For the first time, residue‐analysis results of a red‐rim bowl discovered at Qubbet el‐Hawa in Aswan, Egypt, are discussed alongside the thermal characterization of unpublished pottery bowls of the Old and Middle Kingdoms from the same site. Scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX) and X‐ray diffraction (XRD) analysis were performed to provide fabric description of the bowls. The results show the presence of 4‐heptenoic and 4‐decenoic acids. The Old Kingdom bowl showed a firing temperature range of 800–850°C, while the Middle Kingdom example was fired to higher temperatures. This is a suggested explanation of the decrease in the use of red coating as a surface treatment after the Old Kingdom.

识别船只的用途并解释从旧到中王国的生产工艺的变化：来自埃及阿斯旺的库贝贝·埃尔·哈瓦的有机残余物分析，织物和锅架的热特性

首次讨论了在埃及阿斯旺的Qubbet el-Hawa发现的一个红边碗的残留分析结果，以及对同一地点未出版的中，古王国陶器碗的热学特征。进行了能量色散X射线光谱（SEM-EDX）和X射线衍射（XRD）分析的扫描电子显微镜，以提供碗的织物描述。结果表明存在4-庚烯酸和4-癸烯酸。老王国碗的烧成温度范围为800–850°C，而中王国碗的烧成温度更高。这是旧王国之后减少使用红色涂层作为表面处理的建议解释。
