“…Neutron activation analysis of the clay bodies of 20 ceramic types supported the hypothesis that the ceramics were manufactured in the Tihamah coastal plain of Yemen (2). Petrographic analysis has indicated the presence of at least two production centres for the material, Hays and Zabid (3).…”

. Can. J. Chem. 66, 266 (1988).Microscopic examination and electron microprobe analysis were employed to determine the materials and techniques used to decorate ten glazed types of medieval Islamic ceramics from North Yemen. Eight types were underglaze-painted, one was slip-painted, and one was monochrome glazed. The glazes were of two compositions, soda-silica and lead oxide -silica with annealing temperatures of approximately 835 and 640°C, respectively. The colourants used in the glazes and paints were cobalt (blue), iron (green), copper (green and blue), and antimony (yellow). Where clay slips or slip-paints were present, alumina enrichment of the glaze had occurred during application or firing, and pigment-paints on top of slip grounds masked enrichment. The Mellor ratio for the lead glazes ranges from 0.68 to 0.74 and is well above the acceptable safety limit of 0.5. [Traduit par la revue]

“…Neutron activation analysis determined the A1 content in white pottery to be as high as 30%, in contrast to 8% for red pottery (2). Unfortunately, it is too difficult to cleanly separate slip from glaze in sufficient quantity to determine its trace element concentration for comparison with the data available for white pottery.…”

“…The full suite of elements available using SLOWPOKE‐based INAA was brought to bear on ceramics from Kommos in Crete (Hancock and Betancourt 1987), the Yemin (Hallet et al 1987), Italy (Hancock 1994), Greece (Attas et al 1995) and Ontario/New York (Hawkins 2001). Collaboration with scholars from MASCA in Philadelphia resulted in an extensive study of Neolithic ceramics from Iran (Hancock et al 1989a).…”

This paper describes the archaeometric research conducted at the SLOWPOKE ReactorFacility of the University of Toronto (SLOWPOKE-Toronto) during its existence from 1971 to 1998. The contributions to student teaching and research are described, and the total contribution of the facility to studies of an eclectic assortment of ancient and historic materials is addressed. experimentation, many researchers from a wide variety of disciplines had access to what turned out to be a useful analytical technique.Archaeometric research began in the first year of facility operation, and had a 27-year history, continuing through to the closing of SLOWPOKE-Toronto in late 1998. ARCHAEOMETRIC USAGE PATTERNSThe information presented in this section has been culled from contributions from individual academics to SLOWPOKE-Toronto Annual Reports and the SLOWPOKE Publications collection. It therefore probably represents a reasonable description of what really occurred, somewhat akin to the way in which INAA data describe archaeological materials.Ceramic analyses began in the first year of reactor operation, using a donated 100-channel multichannel analyser ( Thirteen elements were positively identified and there were strong indications of seven more ; Hancock and Franklin 1972). Archaeometrically inclined students, however, did not initiate research projects until the 1974-5 academic year (Czuba 1975;Katz 1975;Stahl 1975), and the first conference presentations were not until 1976 (Hancock 1976a;Hancock and Franklin 1976).A summary of the long-term, archaeometric usefulness of SLOWPOKE-Toronto is presented in Table 1. In this, five-year blocks of numbers are presented for student reports and theses, for conference presentations, and for final publications in journals or conference proceedings. Of the archaeometric student research projects, most were undertaken by undergraduate students (43), with six master's projects (. The last undergraduate report, on the analysis of red glass beads, was by Kwok (1998).In the numbers of student research projects, there was growth over the first decade, followed by consistent output. This continuing archaeometric contribution to the overall research and teaching undertaken at SLOWPOKE-Toronto was noted by a Dean of Engineering, who bemoaned the fact that his faculty was supporting a facility that was being used significantly by non-engineering students. This profession-centric view made no allowances for the many non-engineering students who would later go on to academic and other meaningful employment.The unique hands-on learning opportunities provided by SLOWPOKE-Toronto must certainly have helped the careers of many students. It was also almost the only opportunity that archaeologists got to wear white lab coats.
