Subiect: The paper proposes to present techniques and used materials for making the scientific copies of some iron, pottery, stone and bone artefacts. These pieces were found during an archaeological research, during a rescue excavation of a zone with investment purposes. For the negatives, STOMAFLEX was used, the iron artefact replicas were made of DURACOL, chromatically integrated in nuances very close to the originals. For pottery, bone and stone replicas plaster was used, modelling chromatically integrated in nuances very close to the originals. The obtained pieces are the object of an exhibition that will be organized with a permanent character, inside the headquarters of S.C. Michelin Romsteel Cord S.A., in Zalău, Sălaj County.
