“…Fig. 3 Location distribution of the consistent wavelength sets Uc1 and Uc2 selected based on the SWSRA method As a further investigation, this study used the PCA method to characterize the differences in spectrum between NIR instruments [24], [25], [26], [27]. The PCA scores of 58 calibration set samples were calculated for the wavelength sets screened by the three instruments (master and target 1, target 2) based on full spectrum and SWSRA methods, and the results are shown in Fig.…”

“…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.…”

Archaeometric Analyses on Precucuteni-Type Pottery From Transylvania (Romania). Case Study: Alba Iulia-Lumea Nouă

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.

As últimas décadas tem presenciado um crescente aumento no uso de métodos físico-químicos de análise de bens culturais. Algumas dessas técnicas tem se mostrado particularmente úteis pelo caráter não invasivo e não destrutivo que apresentam e, dentre elas, a espectroscopia Raman apresenta posição de destaque. Neste artigo, essas características da técnica são detalhadas, bem como são apresentados os fundamentos teóricos do espalhamento inelástico de luz e discutidos alguns aspectos práticos de sua utilização. Finalmente, é apresentado um levantamento detalhado dos grupos de pesquisa da América do Sul, voltados ao estudo de bens culturais, que tem se utilizado dessa ferramenta analítica e em qual tipo de questionamentos vem sendo aplicada. Abstract: The last decades have witnessed an ever growing increase in the usage of physico-chemical methods to investigate cultural heritage problems. Some of these techniques are proving to be particularly useful in such a context, due to their non-invasive and non-destructive nature; among them, Raman spectroscopy occupies a prominent position. In this paper, such characteristics of the technique are detailed and the physical basis of inelastic light scattering are presented, together with some practical aspects of its applications. Finally, it is here offered a detailed survey in the literature on the South American research groups devoted to the investigation of cultural heritage issues who are using Raman spectroscopy, and the type of interrogation carried on.
