In order to identify provenance of archaeological artifacts, it is useful to identify their composition. X-ray emission spectroscopy enables fast and simultaneous analysis of all elements in the sample Z. 15. Twenty-eight objects from the Archaeological Museum in Zagreb were analyzed to illustrate the method. Mo-tube was used as an x-ray source for the sample excitation. Matrix effects correction by the method of fundamental parameters was employed. The analysis of 22 objects showed that copper was the main ingredient with concentrations ranging from 43.3% to 97.6%. Twenty-one out of 22 objects contain lead, tin, and iron. Zinc was found in 12 objects. Small concentrations of some other elements were present in few samples (e.g., arsenic 0.2-3.8%, silver 0.4-1.8%, and antimony 0.6-3. 3%). Sorting of the objects can be done according to the percentage of the major elements and/or according to the existence of some minor ingredients (arsenic, silver, antimony, iron and in some cases zinc and lead). The latter could be more significant because these minor components usually indicate that the objects were manufactured when it was still impossible to extract them. X-ray emission spectroscopy as an analytical method gives important results in exploring the origin or age of archaeological objects. -- AATA
