FIRING ANALYSIS OF SOUTH‐EASTERN MISSOURI INDIAN POTTERY USING IRON MÖSSBAUER SPECTROSCOPY *

Abstract

The Mössbauer spectra of prehistoric pottery and clay from the Malden Plain of south‐eastern Missouri, USA, were examined. The pottery dates from AD 500 to 1400. The earlier sherds were tempered with sand and the later ones with shell. The sherds and clay contain a mixture of illite, smectite, and kaolinite. Most samples of clay and sherds contained both ferric and ferrous species. The spectral parameters for the ferric species were %DLEQ∼0. 7—1.1 mms‐1 and δ∼0.0–0.3 mms‐1 for the ferrous species, ΔEQ∼2.1–2.7mms‐1 and δ∼0.7–1.0mms‐1. The ferric to ferrous ratio is more accurately determined from the spectra than from consideration of the colour or the firing core of the sherds, which are not always related to the iron species ratio. Differences among sherds in the ferrous ΔEQ can be related to original temperature of heating but with low precision.
