Mössbauer and X-Ray Fluorescence Studies of Haltern 70 Amphorae from Roman Hispania Provinces

Abstract

Haltern 70 amphora sherds from Castro do Vieito and from production sites in the Roman provinces Baetica and Lusitania were studied by Mössbauer spectroscopy and XRF. The amphorae were fired under reducing atmosphere and oxidized during cooling down. The firing conditions as well as the Ca content are essential for the colour and the state of iron of the amphorae.
