ABSTRACT Recent research has demonstrated that Catawba ceramic practices changed abruptly and dramatically after 1759 following a devastating smallpox epidemic and subsequent community relocation. Pottery from the historically documented Catawba town of Old Town and others indicate potters adopted new techniques and styles as they adjusted to new economic and social conditions, including copying European vessel forms, experimenting with new ceramic paste recipes, and utilizing new decorative motifs. The identification of four lead-glazed sherds on otherwise Catawba-looking pale-bodied paste raises the possibility that Catawba potters may have also experimented with lead glazing. This paper presents the results of an elemental analysis of nearly 70 ceramic samples using pXRF and multivariate statistical techniques to identify patterns of production within pale-bodied colonowares. The results indicate that the glazed pottery fragments were made with elementally similar clay used by Catawbas in the Twelvemile Creek locality. I argue that in addition to modifying nearly every aspect of their ceramic repertoire, at least one Catawba potter experimented with lead glazing, providing further insights into the emergent Catawba pottery trade.

十八世纪后期 Catawba 使用便携式 X 射线荧光 (pXRF) 进行的铅釉实验案例

摘要 最近的研究表明，在 1759 年毁灭性的天花流行和随后的社区搬迁之后，卡托巴的陶瓷实践发生了突然而显着的变化。历史记载的卡托巴镇旧城区和其他地方的陶器表明，陶艺家在适应新的经济和社会条件时采用了新的技术和风格，包括复制欧洲的器皿形式、试验新的陶瓷糊剂配方以及利用新的装饰图案。在看起来像卡托巴的淡色糊状物上发现了四块铅釉陶片，这增加了卡托巴陶工也可能尝试过铅釉的可能性。本文介绍了使用 pXRF 和多变量统计技术对近 70 个陶瓷样品进行元素分析的结果，以确定淡体结肠陶瓷的生产模式。结果表明，这些釉面陶器碎片是用十二英里溪地区的卡托巴斯使用的元素相似的粘土制成的。我认为，除了修改他们陶瓷产品的几乎所有方面外，至少有一位卡托巴陶艺家尝试使用铅釉，为新兴的卡托巴陶器贸易提供了进一步的见解。
