Abstract

By using the proton induced Xray enission (PIXE) method, the measurements of the oxide compound content have veen carried out for the selected 18 samples of Tang tricolor in Huangye kiln. For ascertaining the classification and origin relation of the samples the principal component analysis method was adopted, and the results indicate that the chemical compositions of Tang tricolor body with diggerent glaze colors are close, which shows that their raw material habitat distribution is quite concentrative. But the prescriptions of diffierent color glaze are different. The content of CoO is more than others in blue glaze; CuO is more than others in green glaze; Fe₂O₃is more than others in brown and yellow glaze; Al₂O₃ is less than others but
SiO₂is more in white glaze, which shows that glaze’s material origin is diffierent, but brown and yellow glaze are close and even the same in chemistry component.
