences in China in the ninth century, states that "they had a fine clay (_ghādar_) from which bowls were made, and in the transparency of the vessels the light of the water was visible; and they were (made of) fine clay."[318] This statement practically proves the existence of translucent porcelain in the T´ang dynasty, and we confidently await the arrival of specimens from Chinese excavations. Some of the export porcelains of the time have been actually unearthed at Samarra on the Euphrates by Professor Sarre,[319] of the Kaiser Friederik Museum, Berlin, and they include (1) bowls of gummy white porcelain with unglazed gritty base; (2) greenish white ware; (3) yellowish white with small crackle; and (4) a pure white porcelain with relief designs, such as birds and fishes, under the glaze. Other pottery found on that site included mottled ware of typical T´ang type, and a creamy white of the Tz´ŭ Chou type with brown spots.[320] From considerations of form and the general character of the ware, I am inclined to regard three specimens in Plates 44 and 45 as belonging to the T´ang period. Fig. 1 of Plate 44 has a thin ivory white glaze running in gummy drops and clouded with pinkish buff staining outside and with a reddish discoloration within. Fig. 2 of the same Plate is remarkable in many ways. It is so thin as to seem to consist of little else but glaze, and is consequently almost as translucent as glass. The colour of the glaze is pearly white powdered with tiny specks, and the crackle is clearly marked. The base is flat and discloses a dry white body of fine grain. But its most conspicuous feature is the arresting beauty of its outline, which recalls some choice specimen of Græco-Roman glass, and displays a classic feeling frequently observed in T´ang pottery and in the Corean wares which owe so much to T´ang models. Fig. 2, Plate 45, shows the celebrated phœnix ewer belonging to Mr. Eumorfopoulos which has proved so difficult to classify.[321] It is a white porcellanous ware translucent in the thinner parts, and the glaze is of light greenish grey with a tendency to blue in places. The form and ornament show strong analogies with specimens of T´ang pottery. The neck, for instance, may be compared with Fig. 2 of Plate 14; the phœnix head and the foliate mouth with Fig. 1 of Plate 9, and the carved ornament on the body with Fig. 3 of Plate 14.
