The sites include the Shanglin lake area and Silongkou kiln ruins extending to an area around 231.69 ha, surrounding the water system of the Shanglin Lake and Guyinding Lake, where 116 sites have been discovered so far.

There are abundant remains of porcelain shards accumulated on the ground, buried workshops, kilns and other remains of production facilities, as well as historic settings related to porcelain production including porcelain clay zone, firewood resource zone, slopes where kilns were located, water sources and transport waterways.

Chinese ceramics show a continuous development since pre-dynastic times and are one of the most significant forms of Chinese art and ceramics globally.

1400 BC) through to the fine European and Chinese porcelains of the fifteenth to nineteenth centuries.

The range of materials investigated includes tin-glazed earthenwares, mediaeval terracotta roof tiles, majolica and bone Chinas from which it has been possible to deduce the salient features of the ceramic bodies, glazes and the applied pigments where appropriate [].

Previously, β-wollastonite has been found in a range of sixteenth to nineteenth century European porcelains but this is the first report of its detection in porcelain believed to be from the Ming period.

These same shards exhibited unusual spectral features that were attributed to the resonance enhancement of rare earth elements that resulted from excitation using a near-infrared source.] has produced extensive literature which extends over several thousand years of civilisation from Egyptian faience of the eighteenth dynasty (ca.

The non-destructive analysis of ceramics poses several challenges for spectroscopists because of their composite nature, where the sintered grain and domain sizes range from a few microns to about 500 μ, the presence of crystalline and glassy phases along with unreacted starting components, and the inhomogeneity of the ceramic matrices arising from diverse processing technologies, firing sequences and kiln temperatures.

Where ancient records exist from porcelain factories, the scale of the problem can be assessed; for example, at the Meissen factory in the eighteenth century there were more than five recorded porcelain bodies which were recommended for use at different levels in the firing kilns to account for temperature inhomgeneities [].

Chinese ceramics range from construction materials such as bricks and tiles, to hand-built pottery vessels fired in bonfires or kilns, to the sophisticated Chinese porcelain wares made for the imperial court and for export.

Porcelain is so identified with China that it is still called "china" in everyday English usage.

The earliest Chinese pottery was earthenware, which continued in production for utilitarian uses throughout Chinese history, but was increasingly less used for fine wares.

Stoneware, fired at higher temperatures, and naturally impervious to water, was developed very early and continued to be used for fine pottery in many areas at most periods; the tea bowls in Jian ware and Jizhou ware made during the Song dynasty are examples.

The colossal scale and profuse historical remains of the sites substantiate the invention and lineage of the time-honored celadon making tradition of China.
