Nondestructive determination of major and trace elements within voluminous materials has been demonstrated by prompt γ-ray
neutron activation analysis. Some fragmented pieces of pottery bowls considered to have been produced in the late 18th century
were analyzed by a new internal monostandard method, and noticeable differences of the elemental contents and significant
correlations of the elemental distributions were observed among the samples. The possibility of identification of producing
areas of unearthened material is demonstrated by the analytical results and the applicability of this method to the investigation
of precious samples in a completely nondestructive way is verified in practice.
