Mössbauer and XRD study of Roman amphorae buried in the sea for two millennia (2016)
DOCUMENT Citation Only Ursel Wagner. Friedrich Wagner. Werner Haeusler. Benilde Costa. Jean-Yves Blot.

A decade ago Roman Haltern 70 amphorae were found in the sea near Cortiçais on the Atlantic coast of Portugal. They stem from a shipwreck dated to between 15 BC and 15 AD. We have studied fragments of these amphorae by Mössbauer spectroscopy and X-ray diffraction to look for changes caused by two millennia of exposure to seawater. For comparison we studied Haltern 70 type amphorae excavated on land at Castro do Vieito in the north of Portugal. The sherds show a layer structure with 2 to 3 mm...


Mössbauer, XRD and XRF study of Roman amphorae and amphora kilns from the Roman provinces of Baetica and Lusitania andclays (2015)
DOCUMENT Citation Only Ursel Wagner. Benilde Costa. Werner Häusler. A. Silva. Friedrich Wagner.

Roman Haltern 70 type amphorae found at Castro do Vieito, an archaeological site in the north of Portugal, in the former Roman province of Lusitania, were studied by 57-Fe Mössbauer spectroscopy, X ray diffraction and X ray fluorescence with the aim of elucidating their firing conditions and their site of production. For comparison, sherds found at eight kiln sites in the south of Spain, in the former Roman provinces of Baetica and Lusitania, were studied. Moreover, clays collected near the kiln...
