The excavation of the Von Cang Dor site has yielded the first collection of glazed bricks and tiles that were archaeologically found in Tibet,providing important materials for studying their chemical compositions and technological characteristics which are still poorly understood.In order to enhance the understanding of the pottery craftsmanship and technological origins during the Tubo period,this study employed scientific methods to examine ten pieces of glazed bricks and tiles unearthed from the site.The results indicate that the raw material for making glazed tiles was procured from the sources near the site,which is high-calcium and high-iron fusible clay from the Qushui area.The tile making technology from the Central Plains was also been employed.The glaze system comes from complex sources,with blue and green glazes,also known as turquoise glazes,originated from the Islamic alkali glaze system in West Asia.White glaze belongs to the sodium-aluminum system,and has significant differences in composition compared to the white glazed ceramics from the same period in the Central Plains region.The developed transportation routes during the Tibetan Kingdom period allowed for the integration of pottery making techniques from neighboring regions,promoting the rapid prosperity of the Tubo's technology for making architectural glazed tiles and bricks.
