The province of Zhejiang came to be well known during the period of the Southern Song and Yuan dynasty. The province of Zhejiang gained recognition for its production of a particular celadon ceramic. The Southern Song Longquan celadon consisted of a delicately potted body of porcelain which was primarily an uninteresting color of light gray but would be then made to look unique by covering it with a substantial greasy layer of glaze of a particular bluish green tint. The Yuan Longquan celadon wares were larger which had their decoration styles and shapes drawn from the styling of the Middle Eastern ceramic and metal wares. The frayed and ragged coastline of Zhejiang has over three thousand islands situated alongside it. The largest island along the coastline of Zhejiang is the Zhoushan Island and it is the third largest island of the territory of China.
