Summary
[edit]DescriptionChemistry; sensitive non-destructive evaluation (NDE) techniques (5940438087).jpg |
Elemental and isotope analysis of the metals in ancient artifacts such as the prutah shown here sometimes can pinpoint the places where the metal was mined. This can be combined with historical sources to determine when the coin was likely struck. Archaeologists can use the evidence to identify or narrow date ranges of historical significance.
