In order to group specimens of Tang Sancai of unknown provenance to the different kilns according to their chemical compositions, we studied the elemental abundance patterns of Tang Sancai body samples from different tombs, relics and kilns by instrumental neutron activation analysis (INAA). Our results indicated that the development process of Tang Sancai in the Prospering Tang period could be divided into at least two phases, With AD 705 or so as the boundary between them. The results of factor analysis showed that the red-bodied samples were more likely to be produced near Xi'an, whereas the white-bodied Tang Sancai wares dating to before AD 705 were most probably produced at Huanye Kiln (also known as 'Gongxian' Kiln), and the figures were very likely made at an undiscovered kiln near Luoyang or an undiscovered part of Huangye Kiln. Among the white-bodied samples dated from AD 705 to AD 755, both types of figures and wares were mainly produced near Xi'an and Luoyang.
