| Abstract | It is common to modify valuable, sophisticated equipment, which has been originally acquired for other purposes, in order to adapt it for the needs of additional educational experiments, with greater didactic effectuality. The present project concerns a setup, developed from components of a portable system for X-ray fluorescence spectroscopy (XRF), aiming at: i) the formation of familiar and conventional laboratory exercises, like the verification of Moseley's law, Comp-ton's law and Lambert-Beer's law; ii) the calibration of the XRF with reference materials, aiming on quantitative measurements of the elemental composition of objects of cultural interest. Using the calibrated experimental setup indicative measurements of metal objects are de-monstrated, in order to discuss their spectra and their qualitative and quantitative analysis. The system and the applied experiments are designed as an educational package of laboratory exercises on the one hand for students in physical sciences and on the other hand it is especial-ly adapted for the education of students who will work in the field Cultural Heritage, such as conservation science or archaeological science. The material characterization of ancient artefacts and art objects via analytical equipment is important in many respects, such as in terms of sustainable conservation planning or in terms of investigating ancient technologies. |
