Discontinuing Traditions: Using Historically Informed Ethnoarchaeology in the Study of Evros Ceramics

Ethnoarchaeological studies of pottery primarily focus on the ethnographic present, often disregarding the role of history in the production of material culture. This paper integrates information from historical sources and ethnographic interviews to better understand stylistic ceramic change. Beginning in the 1920s, undecorated pots largely replaced decorated pottery in the region of Evros, Greece. I argue that historically informed ethnoarchaeology provides the key to documenting and understanding the concomitant changes in the social context of pottery production and consumption and the distribution of material culture.

贾湖遗址出土古陶产地的初步研究

利用等离子体发射光谱 (ICP),对舞阳贾湖遗址出土古陶样品进行了常量元素和微量－痕量元素的测试分析,结合考古发掘资料和考古学分析,采用聚类分析方法,系统研究了贾湖遗址出土古陶的矿料来源,发现贾湖制陶业基本处于家庭制陶阶段。本文还将贾湖遗址与大河村遗址和西山遗址的出土古陶产地进行了比较研究。结果表明,这些遗址的陶器在聚类分析谱系图上被明显地分为相应的三类,它暗示上述三处遗址间无明显文化交流关系。     

Technological Characterization of Campanian Pottery of Type A,B and C and of Regional Products from Ancient Calabria (Southern Italy)

Sherds of Campanian pottery were studied by SEM‐EDX. SEM images show that slips of Campana C are scarcely sintered and are thicker than the well vitrified coatings of Campana A and B and imitations of Campana B. Slips of products with a grey slip on a grey body are very thin and well vitrified. EDX analyses indicate that slips are richer in aluminium and iron, and poorer in silicon and calcium, with respect to the bodies. Higher potassium is also found in all of the coatings except those of Campana A. Here relatively high sodium makes the total alkalis comparable with those of the other products, except Campana C, where it is somewhat lower. Measurement of thermal expansion and X‐ray powder diffractograms suggest that firing temperatures were mostly in excess of 900°C, but some samples of Campana C seem to have been fired below 800°C.     

Neutron activation analysis of fine grey pottery from Conimbriga,Santa Olaia and Tavarede,Portugal

The concentrations of two major elements and thirteen trace elements in 73 selected sherds of fine grey ware from the Iron Age and Roman period, excavated at Conimbriga, Santa Olaia and Tavarede, Portugal, were determined by instrumental neutron activation analysis. These concentrations were used to calculate distance matrices which were then subjected to cluster analysis employing SAHN and k-means methods, as well as to principal components analysis, to group the sherds according to the overall similarity of their compositional characteristics. The results showed that equivalent groupings appeared regardless of the taxonomic method used. Two major clusters were recognized corresponding to two different sites, namely Conimbriga and Santa Olaia, suggesting that the ceramics from these sites were made locally. No significant differences in compositional patterns were observed between iron age and roman sherds from Conimbriga.     

Strength,Toughness and Thermal Shock Resistance of Ancient Ceramics,and Their Influence On Technological Choice

The basic underlying theory for the strength, toughness and thermal shock resistance of brittle multiphase clay ceramics, together with the measurement procedures to determine these parameters, are first outlined. Published experimental data obtained for test bars containing different types of temper and fired to a range of temperatures are then compared both with theoretical predictions and between themselves. The results confirm that to produce pottery with high strength requires high firing temperatures and low temper concentrations. Conversely, to produce pottery with high toughness and thermal shock resistance requires low firing temperatures and high temper concentrations, with platy or fibrous temper being most effective. There is no convincing published evidence that strength and toughness requirements were a significant factor in determining the technological choices (clay type, temper type and concentration, and firing temperature) in the production of pottery used as containers for transport and storage. In contrast, the routine use of high temper concentrations and low firing temperatures in the production of cooking pots suggests that the requirement for high thermal shock resistance was a factor that at least influenced technological choice in this case. In addition, there is some evidence that limestone and shell were, on occasions, deliberately chosen as temper in cooking pots. The need to take into account the crucial role that the full range of environmental, technological, economic, social, political and ideological factors have in influencing technological choice is also emphasized. This review highlights the fact that our current understanding of the factors determining strength, toughness and thermal shock resistance of clay ceramics is still far from complete. Further systematic measurements of these parameters, together with the establishment of a systematic database of the range of technological choices associated with the production of cooking pots, are therefore to be encouraged.     

略论韩国百济故地出土的中国陶瓷

中国六朝各朝代一直与朝鲜半岛保持着密切的关系,尤其与百济之间有着不同形式的交往。迄今为止,在韩国百济故地已出土了不少中国六朝时期的陶瓷,这些器物可证实当时文化交流的部分情况。本文对其中保存较完整、时代较明确的几件器物进行了初步地分析和比较,并试图探讨这些器物的输人途径、烧制窑口、年代等问题。随着中国国内对该时代墓葬和陶瓷研究的进一步深入,必将对韩国的有关研究起到重要的参考和借鉴作用。
