[en] The analysis of archaeological objects requires simultaneously non-destructive, fast, versatile, sensitive and multielemental methods. Romania has a lot of interesting archaeological sites: Greek on the Black Sea coast, Roman in Transylvania and Dobroudja. Byzantine on the Danube border. Our purpose was to help Romanian archaeologists to identify provenance (workshop, technologies, mines) and to explain commercial, military and political aspects. Three methods were used in air 3 MeV protons PIXE ²⁴¹Am source based XRF and FNAA. For in air PIXE, we are used a 3-4 MeV proton beam obtained from the 6.5 MeV Cyclotron nominal regime protons extracted through a 20 μm aluminium foil into the air striking the sample after 8-10 cm. X-ray were detected through reflection using horizontal Si(Li) detector. XRF measurement were done with a spectrometer consisting of a 30mCi²⁴¹Am annular gamma source a Si(Li) detector and a conventional electronic chain. Using both PIXE and XRF methods, we can determine all the elements from potassium to Uranium. Some compositional results on various archaeological ceramics objects from Romanian sites (glaze and painting agents but also clay elemental analyses) are presented. For glasses, chemical differences that occur during preparation of materials will affect the elemental composition and could be used for the identification of technologies and workshops involved. The problems i sto identify colouring agents de colorants, opacifier and fining agents. The XRF and FNAA techniques were used. Some results on medieval and XVIII Century samples founded in South-Eastern Romania are also presented
