Natural crystalline materials contain imperfections: impurity ions, stress dislocations, and other phenomena that disturb the regularity of the electric field that holds the atoms in the crystalline lattice together.This leads to local humps and dips in its electric potential.
Ces travaux, précédés d'une étude documentaire, d'une archéologie des élévations et de nouveaux relevés, ont mis en évidence des datations recouvrant le Xe siècle et tendant à montrer que deux ensembles maçonnés se sont succédé.... However, the obtained results do not provide sufficient data to define more detailed intervals (settlement phases) of the studied site.
As already mentioned this trait is characteristic of the vessels dating to the developed eighth century, and in particular, the ninth century.
Fragments of stone extracted from Upper Paleolithic fire places at Combe Saunière, Dordogne (France), have been investigated. Numerous formal and stylistic analogies can be found in pottery assemblages from Sulechów, site 14 and the settlement from the first phase of occupation at Sulechów, site 10.

This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.
