“…In the field of cultural heritage analyses, the analytical techniques applied in each study must be selected as a function of the sample nature, as well as the destructive or nondestructive character of the equipment. The most commonly used techniques in the study of the samples from cultural heritage are: scanning electron microscopy coupled with energy dispersive X-ray spectrometry (SEM-EDS) [10][11][12][13][14][15][16][17][18][19], X-ray fluorescence [13,16,17,20], Xray diffraction (XRD) [11][12][13]19], Raman spectroscopy [11-13, 16, 21-23], Fourier transform infrared spectroscopy (FTIR) [10-12, 14-16, 18, 19], X-ray photoelectron spectroscopy (XPS) [24,25], Auger electron spectroscopy [17,25], neutron diffraction [20,26], neutron tomography [13,27], neutron activation analysis (NAA) [20,26], and optical microscopy (OM) [12,13], as nondestructive or minimally invasive techniques. In this study, a combination of few techniques (i.e., OM, SEM-EDS, ATR-FTIR, and Raman spectroscopy) was applied to provide comprehensive information about the studied fragments.…”

The aim of this paper is to find out - for the first time - through archaeometric analysis the provenance of the Precucuteni-type pottery from Alba Iulia-Lumea Nouă settlement and whether it has a local origin or is an imported ceramic. The presence of so-called Precucuteni-type pottery in Transylvanian sites, decorated by motifs using excision techniques, represents one of the most challenging debates related to the understanding of the material culture that belongs to Early Eneolithic human communities in the Intra-Carpathian area. A combination of non-invasive / micro-destructive analytical techniques and statistical methods were applied to provide comprehensive information about the studied fragments. In this respect, ten pottery samples were investigated to establish the elemental and molecular composition, as well as its origin. Overall, the analytical and statistical analyses show us that the local production of pottery is predominant, with a limited presence of imports. In summary, nine ceramic fragments out of all analyzed samples belong to the same group, with a strong correlation between them, confirming that they are locally made, while one sample can be considered as imported from elsewhere or obtained through mixing clay with some existing soils in the area during the pottery production stage.

It is well known that neutron imaging is a powerful nondestructive technique in archaeological studies, especially for visualization of organic contents or low-density parts inside antiques. In Thailand, the neutron imaging system has been developed to perform neutron tomography (NT) for archeological studies since 2015. A compact NT system, which is composed of a CCD camera coupled with a LiF/ZnS fluorescence screen and an in-house developed rotation stage, was used to investigate the internal structure of an object. The experiment was set up at Thai Research Reactor (TRR-1/M1) of Thailand Institute of Nuclear Technology (Public Organization) with the power of 1.2 MWth. The neutron intensity at the radiographic position was about 10 6 n.cm -2 s -1 . In this work, an ancient sample of interest, namely, the 15 th -18 th century terracotta doll was investigated to perform the developed NT system. The resulting 2D neutron image showed a crack at the neck and a small gravel inside the body. Then, the projections were reconstructed by means of the Octopus Imaging software. Even with the compact NT system (L/D: 50), the 3D neutron image of the ancient doll was successfully reconstructed. The image revealed some hidden organic materials coated on the neck of the doll. Moreover, the elemental composition of the terracotta doll was analyzed by using X-ray fluorescence technique. The result could further inform the historical records of the ancient doll.
