The ancient glaze of Western Han Dynasty from Tangpai

Hepu

Guangxi has been investigated by XRD

XRF methods.The XRD results showed that the glaze was real glass with the index of refraction in a range of 1.473-1.479

while the XRF analysis indicated that the contents of SiO2

KZO

CaO

Al2O3

Mgh and Na2O in the glass corresponded to 75.8%-79.0%

10.4%-14.5%

1.3%-2.1%

1.9%-2.7%

0.22%-0.50% and 0.21%-0.87% respectively

belonging to the Si-K vityeous system.The values of 207Pb/206Pb and 208Pb/206Pb in the range of 0.8746-0.8953 and 2.142-2.178 respectively

were close to the distribution of other Chinese early glass

but far from that of the European and Egyptian ones.Therefore

a conclusion can be reached that Si-K glass of Tangpai was made in China and impossible from foreign countries.
