An Assessment of the Acid-Extraction Approach to Compositional Characterization of Archaeological Ceramics

Abstract

We criticize the acid-extraction approach to chemical characterization of ceramics previously advocated in this journal by Burton and Simon (1993). The instrumental technique used by Burton and Simon (inductively coupled plasma emission spectroscopy [ICP]) is a highly precise chemical characterization technique, but noise introduced by characterizing acid extracts from sherds nullifies the usefulness of the resulting elemental concentration data for archaeological sourcing.
