| Abstract: | A quantitative evaluation method was elaborated to determine the gold, silver and copper concentration of high gold content objects in a non-destructive way. The spectrum evaluation method rules out the effect of the differences in size, shape and surface. A long measuring time allows qualitative analysis of the trace elements: Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Cd, In and Zn. Using this method, about 200 golden coins and jewellery from the 10th-15th century Hungary and Byzantium were analyzed. Some of the results are presented here. |
