Kn. Yu et Jm. Miao, Retrospective study of the feasibility of using EDXRF for the attribution of blue and white porcelains, X-RAY SPECT, 28(1), 1999, pp. 19-23
Two important aspects of the feasibility of using EDXRF for the attribution
of porcelains were solved. First, elements such as Mn and Co were defined,
and identified as elements characteristic of the colorant, so ratios betwe
en their concentrations (e.g. Mn/Co) are meaningful parameters. Second, it
was found that elements characteristic of the colorant diffuse from the col
orant into the glaze layer during high-temperature firing. Therefore, the g
laze layer also contains information on the colorant which can be revealed
by EDXRF, It was also shown that the half-value thicknesses calculated for
Rb, Sr, Y and Zr coming from the body of the porcelain can contribute to th
e EDXRF results. Therefore, the EDXRF results contain information from the
glaze, colorant and the body. This confirms the feasibility of the attribut
ion of porcelains using EDXRF, which is based on the variation of the mater
ials used for the glaze, colorant and body in different periods and localit
ies. Copyright (C) 1998 John Wiley & Sons, Ltd.
