LIBS analysis in Art <strong>and</strong> Archaeology<br />
SELECTED EXAMPLES<br />
Identifying pigments<br />
Pb<br />
Original<br />
LIBS analysis enables discrimination<br />
between original <strong>and</strong> retouched areas<br />
of the painting, based on the different<br />
pigments identified (original: lead<br />
white; retouched: titanium white).<br />
These findings suggest that the<br />
restoration was per<strong>for</strong>med in the 20th<br />
century as titanium white became<br />
commercially available only after 1920.<br />
