Terracotta
Thermoluminescence gives an approximate dating of the last
firing of the object.
X-ray radiography permits to
evaluate the structural homogeneity of the piece.
Approximate dating.
Unique method
adapted to terracotta giving this result.
Not representative of
the whole object.
Direct view of the
restoration areas, of eventual falsification
and setting-up.
No material analysis:
can not determine the making-period of
the object.
Jointed use of the methods
- Approximative dating of the material - Homogeneity of the whole

In summary…
The authentication research means the complementarity of the analysis methods:
Constitutive material of the object’s analysis Visualization of its internal structure
CIRAM proposes a wide range of analysis permetting to bring the necessary informations
for a rigourous research authentification.
