Fossil wood samples dated by the CIRAM laboratory
The CIRAM has dated two fossil woods whose exceptional preservation is explained in particular by their burial in a humid, oxygen-poor environment.

CIRAM uses scientific imaging to reveal the hidden face of artworks, without alteration or sampling. It allows for:
Thanks to this expertise, CIRAM offers a precise visual diagnosis, valuable for restaurateurs, conservators, and experts.

In the archaeological context, scientific imaging opens up new perspectives:
CIRAM accompanies archaeologists in the field and in the laboratory for a complete, respectful, and scientific reading of heritage.
Contact our teamsOptical imaging allows for the examination of surface and underlying layers of artworks without contact or sampling. CIRAM uses:
These examinations are valuable for understanding the creative process, authenticating a work, or guiding a restoration. Non-destructive and deployable on-site or in the laboratory, these techniques offer conservators and experts a precise and reliable reading of pictorial or manuscript works.

These technologies are used alone or in conjunction with other methods such as thermoluminescence dating, and are adapted to the specific needs of art, archaeology, and conservation professionals.
For nearly 20 years, CIRAM has been putting its interdisciplinary expertise at the service of heritage professionals: museums, archaeologists, restorers, auction houses, collectors.
Our equipment – X-ray radiography, CT scan, UV fluorescence, infrared reflectography, raking light – is deployed in the laboratory or on-site, depending on the object's constraints and the project's objectives.
Each mission is conducted with absolute scientific rigor, and results in an actionable report for heritage professionals and the art market.
It can detect restorations, identify hidden signatures, reveal preparatory drawings and analyze materials non-intrusively.
It makes it possible to study artifacts without altering them, and to carry out virtual excavations on sealed or fragile objects.
Yes, our portable equipment enables us to intervene directly in museums, on archaeological sites or at a collector's home.
This depends on the analysis required, but we are committed to delivering results as quickly as possible.
