| Abstract: | The multi-analytical approach, including X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy with X-ray (SEM-EDX), was applied to terracotta figurines, mural plaster, and local clay sources coming from two elite burials in Mongolia—Shoroon Bumbagar I and Shoroon Bumbagar II—dated to the second half of the VII century AD. The aims of this study were: (1) by comparing the major composition of body samples with those of the ancient Tang sancai kilns to identify the origin of raw materials; and (2) to track changes in the manufacturing technology. Analysis of CaO, Fe2O3, TiO2, and K2O, which were crucial for distinguishing the provenance of red bodies, confirmed the local production of terracotta figurines. Furthermore, this study helped us attain a deeper understanding of the Tang sancai at both Shoroon Bumbagar sites, geographically located on both banks of the Tuul River yet separated in time by a few decades; it suggests the movement of two groups of artisans using different technologies to make Tang sancai locally by incorporating local tastes and traditions. |
