[Nondestructive analysis of some ancient glass in Jin and Yuan dynasty, by EDXRF probe].

The chemical composition of some glass samples in Jin and Yuan Dynasty were analyzed by EDXRF, to discuss the technological character of these glass samples. The result shows that the chemical composition of these glass samples is very complex. According to the chemical composition, these glass samples include K2-O-CaO-SiO2, Na2O-CaO-SiO2 and K2O-CaO-PbO-SiO2 glass, and a crystal SiO2 sample which was once considered a glass sample. The reason for the color of all blue glass samples is the existence of CuO, but not CoO.

[Nondestructive analysis of a Liuli ring of Warring State Period by EDXRF probe].

A Liuli ring was nondestructively analyzed by EDXRF probe, to discuss the characteristic of chemical composition and the producing place of this Liuli ring. The result reveals that the chemical composition of this Liuli ring belongs to PbO-BaO-SiO2 system, which is similar to Chinese special ancient PbO-BaO-SiO2 glass dating from Chunqiu to East Han state. So, it was concluded that this Liuli ring was used Chinese special technology and formula, and was made in China. But on the appearance, this Liuli ring is not like a mature glass, but a faience or frit which is the compound of glass and crystal substance.

[Preliminary study on the function of potteries of Liangzhu Culture].

Liangzhu Culture is an important late neolithic culture of China, but there are different opinions on the function of some potteries of Liangzhu Culture, for example vat and Ding. In the present paper, for discussing the function of these potteries, the content of Cl, Ca and P of some shard samples of vat and Ding from Liangzhu site were analyzed by using EDXRF line scanning technology. The results show that the content of element Cl in the outside and inside parts of the bottom of vat sample is not different from that of other contemporaneous archaic potteries, and that the distribution of element Cl in the outside part of the bottom of vat sample is the same as that in the inside part of the bottom, so it is concluded that the function of vat from Liangzhu Culture is not related to the production or storage of salt, but with regard to the true function of this pottery more works remain to be done. The analytical results also show that the content of two elements, Ca and P, in the bottom of the other pottery, Ding, is obviously higher than that in vat and other contemporaneous archaic potteries, and that the content of two elements, Ca and P, in the outside part of the bottom of Ding sample is higher than that in the inside part of the bottom. So it is concluded that Ding from Liangzhu Culture is a kind of cooking ware and its main function is meal cooking.
