Glazed ceramics are a common material analyzed through geochemistry, whether in the form of tableware collected during excavations or tiles observed as part of architectural features. Within the framework of these studies, measuring the thickness of the transparent glaze is one of the useful variables available for the characterization of the ceram...
The Ychsma society was one of the most important civilizations developed between 900 and 1532 CE in Lima, the present Peruvian capital, situated on the central coast of Peru. The Ychsma territory included the lower basin of the Rímac and Lurín valleys in the current city of Lima (Peru). Around 1470 CE, the Ychsma region was conquered and placed und...
In this paper, we focus on the industrial production of porcelain in the Bordeaux area (France) in the 19th century. Our main objective is to assess the evolution of production technology of the same manufactory over a period of more than 40 years. A multi-analytical approach was used to investigate glazes and bodies of thirty-four sherds of biscui...
The aim of this research is to investigate the influence of NaCl on the colours and chemical composition of Ca-rich ceramic bodies. The addition of salt to ceramics is a practice that has been observed in several potter communities where the addition of salt is explicitly intended to whiten ceramics. In order to conduct this research and characteri...
This paper aims to apprehend evolution of ceramic manufacture strategy in the Johnston‐Vieillard manufactory (Bordeaux, France), which produced white earthenwares between 1835 and 1895. Glazes of fragments of seventy‐six sherds, dated from different periods of the 19th century and found in excavations were characterised thanks to combined chemical...
Combined analysis methods such as optical microscopy (OM), cathodoluminescence (CL) microscopy, X-ray diffraction (XRD), and scanning electron microscopy–energy dispersive X-ray spectrometry (SEM–EDX) have made it possible to obtain the first physico-chemical data of Dacian potsherds, exhumed at the archeological site of Ocnița-Buridava, Romania; t...
In this paper, we focus on the industrial production of white earthenware in the Bordeaux area (France) in the 19th century. Our main objective is to assess the evolution of production technology. A multi-analytical approach was used to investigate bodies of 150 fragments found in archaeological context. The microstructural, chemical and mineralogi...
BACKGROUND: From the 1st to the 3rd centuries A.D., the territory of Istria (present-day Croatia) was a prominent area of olive oil production. Archaeologists have identified the so-called Dressel 6B amphora as the main container used in the transport and trade of this oil. So far archaeology and epigraphy have helped identify probable sources of p...
Two-colour tiles were produced in abundance in France and England during the thirteenth and fourteenth centuries AD. They replaced the mosaic, hand-incised and counter-relief tiles that had been developed since the twelfth century. These tiles proved very successful and many regional styles of decoration for religious and secular opulent edifices....

One of the restoration processes of the buildings covered with glazed ceramics consists in replacing the missing elements. This way of making runs up against the problem of lack of data concerning the materials and, more generally, their old techniques of manufacture. For this aim, we undertook the study of a four differently coloured zelliges (gre...
IBISA (Image-Based Identification/Search for Archaeology) is a research project supported by the French CNRS. The corresponding software tool manages databases of digital images of archaeological objects, and allows the user to perform searches by examples. For now, the system works with ancient (greek, roman) coins, and the generalization to medie...
Matériau de luxe à l’origine, la faïence en France connaît une évolution technologique en croissante complexification qui correspond en fait à celle des Temps modernes, et court jusqu’à la mise en place de la société industrielle à la fin du XIX
e
siècle. Considéré comme le « berceau de la faïence française »
puisqu’il a permis l’installation défi...
Parmi les matériaux de l‘architecture, les céramiques glaçurées constituent, une « constante » des cultures qui se sont succédé, non seulement sur le pourtour de la Méditerranée mais également dans les pays d’Asie centrale et ceux qui sont compris entre ces deux régions du monde. Une céramique glaçurée comporte un décor, souvent d’une extrême subti...
The instability of the iron oxides make it very difficult to obtain the colour red in single- fired faïence. In this experiment, various samples of archaeological faïence from the 18th and 19th centuries were analysed (BSE images by SEM and Raman spectrometry). Before the 1760’s, the results obtained by faience manufacturers were various and more o...
At the end of 14th century, ceramists from Valencia (Spain) will export their know-how to France at the request of the duke Jean de Berry (1340 - 1416). New materials and advanced techniques arc thus put in an exchange context between two European areas (Gerona and Bourgogne). A characteristic of the produced glazed ceramics is to present a blue de...
Because typological and iconographic data are insufficient to distinguish Aghlabid and Fatimid production centres of green-and-brown-decorated glazed ceramics from Raqqada (IXth-Xth c.) and Sabra Mansouriya (Xth-XIth c.) in Ifriqiya (Tunisia), we tried to differentiate these productions by physical properties. Both centres arc geographically close...
Two series of Zelliges belonging to the Filalia and Bou-Inaniya Medersas
(14th-century) in Meknes city have been studied in order to describe
precisely the colour of the glazes and to identify the chromogen agents
responsible for these colours. The glaze colours are physically studied
by the determination of their chromatic coordinates using chroma...
On s'interroge sur l'origine de la coloration jaune de ceramiques glacurees de Raqqada (Tunisie; IX e - X e siecles). Plusieurs hypotheses ont ete envisagees par les archeologues: presence d'antimoine, de fer ou d'un melange d'antimonate de plomb et d'etain. Raqqada, capitale aghlabide, fondee en 876 ap. J.C. et abandonnee vers le milieu du XI e si...

Ce programme centré sur l’Éthiopie recoit le soutien de l’ANR DIFFCERAM (dir. V. Roux)), de la Fondation Fyssen, du programme franco-éthiopien financé par le Ministère des Affaires Étrangères Late Stone Age Sequence in Ethiopia (direction A. Dessie et F. Bon) et les soutiens scientifiques et logistiques de l’ARCCH (Authority for Research and Conservation of Cultural Heritage ; Ethiopie, Ministry of Culture) et du Centre français des études éthiopiennes (CFEE IFRE 23 et USR 3137) Ce programme est à la croisée d’approches comportementale, ethnologique et archéologique. Comportementale, car à l’échelle de l’individu, il s’agit de caractériser l’apprentissage, de comprendre comment sont acquises des habilitées motrices et d’analyser la capacité de l’individu à modifier son savoir-faire une fois obtenu l’ensemble des habiletés requises. A l’échelle inter-individus, il s’agit d’étudier les modalités et la nature des transmissions et interactions. Ethnologique, car l’analyse des systèmes techniques développés dans les sociétés traditionnelles de la vallée du rift éthiopien permet d’accéder à l’organisation sociale des groupes humains et offre l’opportunité de réfléchir sur les structures de peuplement ou dépeuplement au sein de contextes socio-économiques et environnementaux variés. Archéologique, car la constitution de référentiels actualistes enrichit l’interprétation des faits archéologiques en Préhistoire, ici sur deux aspects : d’une part la constitution de modèles autour des mécanismes sous-jacents à l’emprunt et au non-emprunt de traits techniques et stylistiques entre groupes sociaux distincts ou au sein d’un même groupe social et de modèles autour des conditions à la diffusion de ces traits ; d’autre part la constitution de référentiels techniques sur les procédés de fabrication et d’utilisation de céramiques sans énergie cinétique rotative dans le but d’établir des banques de données, véritables « céramothèques » des macrotraces de fabrication et d’usage utilisables lors d’examen de collections archéologiques. En proposant de construire des référentiels interprétatifs, ces recherches en anthropologie renouvellent les problématiques autour des notions de transferts culturels et s’inscrivent dans les thématiques débattues aujourd’hui au niveau international sur les mécanismes à l’origine de l’évolution des sociétés.
