LUNG-CHUAN YAO and KO YAO. It will be convenient to class together these two most important types of Chinese porcelain. At the present day these names are applied in China to some comparatively common varieties of porcelain, not necessarily of any great age. But more strictly Lung-chuan yao is the term used by the Chinese for the heavy celadon pieces, whether dating from Sung or from Ming times, which were the first kinds of porcelain to become a regular article of export; while the word Ko yao is used as a general name for many kinds of crackle ware, which may vary in colour from white to a full celadon. In a more restricted sense it includes only the early pieces with a greyish white glaze and well-marked crackles. LUNG-CHUAN WARE was made during Sung times at a town of that name in the province of Chekiang, situated about halfway between the Poyang lake and the coast. In Ming times the kilns were removed to the adjacent provincial capital, Chu-chou Fu, nearer to the coast. This was probably the ware that Marco Polo saw when passing through the town of Tingui. It was largely exported from the ports of Zaitun and Kinsay. It will, however, be better to defer the discussion of this thorny question to a later chapter, when we shall have something to say about the way in which the knowledge of Chinese porcelain was spread through the Mohammedan and Christian west. It will be enough for the present to mention that the Lung-chuan ware was the original type and always remained one of the principal sources of the Martabani celadon so prized in early Saracen times. As this is the first time that we come across celadon ware,[31] we may mention that we use the term in the older and narrower sense for a greyish sea-green colour tending at times to blue. The name is, however, sometimes made to cover nearly the whole range of monochrome glazes. It is the _Ching-tsu_[32] of the Chinese and the _Sei-ji_ of the Japanese. The true Lung-chuan celadon of Sung times was, however, of a more pronounced grass-green colour. But we are concerned rather with the later celadon made at Chu-chou Fu during the Ming period. For it is to this time that we must refer most of the heavy dishes and bowls, often fluted or moulded in low relief with a floral design of peony or lotus flowers, or again with plaited patterns surrounding a fish or dragon [Illustration: _PLATE III._ 1--CHINESE, CELADON WARE 2--CHINESE, CELADON WARE]
