Abstract
The paper aims to conduct a novel investigation of some ceramic samples that were taken from Hunedoara's Corvins' Castle (Romania). Some nuclear analytical techniques, such as WDXRF, XRD, neutron diffraction, and neutron tomography, will be used in the investigations. These techniques will be correlated with data from FTIR and Raman spectra. There were experimental data on the mineral and chemical composition that were gathered from the object's surface. Neutron tomography was used to examine the spatial distribution of the phases, while X-ray and neutron diffraction aid in determining the phase composition of the samples under study. The composition of the ceramic samples was identified by the results as follows: quartz, hematite, feldspar, and calcite. Zirconia and titanium dioxide were found in the green pigments. The application of non-destructive techniques that have a high penetration rate into bulk objects seems appropriate in this instance.
