CERAMIC MATERIALS - THE USE OF PHYSICOCHE MICAL METHODS FOR THE DETERMINATION OF FIRING TEMPERATURES

Improvement of our understanding of archaeological materials is nowada ys linked to the use of modern methods of analysis. In the case of cer amic materials: different spectroscopic methods have been used and, ho wever, the electron paramagnetic resonance spectroscopy (EPR) is not c ommonly used for such studies. This method is generally easily used an d can provide a lot of information concerning the materials and peculi arly be indicative of the firing temperatures. It was possible to obta in these temperatures for a number of ancient samples, with a fairly g ood precision. The EPR results obtained on archaeological samples have also been correlated to the results obtained from a dilatometric stud y of the same materials.
