Abstract

It is revealed that the ancient ceramics found at Ban Muang Bua located in northeastern Thailand, are one of the Thung Kula Ronghai ceramics. They are produced as burial goods for funeral offerings or used as the burial jars and daily-used ceramics. Shreds of these samples are analyzed of the elemental composition and structure using a scanning electron microscope coupling with energy dispersive X-ray fluorescent spectroscopy (SEM-EDS). X-ray tomographic microscopy (SR XTM) based on synchrotron radiation is performed to investigate the three-dimensional (3-D) structure. The elements present as major, minor and trace elements, such as carbon (C), silica (Si), aluminum (Al), phosphorus (P), calcium (Ca), potassium (K), titanium (Ti), iron (Fe), sodium (Na), magnesium (Mg), and Zinc (Zn), were identified to the origin of the samples as the fingerprint. The 3-D tomographic images revealed the internal configuration of these samples. It was shown that the combination of various analytical methods is a powerful tool with which to answer the questions posed by archaeology.
