Networks of Consumption: community, materiality and foodways along the ancient Swahili coast

项目目标利用约克大学现有的挖掘材料，利用先进的考古技术，探索Unguja Ukuu遗址进口和当地陶瓷的整个使用周期。它将通过岩相分析和使用磨损分析来确定制造和使用方法，并首次将其与通过残留物分析来确定容器所载的物质结合起来。对公元后世纪伊斯兰贸易网络扩张的研究已经量化了非洲、亚洲和欧洲使用釉面陶瓷的联系。据推测，这些陶瓷是承载高价值无形商品的容器，如葡萄酒，枣糖浆或棕榈油。没有人分析过它们实际上含有什么，或者这些商品如何适应当地的消费或烹饪。当地和进口陶瓷都被视为东非精英盛宴策略的一部分。然而，贸易和当地动态的研究还没有通过探索如何烹饪或使用进口和本地食品的连接。考古陶瓷研究现在提供了潜在的确定陶瓷的生产和使用模式，提供详细的信息，烹饪和消费。桑给巴尔的Unguja Ukuu是一个重要的案例研究，它是一个以利用贸易机会为导向的社会，但与整个东非的消费网络有着密集的联系。目标和方法研究将借鉴现有的挖掘组合Unguja Ukuu，桑给巴尔在约克举行。可获得完整的背景数据，允许在陶瓷类型和沉积背景之间进行采样。这将控制再利用，特别是进口船只的再利用。1）审查东非陶瓷生产和使用的现有知识。借鉴陶瓷类型学和饮食的考古植物学/动物群数据。2）将Unguja Ukuu的陶瓷组合分类为功能类型学东非和海湾地区有既定的类型学，但不包括制造和使用的细节。陶瓷将被组织成类型学类别，并进行宏观分析和使用高倍显微镜分析，以确定生产集群和可能的功能信息。3）调查使用来自Unguja Ukuu的进口和当地船只的食品和美食。将实施完善的协议，以a）同位素区分来自肉类、植物、乳制品和水产脂肪的脂肪酸，B）从产品如葡萄/石榴/罗望子/枣中靶向水果来源的有机酸，c）基于它们的脂肪酸和三酰甘油分布来区分植物油（棕榈油、橄榄油等）。将对本地（100个）和进口船只（100个）的代表性样本进行分析，以确定其原始内容;数量足以检查不同的背景，子形式和保存条件。BioArCh学生预算将用于购买基本消耗品。4)将Unguja Ukuu产生的数据与印度洋比较框架相联系将在Unguja Ukuu、东非其他地点和印度洋世界之间进行比较。这将允许高分辨率结果外推到已识别出类似陶瓷但未进行详细分析的位置。这将使用Wynne-Jones之前收集的数据、英国、东非和海湾的博物馆藏品。Outcomes 1。关于非洲和国际背景下的研究成果以及方法的学术文章，包括岩相学、使用磨损和识别贸易中的食品（葡萄酒、枣、棕榈油）和当地陶瓷（小米、大米）。为未来陶瓷研究收集岩相学和使用磨损参考资料3。在桑给巴尔博物馆展出（每年180 000名参观者），作为青年大学现有合作的一部分4。为英国和坦桑尼亚学校制作在线教育资源

Project AimUse cutting-edge archaeometric techniques to explore the full cycle of use for imported and local ceramics at the site of Unguja Ukuu, using existing excavated materials at the University of York. It will identify methods of manufacture and use through petrographic and use-wear analysis and for the first time put this together with identification of what the vessels contained through residue analysis. RationaleStudies of the post-7th century AD expansion of Islamic trading networks have quantified connections using glazed ceramics across Africa, Asia, and Europe. It is assumed that these ceramics were containers carrying high-value invisible commodities such as wine, date syrup or palm oil. There has been no analysis of what they actually contained or how these commodities fitted into local consumption or cuisine. Both local and imported ceramics have been seen as part of elite feasting strategies in East Africa. Yet, studies of trade and of local dynamics have not been connected through exploration of how imported and local foodstuffs were cooked or used.Archaeometric ceramic studies now offer potential to identify patterns of production and use for ceramics, giving detailed information on cuisine and consumption. Unguja Ukuu in Zanzibar is an important case study, as a society oriented towards exploiting opportunities for trade yet with a dense web of connections to consumption networks throughout East Africa. Objectives and methodsThe research will draw on an existing excavated assemblage from Unguja Ukuu, Zanzibar held at York. Full contextual data are available, allowing sampling across ceramic types and contexts of deposition. This will control for reuse, particularly of imported vessels.1) Review of existing knowledge on production and use of ceramics in East AfricaDraw on ceramic typologies and on archaeobotanical/faunal data on diet.2) Categorise the ceramic assemblage from Unguja Ukuu into functional typologiesEstablished typologies exist from East Africa and the Gulf, but do not include detail on manufacture and use. Ceramics will be organised into typological categories and analysed both macroscopically and using high-powered microscopy to identify clusters of production and information on probable function.3) Investigate the foodstuffs and cuisines for which imported and local vessels from Unguja Ukuu were usedWell-established protocols will be implemented to a) isotopically distinguish fatty acids derived from meat, plant, dairy and aquatic fats, b) target fruit-derived organic acids from products such as grape/pomegranate/tamarind/date, c) distinguish plant oils (palm, olive etc) based on their fatty acid and triacylglycerol distributions. A representative sample of local (100) and imported vessels (100) will be analysed to determine their original contents; a number sufficient to allow examination of different contexts, sub-forms and preservation conditions. The BioArCh student budget will be used to purchase essential consumables. 4) Link the data produced from Unguja Ukuu to a comparative Indian Ocean frameworkComparisons will be made between Unguja Ukuu, other sites in East Africa and the Indian Ocean world. This will allow the high resolution results to be extrapolated to locations where similar ceramics have been identified but not subjected to detailed analysis. This will use data previously gathered by Wynne-Jones, museum collections in the UK, East Africa & the Gulf.Outcomes1. Academic articles on outcomes of research in African and international contexts, and on methods, including petrography, use-wear and identifying foodstuffs in trade (wine, dates, palm oil) and local ceramics (millet, rice).2.
