By comparing these observations with various reference data (Shepard, 1976;Maggetti, 1982;Duminuco et al, 1998;Gualtieri and Venturelli, 1999;Cairo et al, 2001;Antonelli et al, 2002;Kacim and Hajjaji, 2003;Broeckmans et al 2004;Maritan, 2004;Cultrone et al, 2005 and references herein) and with our own experimental data obtained for clays from Transylvania (Romanian Ministry of Education, Grant 1762), the firing temperatures for the ceramics could be inferred.…”

ABSTRACT.Mineralogical and petrographic studies of Early Medieval potshards exhumed in the Viile Tecii archaeological site (North Transylvania, Romania) show a ceramic body composed of a microcrystalline to amorphous matrix, various clasts and voids. The microscopical features and XRD patterns indicate that illitickaolinitic clays were used as raw materials, together with quartzitic sands as tempering material. The ceramic vessels were obtained with the potter's wheel, but the fabric is only slightly oriented, due either to the fast modeling or to the coarseness of the clayish paste. The thermal alteration of mineral phases points to relatively high firing-temperatures, between 800 and 900°C.

“…The incipient dissociation of calcite during firing depends mainly on fO 2 , as it can be increased from 600°C (oxidizing conditions, fO 2 = 0.2 atm) to 800°C (reducing conditions, temperature dependant Boudouard equilibrium), see Letsch and Noll (1983). However, in Maritan's (2004) experiments, calcite was stable up to 850°C for both oxidizing and reducing firings, whereas Maritan et al (2006) found only smaller differences between the upper stability of calcite under oxidizing (800°C) and reducing (850°C) firing conditions. Reducing conditions prevail in a pottery during firing, as long as the initially present organic matter is not oxidized.…”

Time-temperature evolutions of different parts inside a pot were recorded during three experimental surface (bonfire) firings. The experimental vessels were shaped from a calcareous clay, tempered with 30% vol. of oolithic limestone. The temperature-time recording showed: (1) T max. was reached after 12-22 min and differed between the firings as well as inside individual vessels; (2) the range of the thermal variation within one single firing was found to be as high as 390°C, and up to 220°C on a specific cross-section; (3) the lowest temperature was not systematically recorded in the core of the object, as is generally expected. Under the polarizing microscope, no textural and mineralogical changes were observed in the ceramic bodies. This is sustained by powder X-ray diffraction analyses evidencing no dolomite or calcite breakdown. The presence or absence of specific illite and chlorite peaks can be generally related to T max. and soaking time, but equivalent firing temperature estimations do not match the measured temperatures.

Detailed petrographic and geochemical analysis of 100 sherds of greyware cooking pottery from the large Medieval kiln site of Cabrera D'Anoia has revealed the presence of several compositional groups that are correlated to different phases in the operation of the site. These appear to relate to changes in the extraction of local raw materials for pottery production, concomitant with the development of the workshop over several centuries. Macroscopic, microstructural and mineralogical analyses have permitted the reconstruction of a consistent tradition of ceramic manufacture at Cabrera D'Anoia. Close correspondence between the petrographic and geochemical characterisation of the sherds provides several well-defined compositional reference groups for this major production centre. This is permitting the identification of the products of Cabrera D'Anoia at other rural sites in Catalonia and will provide a firm basis with which to examine the supply and demand of utilitarian pottery vessels in this area during the Medieval period.
