“…In the firing process of calcareous pastes, Fe ions incorporate mainly into the structures of gehlenite and pyroxenes giving a whitish to brownish color rather than forming red hematite in an oxidizing firing, depending on the iron oxide size (18,20,48,49). Nevertheless, small amounts of hematite may crystallize with high oxidizing firings, so this phase is also present in several samples.…”

“…Chemical analysis of the samples is not sufficient to study the technology of pottery fabrication (18)(19)(20)26). For instance, similar elemental compositions may give rise to different potteries as the mineralogical phase assemblage depends upon the raw clay mineralogy and the firing temperature.…”

“…In general, a good correlation between the higher firings and the paler pastes was found. The firing temperature, FT, of ceramics can be estimated within a certain range by using XRPD data (18,20,26,(50)(51)(52). Although FT estimations are widely made and used, sometimes are criticized (53).…”

“…The compositional data from Table II were processed statistically in order to check their homogeneity using MATLAB®. Lack of homogeneity in the analyzed sample is likely due to different raw materials and, therefore, different provenances may be suspected (18)(19)(20). First of all, the P 2 O 5 content was checked, because high phosphorous content usually indicates external organic contamination, i.e.…”

“…Su aplicación sistemática proporcionó no solamente su caracterización sino también la discriminación de distintas fábricas cerámicas, en cada uno de los centros de producción, cuyas características a priori parecían muy similares (9,10). Igualmente, estos resultados suministraron aspectos de gran interés acerca de las características de las materias primas y los procesos empleados en su manufactura.…”

En el marco de un extenso programa de investigación arqueométrica de la producción de centros alfareros celtibéricos, ubicados en el Sistema Ibérico Central, se ha avanzado en el estudio de dos de estos alfares: La Rodriga (Guadalajara) y Allueva II (Teruel). Se han analizado cuarenta y cuatro muestras representativas de distintos tipos de cerámicas de ambos talleres, cuya cronología de funcionamiento se centró entre los siglos III-II a. C. La caracterización se ha dirigido al análisis químico mediante Espectrometría de Masas con Plasma de Acoplamiento Inductivo (ICP-MS), realizando un tratamiento estadístico multivariante para diferenciar entre los materiales cerámicos y discriminar distintos grupos compositivos en cada centro alfarero. El estudio se ha completado con la caracterización petrográfica, observaciones texturales, medición del color de las cerámicas y el análisis mineralógico por DRX. A partir de las variaciones compositivas identificadas en sus elementos mayoritarios, minoritarios y trazas, se han establecido dos subgrupos para La Rodriga, discriminados frente al grupo constituido por las cerámicas de Allueva II. Estas variaciones son concordantes con las características petrográficas de las fábricas cerámicas y la composición mineralógica de las piezas. Los resultados obtenidos han permitido completar la investigación arqueométrica inicial y servirán de base para el estudio de las influencias culturales y comerciales en este importante territorio de la Celtiberia.

Celtiberian ceramic productions from the Central Iberian range (Spain): Chemical and petrographic characterizationAs part of an extended program on archaeometric research of the Celtiberian production centres situated along the Central Iberian Range, ceramic fragments of different vessel types from two selected Celtiberian workshops were analyzed: La Rodriga (Guadalajara, Spain) and Allueva II (Teruel, Spain), dated from the 3 nd to the 2 st centuries BC. The characterization was focused on the chemical analysis by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), and subjected to commonlyused multivariate statistical methods to distinguish between ceramic materials and to discriminate among different compositional groups in each production centre. The analysis was completed by performing petrographic characterization, textural observations, colour measurement and mineralogical analysis of the pieces by means of XRD. The compositional variations from major, minor and trace elements allowed to establish two subgroups in La Rodriga and one ceramic group in Allueva II. The chemical composition differences were confirmed by the petrographic characteristics and the mineralogical composition of the ceramic fabrics. These results enabled us to complete the preliminary archaeometric study in order to improve the knowledge on cultural and commercial influences in this imp...

Raman microspectroscopy has been employed for the characterization of 16 samples of ancient Iberian pottery. These sherds of vessels were found in the archaeological site of La Vispesa in Tamarite de Litera (Huesca, Spain) and correspond to the Iberian time. The composition of certain mineral phases such as non-plastic inclusions has been particularly considered with a view to obtaining information on the source materials and their provenance, as well as the technological conditions of ceramic production. Typical minerals such as calcite and quartz were found in most of the samples. The presence of anatase in a group of the samples suggested the use of different clays in the production of the vessels. Furthermore, the absence of rutile in these samples, together with the identification of calcite, is indicative of a mild firing temperature. Hematite was identified in all samples, both in the ceramic body and in the decoration. Differences in the position of the bands and relative intensities characterized hematite in terms of crystallinity and origin. An attempt to assign the samples to different production centers was made according to their chemical composition and morphology.
