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...

The composition and manufacture of early mediaval coloured window glass from Sion (Valais, Switzerland): a roman glass-making tradition or innovative craftsmanship ?

Wolf, Sophie ; Kessler Loertscher, Cordula M. ; Stern, W. B. ; Gerber, Y.

In: Archaeometry, 2005, vol. 47(2), p. 361

Archaeological excavations between 1984 and 2001 at the early Christian cemetery church in Sion, Sous-le-Scex (Rhône Valley, Switzerland), brought to light more than 400 pieces of coloured window glass dating from the fifth or sixth centuries ad. The aims of this paper are threefold: first, to characterize the shape, colour and chemical composition of the glass; secondly, to understand whether...

The Alps - a barrier or a passage for ceramic trade ?

Maggetti, Marino

In: Archaeometry, 2005, vol. 47, no. 2, p. 389-401

The Alps as a barrier: ceramic remnants of the so-called Laugen-Melaun culture (c. 11th to c. sixth centuries bc) can be found in the northern Italy (Trentino/Alto Adige)— eastern Switzerland—Liechtenstein and western Austria region. A petrographic study of 454 sherds from this area covering a time span of 500 years reveals the following. (1) The pottery from the Trentino/Alto Adige...

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...

Interaction and communication among autonomous agents in multiagent systems

Fornara, Nicoletta ; Colombetti, Marco (Dir.) ; Gambardella, Luca Maria (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2003 ; 2003COM002.

The main goal of this doctoral thesis is to investigate a fundamental topic of research within the Multiagent Systems paradigm: the problem of defining open, heterogeneous, and dynamic interaction frameworks. That is to realize interaction systems where multiple agents can enter and leave dynamically and where no assumptions are made on the internal structure of the interacting agents. Such topic...
