4. A greyish ware, inlaid with designs of white slip, on the principle of our ‘encaustic tiles’ of the Middle Ages. This is perhaps the only original type that we can connect with Korea, and it would seem that this is the ware alluded to at the end of the quotation we have just given from an old Chinese book. This inlaid ware appears to have been greatly admired by the Japanese, for it was closely imitated in more than one district. The well-known Yatsushiro pottery, first made in the province of Higo in the seventeenth century, is distinctly a copy of this Korean model. Among the specimens at Sèvres brought home by M. de Plancy, there is a tall vase of this type cut down in the neck decorated with flying cranes in white slip. This ware, however, is not a true porcelain; at the best it is a kind of kaolinic stoneware, and the same may be said of most of the old heavy pieces brought back from Korea. There is not much in the way of decorative design to be found on any of the varieties of Korean porcelain or stoneware that we have now described, and we may look in vain among the few ornamental _motifs_ to be found on these wares for any marked divergency from Chinese types. SIAM AND THE INDO-CHINESE PENINSULA. Under the somewhat vague heading of Indo-China we will collect a few notes upon the specimens of porcelain that have been found in the various states into which the great peninsula that stretches south between the China Sea and the Bay of Bengal is divided. In looking through the artistic productions of all these countries, we find one marked characteristic; and that is the way in which Chinese forms and Chinese decorative _motifs_ have pushed their way in and in part replaced the old Buddhist and Brahmanistic styles. As matters now stand, the most important for us of these states is Siam, for here we are at once brought face to face with one of the places of manufacture of the famous heavy celadon ware which in the Middle Ages was carried by Arab and Chinese traders over all the seas of the then known world. We shall have in a later chapter to come back to the question of this trade, and then we shall be able to show that the discussion as to the origin of this _martabani_ ware has been the means, as is indeed often the case in such disputes, of throwing much light on the early history of Chinese porcelain.
