Abstract:
Due to its high spatial and elemental resolving power, synchrotron radiation x-ray fluorescence (SRXRF)
imaging is particularly suitable to mapping distributions of elements with low concentration in a small
area. This method has been widely used in chemistry, electronics, and material science [1,2]. Recently, it
has also proved to be an effective and powerful technique to study archaeological samples [3,4].
A glass eye-bead dating to the Warring States Period (475 B.C to 221 B.C.) unearthed from the
Danjiangkou site in Hubei Province, China, was studied by synchrotron radiation x-ray fluorescence
imaging. The eye-bead sample shows a multi-layered structure: the body, the pupil, and the inlaid
colored layers. Figure 1 is the optical micro-image of the sample, which is a patchwork due to the
limitation of the field of view. The distribution information of Pb, Ba, Fe, and Hg elements is obviously
viewed by their SR-XRF images. From Fig. 2, we can see that all five layers contain Ba, Hg is mainly
distributed in the left blue layer and the right light brown layer, while Pb can be found only in the former
and Fe is concentrated in the latter. This suggests that these compounds for the five layers come from
the partly melted materials.
