Abstract Afro-Caribbean ware is Caribbean-made pottery manufactured both at the craft and industrial scale by enslaved and free potters of African descent. Previous sourcing studies have shown historic variation in centers of production and market distribution of these wares across the Caribbean. We used Neutron Activation Analysis (NAA) on a clay sample and 13 low-fired coarse earthenware sherds excavated from the historic-period Jackson Wall Manor site on Grand Cayman. We found that the Grand Cayman clay was compositionally inconsistent with any previously analysed ceramic sherds in the University of Missouri Research Reactor (MURR) NAA Caribbean database, and that the ceramic samples excavated on Grand Cayman showed high statistical correlation with Jamaican ceramic groups. These findings suggest that coarse earthenware on Grand Cayman was transported from Jamaica, a nearby colony with established potteries and markets, rather than being produced locally. Jamaican yabbas, which combined African and European manufacturing technique and forms, were imported into Grand Cayman to fit local needs.

Tracing fineware production in the Neo-Assyrian empire: Neutron activation analysis of common and Palace Ware in the upper Tigris River Valley, Turkey
In the Iron Age, the Neo-Assyrian empire (c. 900–600 BC) conquered territory across southwest Asia and established regional capitals along its borders to secure its gains. Governors at these centers oversaw resource extraction and craft production for shipment to the imperial heartland in modern-day northern Iraq. Metals and textiles were the crafts most carefully managed by the administration. We know less about centralized control over ceramic production but hypothesize that fineware production and distribution would have been of interest to imperial administrators. A fineware type known as Palace Ware has been found throughout the empire and is considered an indicator of elite Assyrian dining traditions. Excavations at one regional capital, Ziyaret Tepe (ancient Tušhan) produced pottery of various skill levels used by residents. In this study neutron activation analysis (NAA) was used to characterize and compare the fabrics used to make Palace Ware vessels with more common wares to see if the former vessels were imported from the imperial heartland. Palace Ware is macroscopically distinct, but this does not always indicate an import. Chemical composition of the samples fell into four main groups, and both Palace and common ware were found to have similar compositions. Comparison of these data with those from contemporary sites showed that the two main Ziyaret groups matched the chemical composition of pottery from the Assyrian capitals of Nimrud and Nineveh. Our conclusions show that there is considerable homogeneity in the clays of the upper Tigris river valley in Turkey and the lower Tigris in northern Iraq. Given this similarity, it is possible that Palace Ware at Tušhan was produced locally, imported, or both. If it was manufactured locally, as has been shown at the urban center of Tell Sheikh Hamad, potters in the imperial peripheries may have produced fineware pottery independent of direct imperial control.

Abstract This study centers on a sample of ceramics (n = 37) from the site of San José Cuautitlan and contextualized within a much larger database of Formative ceramics (n = 1242), mostly from greater central Mexico. The sample was assayed through neutron activation analysis (NAA), with a subsample made into thin sections for petrographic analysis. In this article, we (1) situate the sample from San José within the longer history of ceramic traditions over the Formative period in the Basin of Mexico, (2) assess the pottery production recipe employed at San José in comparison to the composition of ceramics from neighboring segments of the Basin, and (3) source a sample of 10 Granular White amphora that were imported into the site. We demonstrate a low level of ceramic trade among sites within the Basin of Mexico. We also tentatively source Granular White amphora recovered at the site to central Morelos. Further, we show through a comparison of these Late Formative Granular White specimens to later Classic period Granular Ware from Teotihuacan and other sites that the source of this trade ware changed over time.more » « less

Northern Iraq was the political and economic center of the Neo-Assyrian Empire (c. 912 to 609 BCE)—the largest and most powerful empire of its time. After more than two centuries of regional dominance, the Neo-Assyrian state plummeted from its zenith (c. 670 BCE) to complete political collapse (c. 615 to 609 BCE). Earlier explanations for the Assyrian collapse focused on the roles of internal politico-economic conflicts, territorial overextension, and military defeat. Here, we present a high-resolution and precisely dated speleothem record of climate change from the Kuna Ba cave in northern Iraq, which suggests that the empire’s rise occurred during a two-centuries-long interval of anomalously wet climate in the context of the past 4000 years, while megadroughts during the early-mid seventh century BCE, as severe as recent droughts in the region but lasting for decades, triggered a decline in Assyria’s agrarian productivity and thus contributed to its eventual political and economic collapse.more » « less

Southern Belize has received less archaeological attention than other areas due in large part to its remote location. However, the difficulty in accessing the area in recent times does not necessarily equate to isolation for the Classic Period Maya who lived in what is now the Toledo District. This paper discusses petrographic data collected on ceramic vessels recovered from burial contexts at Uxbenká, Belize. The partial and reconstructed whole vessels from these primary contexts include locally produced vessels that are stylistically and technologically unique to the southern Belize region and vessels produced elsewhere. We use these data to evaluate how local Uxbenká potters produced ceramic vessels for local consumption and to identify long-distance interaction networks between Uxbenká and other regions of the Maya Lowlands. Our data indicate that most of the pottery at Uxbenká was produced locally. However, elite tombs often include both local and non-local vessels. The elites of Uxbenká engaged in interaction with people living much farther afield in regions like the Belize River Valley and possibly Guatemala.more » « less

Zerboni, Andrea (Ed.)Late Pleistocene hunter-gatherers in East Asia adopted pottery, yet the ability to reconstruct circulation, mobility, and exchange has been hampered, in part, due to problematic regional geochronology. The driving forces behind pottery adoption is unclear. The purpose of this study is to test our results of the first systematic petrographic pottery sourcing from the pre-Younger Dryas by utilizing neutron activation analysis. We examine samples from the Sankauyama I site on Tanegashima Island, southern Japan, dating to the Incipient Jomon, ca. 14,000/13,500–12,800 cal BP, with a well-defined geochronology. Our NAA results corroborate with the petrographic study suggesting that pottery was mainly produced in-situ, but some vessels were transported long distances from another island. Changing from high mobility, sedentary Incipient Jomon foragers made pottery, occasionally investing in long-distance ceramic vessel transportation and exchange likely involving ocean crossing. This may be associated with a risk-buffering strategy in the context of rising sea levels and isolation of Tanegashima.more » « less
