“…The paramagnetic species Fe 3+ is heat sensitive and a variation in the value of the g-factor is seen after repeated heating [17,18]. Equation 5 may be used to derive the g-factor of the Fe 3+ EPR spectrum by substituting the value for the magneton of Bohr and the value of the experimental Ho.…”

“…The firing temperature of the archaeological pottery pieces was estimated using the assumption that when the g-factor reaches the temperature at which the ceramic fragment was fired, it suffers a perturbation and its value changes. This variation in the g-factor value is caused by variations in the symmetry of Fe 3+ [18].…”

This article presents the results of applying three archaeometry techniques in archaeological ceramics from the upper river Madeira region in Amazonia. The first consists of the nuclear technique, neutron activation analysis (INAA), to identify the trace elements of the clay sources used in the production of the vessels. The second, non-nuclear X-ray diffraction (XRD), was used to characterise the mineral phases of each clay source. The third technique, electron paramagnetic resonance spectroscopy (EPR), estimated burning temperature related to the production stage of the artefacts. This approach made it possible to understand technological choices linked to selecting specific clay sources. The results suggest that different indigenous groups that inhabited the region between 940 and 760 B.P selected three clay sources to produce their vessels.
