X-ray Fluorescence spectrometry (XRF) is one of the most popular methods used in stud-
ies of historic/cultural heritage objects to obtain information about their main elemental
composition. Not only its time-saving, but completely non-invasive and non-destructive
way of performing measurements can undoubtedly be assumed as major advantages of
this instrumental method. The article describes an example of application of portable
XRF (p-XRF) system during the analysis of altarpiece dated to approx. 1480, originated
from the parish church of St. Elizabeth in Wroclaw. The object, one of the most impor-
tant and most impressive Silesian altars created in the fifteenth century, is now exhibited
in the National Museum in Warsaw and was subjected to XRF investigations directly in
the exhibition room of the museum. The obtained results allowed identification of white
lead/2PbCO3·Pb(OH)2; azurite/Cu3(CO3)2(OH)2; cinnabar/HgS; lead- tin yellow/PbSnO4;
ormolu lead(Au+Cu+Sn+Pb); gold leaf/Au and silver/Ag presence in the layers of poly-
chrome. Only few samples were proposed to be taken for the further studies of stratigra-
phy and more detailed micro-chemical investigations.
