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of a red‐rim bowl discovered at Qubbet el‐Hawa in Aswan, Egypt, are discussed alongside the thermal characterization of unpublished pottery bowls of the Old and Middle Kingdoms from the same site.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.
