Assessment of the amphora spectrum in a rural Late La Tène settlement at Reinach-Nord, Basel region, Switzerland

Thierrin-Michael, G. ; Martinez, D. C. Tretola ; Serneels, Vincent

In: Journal of Archaeological Science: Reports, 2018, vol. 21, p. 1055–1063

The relatively high quantity of amphorae among the ceramic material discovered in Late La Tène structures at Reinach-Nord appears quite unusual at a rural settlement of this period in NE Switzerland and warranted further investigation. How does the amphora spectrum compare to the one of earlier or later sites in the region? On earlier settlements in the area between Lyon, the Upper Rhine...

Swiss stained-glass panels: an analytical study

Machado, Andreia ; Wolf, Sophie ; Alves, Luis C. ; Katona-Serneels, Ildiko ; Serneels, Vincent ; Trümpler, Stefan ; Vilarigues, Márcia

In: Microscopy and Microanalysis, 2017, vol. 23, no. 4, p. 878–890

The history and iconography of Swiss stained glass dating between the 16th and 18th centuries are well studied. However, the chemical and morphological characteristics of the glass and glass paints, particularly the nature of the raw materials, the provenance of the glass, and the technology used to produce it are less well understood. In this paper, we studied two sets of samples from...

The massive production of iron in the Sahelian belt: Archaeological investigations at Korsimoro (Sanmatenga – Burkina Faso)

Serneels, Vincent

In: Materials and Manufacturing Processes, 2017, vol. 32, no. 7–8, p. 900–908

The large smelting site of Korsimoro was investigated during two fieldwork campaigns in 2011 and 2012. Four different technical traditions are identified. Each is characterized by the spatial organization of the working area, the architecture of the furnace, and the assemblages of wastes. Each technical tradition corresponds to one chronological phase. Phase KRS 1 lasted between 600 and 1000...

Reconstructing the geomagnetic field in west africa: first absolute intensity results from Burkina Faso

Kapper, Lisa ; Donadini, Fabio ; Serneels, Vincent ; Tema, Evdokia ; Goguitchaichvili, Avto ; Morales, Juan Julio

In: Scientific Reports, 2017, vol. 7, p. 45225

We present absolute geomagnetic intensities from iron smelting furnaces discovered at the metallurgical site of Korsimoro, Burkina Faso. Up to now, archaeologists recognized four different types of furnaces based on different construction methods, which were related to four subsequent time periods. Additionally, radiocarbon ages obtained from charcoal confine the studied furnaces to ages...

Directional changes of the geomagnetic field in West Africa: Insights from the metallurgical site of Korsimoro

Donadini, Fabio ; Serneels, Vincent ; Kapper, Lisa ; El Kateb, Akram

In: Earth and Planetary Science Letters, 2015, vol. 430, p. 349–355

This work shows the first archeomagnetic directions from Western Africa measured on 32 iron smelting kilns dated between 650 and 1800 AD. The archeological excavation of the vast metallurgical site of Korsimoro established the existence of four distinct iron-smelting techniques. The time-frame of each technique could be clearly determined with radiocarbon dating. Many of the kilns investigated in...

The origin of 18th–19th century tin-glazed pottery from Lorraine, France

Maggetti, Marino ; Rosen, J. ; Serneels, Vincent

In: Archaeometry, 2015, vol. 57, no. 3, p. 426–452

Forty-eight tin-glazed ceramic fragments (faiences) from Lorraine, found in excavations or pertaining to objects in collections, were subjected to X-ray fluorescence analysis to determine the bulk, major, minor and trace element compositions. Sixteen superficially clay layers from the surroundings of Lunéville and Saint-Clément were also analysed. The faiences are, with four exceptions, MgO...

Composition and technology of 18th century high magnesia faïences from Fulda

Maggetti, Marino ; Serneels, Vincent ; Stasch, Georg

In: Journal of Archaeological Science: Reports, 2015, vol. 2, p. 40–50

In 1996, archaeological excavations close to the ancient Fulda faïence manufacture site unearthed a rich deposit of faïence wastes (biscuits, faïences, technical ceramics). The manufacture was founded in 1741 by Prince Abbot Amand von Buseck and closed down in 1761. This first archaeometric study of a German faïence manufacture included 31 samples produced between 1742 and 1760. Analytical...
