Carbon dating art
The combined results of the stylistic, material and scientific investigations will permit the establishing of the compatibility of the painting with presumed elements or its inauthenticity.
Thanks to the laboratory's modern equipment, a painting can be subjected to analysis using infrared reflectography, Wood's light, a stereoscopic microscope, IR spectroscopy and other instrumental techniques.3 e 4 - Microscopic analysis to examine the signs of ageing in the paint layer: the nature of the craquelure (natural or artificial - deep or superficial), the pigments (crystallinity, purity and size), restoration and other factors.
This proves a C-14 test should always be complemented by art historical research.
Obviously, the test dates the age of the used wood and not an object’s date of manufacture.
Carbon-14 (C-14) dating, also called radiocarbon dating, makes it possible to determine how much time has elapsed since an organism’s death – for example, the felling of a tree.
The method is based on the measurement of the amount of carbon-14 remaining in the tested material.
The Museum laboratorys mission is to improve existing scientific methods and elaborate new methods for the ascertainment of the authenticity of art objects.
The laboratorys instruments and know-how for the determining of authenticity are at the disposal of collectors, art experts, restorers, art galleries and museums.
