SURF 6 15 Figure 1 shows a one-fourth-bronze mirror, its radius being 56.3mm. The mirror is covered with patina and soil, and the decorative pattern on the surface is blurred. X-ray films produced show clearly the distribution of cracks and micro-cracks inside (fig.2, left), and the decorative pattern and writings (Fig. 2, right). The writings and the decorative pattern provide the evidence of dating for the bronze mirror belonging to Han dynasty.

SURF 6 16 The bronze He which was used for drinking wine in ancient time, belonging to the Western Zhou and from the Fufeng country museum. X-ray films reflect the good state of conservation. The radiograph in Fig. 4 (left) shows that the animal handle are cored. At two joints of the handle, there are two bosses which were cast integrally with the vessel. The handle was pre-cast and installed in the outer mold, and then it was jointed together with the body by casting. From the same radiograph the clay spacers (black square block) on the inside core mold of the animal handle can be seen. The radiograph of the lid (fig.4, right) reveals that some clay protrusion on the core mold inside the coiling dragon also exists, which serve the function of as same as the chaplet (spacer) usually being found and used in Chinese ancient bronzes.
