A non-destructive analytical technique used to identify elemental composition in sculpture materials.
X-ray fluorescence, abbreviated XRF, identifies chemical elements by measuring characteristic X-rays emitted after a material is excited by an X-ray source. In sculpture it is used to distinguish alloys, investigate patinas and coatings, compare cast sections, and support conservation decisions.
Etymology
Fluorescence refers to emitted radiation following excitation; XRF abbreviates X-ray fluorescence.
Sculptor Notes
XRF does not tell the entire material story by itself. Results are strongest when combined with visual examination, microscopy, radiography, and fabrication history.
