Use was made of thermal and other techniques to characterise three native asphalt samples. The purpose was to support archaeological
investigations reconstructing their thermal history and composition. The first sample (from a Roman quarry in central Italy)
proved to have 37% impurities, no sign of oxidation or degradation and to have never been heated to above 100°C. The second
sample (from a Roman ship sunk south of France) was pure, but partially oxidised, with a saturated fraction in its structure.
Analyses of the latter sample, obtained from the eye of a Thracian bronze head, revealed that the asphalt had been heated
to over 100°C and then mixed with natural wax.
The hypothesis that the human search for altered states of consciousness through the intake of psychoactive plant sources has very ancient roots is repeatedly confirmed by archeological finds. The present review
Over recent decades the uses of thermoluminescence have been expanding rapidly, as have advances in the equipment available for the determinations of this property shown by many materials. Despite this, the comparable growth of applications in the Earth and Archeological Sciences has been markedly overlooked in the mainstream thermal analysis literature, an omission this review sets out to rectify.

rather exhaustive several techniques should be used. Py-GC/MS was applied to the study of lignin and cellulose in order to investigate decay processes in aged woods [ 3 , 4 ]. CPMAS-NMR technique was applied to archaeological samples from the eleventh
