Dr. Elissavet Dotsika Dr Elissavet Dotsika received the B.Sc. degree in Geology Science and the M.Sc. and Ph.D degrees from the University of Paris XI (ORSAY), Lab. of Hydrology and Isotope Geochemistry, in 1988 and 1991 respectively. She was the founder of the Stable Isotope Unit (SIU)- the only Isotope Laboratory in Greece with an international collaboration network. SIU is well equipped with state-of-the-art infrastructure for the analysis of stable isotopes in bio-geo and natural materials.
Dr Dotsika is currently Director of Research at the Institute of Nanoscience and Nanotechnology (INN), leader of the ‘Material and Environmental Isotope Geochemistry’ (MEIG) research group, of NCSR Demokritos. She coordinates the ‘Culture Heritage’ program of the Institute, and is the head of ‘Stable Isotope laboratory’ (SIU). Since 2009 to present she is Associate member of ‘Consiglio Nazionale delle Ricerche ‘(C.N.R.), Institute of Geosciences and Earth Resources, Pisa in Italy.
Dr Dotsika was National Representative for four Actions COST. She is the principal investigator for many research projects with focus on Isotope Geochemistry. She participated in the EC project E.U., and in bilateral projects. She was also leader in International Atomic Energy Agency, in C.N.R. and in General Secretariat for Research and Technology (GSRT) projects, aiming to enhance Isotope facilities and know-how in Isotope Geochemistry focusing on material science, environmental evolution and cultural heritage. She has several International collaborations in particular with partners from the EU countries. She has (co)authored more than 150 scientific publications (including 60 in referred scientific journals, 7 book chapters and 83 papers in international (70) and National (13) conference proceedings). She has also trained 9 PhD, 8 Master students and numerous students towards their Diploma Thesis. She is reviewer in 21 international Scientific Journals.
From the 7th century B.C. the composition of glass changed radically and the natron-based glass, became in Mediterranean regions. It is characterized by the use of evaporitic natron mineral as a source of sodic flux and presents low levels of magnesia and potash (LMLK glass). It is known that after the decline of the Mesopotamian and Egyptian glassmaking traditions, during the second millennium B.C. until the Islamic period, plant ash glass became uncommon in the Mediterranean context. The question about the geographic distribution of the primary and secondary workshops is still unclear, as well as the provenance of the raw material for glassmaking. To address these issues we present here the first set of stable isotope (18O) results for samples from 8th to 4th century BC glass from Makrygiallos area together with new isotopic results for northern Greece natron (Pikrolimni) and sand samples.
