Investigations into the Elemental Composition of Earthenware Vessels from the Guthe Collection using Instrumental Neutron Activation Analysis

This study undertakes an elemental compositional analysis of Philippine earthenware vessels from the Guthe collection using Instrumental Neutron Activation Analysis (INAA). Unlike foreign trade ceramics, earthenware vessels were locally produced goods but which also played a part in the development of Philippine chiefdoms as an item traded between inland and coastal groups. Thus, the detection of compositional groups within earthenware vessels may help identify patterns of production and exchange. It is also hoped that the results from this pilot study can contribute to the future development of an elemental database for earthenware vessels.
