Pottery kiln and drying oven from Aventicum (2nd century AD, Ct. Vaud, Switzerland): Raw materials and temperature distribution

Eramo, Giacomo ; Maggetti, Marino

In: Applied Clay Science, 2014, vol. 82, p. 16–23

Fireboxes of two pottery structures, excavated in 2002 at Aventicum (at present Avenches), the capital of Roman Switzerland, were studied to understand their function in the artisan quarter. Twenty-one oriented samples underwent petrographical, mineralogical and chemical analyses to determine the nature of the raw materials and the temperature distribution.Both structures are typologically...

The glass-melting furnace and the crucibles of Südel (1723–1741, Switzerland): provenance of the raw materials and new evidence of high thermal performances

Eramo, Giacomo

In: Journal of Cultural Heritage, 2006, vol. 7, no. 4, p. 286-300

Fifty crucible fragments and 10 fragments of the melting furnace of the forest glassworks of Südel (1723–1741, Ct. Luzern), were analyzed by petrographic, mineralogical and chemical techniques in order to assess the temperature reached in the melting chamber and to find out which raw materials were used to make the crucibles and the melting furnace. Since the crucibles were used in the melting...

Pre-industrial glassmaking in the Swiss Jura: the refractory earth for the glassworks of Derrière Sairoche (ct. Bern, 1699–1714)

Eramo, Giacomo

In: Geological Society, London, Special Publications, 2006, vol. 257, p. 187–199

Fragments of the melting furnace and several crucibles of the glassworks of Derrie`re Sairoche are compared with local raw materials. Principal component analysis (PCA) based on the chemical composition and on the grain-size distribution of the archaeological and natural materials demonstrates that the analysed samples were made from the same raw material and that local clayey sands (Hupper,...

The glass-melting crucibles of Derrière Sairoche (1699–1714 AD, Ct. Bern, Switzerland): a petrological approach

Eramo, Giacomo

In: Journal of Archaeological Science, 2006, vol. 33(3), p. 440-452

Forty-three sherds of crucible found in the pre-industrial (1699–1714 AD) forest glassworks of Derrière Sairoche (Ct. Bern, Switzerland) were studied in order to determine the nature of raw materials and the technological aspects of their production and use. The samples were analysed using optical microscopy, XRD, XRF, UV–VIS spectrometry and SEM/EDS. The crucibles were produced with local...

Late Roman cooking pottery from the Tavoliere area (Southern Italy): raw materials and technological aspects

Eramo, Giacomo ; Laviano, Rocco ; Muntoni, Italo Maria ; Volpe, Giuliano

In: Journal of Cultural Heritage, 2004, vol. 5(2), p. 157

This study describes the results of petrographical, mineralogical and chemical analyses carried out on coarse tempered cooking pottery, sampled in the archaeological sites of Herdonia, Posta Crusta (Ordona, FG) and San Giusto (Lucera, FG). From the latter site, two fragments of a pottery kiln, coeval with sherds (IV and V centuries AD), were also investigated. Two groups of clayey...
