Pottery, production and petrography
In the last two weeks the study of pottery from Tell Basta moved in new directions. Mandy’s work was supplemented with new data related to the work of Yiannis, a very recent member of the excavation team specializing in ceramic microscopic analysis. Their collaboration led the research along new paths and enriched the potentials of exploring the existing and newly discovered material from the site in a number of different ways. The results of this collaboration appear to be very promising.
Mandy and Yiannis reexamined and restructured the existing fabric groups, and concluded that many of the locally produced fabrics that had already been described, could perhaps be connected together to form a larger category; on the other hand, many of the imported ceramic finds need to be revised into larger fabric groups. The latter ceramic finds constitute a number of wares coming from the broader Northern Egyptian region, or other areas in the vicinity of the Eastern Mediterranean, such as Greece and the Levant.
Mandy and Yiannis also focused on re-examining the existing fabric descriptions by a method of chemical identification of calcareous inclusions, based on the reactions of potsherds with dilute hydrochloric acid. These simple tests showed interesting results. It seems likely that in the near future some of the existing fabric categories of Northern Egyptian clays may need to be revised and expanded with information from sciences such as geology and geochemistry.

In order to investigate the material in more detail, Mandy and Yiannis traveled to Cairo and visited the laboratory of the French Institute (IFAO). There, the two members of the Tell Basta team had the opportunity to examine thin sections of imported pottery which had already been sampled (mainly amphorae and small finewares), and also to compare the existing local fabrics at the Tell with other material discovered in other excavations all around Egypt, such as the Mareotic region and Tebtynis. The analysis of the thin sections indicated a variety of imported fabrics arrived at the Tell during the Late and Ptolemaic periods and Roman times, which definitely complies with the mobility of goods and the advanced transportation networks existing during those times.

A number of new and interesting questions are now arising at the site, which require further investigation. Is local production taking place at the Tell during the above mentioned times? Could this production be identified by its own distinct characteristics? A significant problem is that large-scale local production cannot be fully investigated in the archaeological sense. A lot of the areas that may be possible production sites are located at the edges of the existing archaeological site of Bubastis, perhaps under modern buildings; therefore, the potential of excavating such areas is fairly limited. The two archaeologists are now exploring the possibility of defining production with the use of other scientific methods, such as thin section analysis (also known as petrographic analysis) and X-Ray Fluorescence Analysis (known as XRF). Mandy’s experiments in producing pottery from local clays selected from various layers of the soil are expected to play an important role in establishing comparisons.
The two archaeologists believe that in the coming seasons the investigation of pottery at the site of Tell Basta will lead to excellent results. Until then, the examination of the ceramic finds will continue along the lines of the excavations, supplemented with new scientific methods of analysis.
Besides the scientific analysis the archaeological record of pottery continues by classifying, drawing, and photographing the material excavated during the last seasons.
