Carbon dating art
Other pigments may be known to have disappeared from the artists’ palette, so their presence permits experts to date artifacts ante quem.
Spectroscopy is also extremely useful to fight forgery.
The lab also offers C: N, %C and %N measurements on collagen extracted from non-cremated bones in addition to δ15N and δ13C at no additional cost for samples sent for radiocarbon dating.
Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7).
Spectroscopy also enables scholars to date objects.
Because some materials were available in particular regions and periods, the retrieval of pigments with a well-known date of invention allows art historians to date artifacts post quem.
Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for carbon-14 measurements.
The lab is based in Miami, Florida, and is the world leader in carbon-14 analyses since 1979.
