通过有机材料与陶瓷热表面的相互作用而产生的烧后处理经常在民族志文献中描述，但在考古陶瓷组合中很少被发现。为了解决这个问题，本文介绍了一种方法，结合宏观和微观观察和分子分析。对实验陶瓷容器的研究提供了诊断工具，以确定物质的类型，它们的液体或固体状态，以及它们的应用模式，并证明烧制后的处理不能完全防水陶瓷。难以观察宏观和微观证据的烧制后的处理时，锅被解雇减少大气表明，这些过程可能被低估了考古组合。此外，分子热转化标志物，如酮的鉴定，质疑其作为脂肪含量烹饪标志物的经典解释。这项开创性的工作突出了研究烧制后处理的复杂性，这些处理会留下很容易被遗漏或误解的小痕迹。为了解决这个问题，我们提出了一个多分析的方法，这可以作为未来研究的基础，以探索民族考古学文献中提到的完全多样性的后射击治疗。
Post-firing treatments, produced by the interaction of an organic material with the hot surface of a ceramic, are frequently described in ethnographic literature, but have rarely been identified in archaeological ceramic assemblages. In order to address this question, this paper describes a methodology that combines macro- and microscopic observation and molecular analysis. The study of experimental ceramic vessels provided diagnostic tools to identify the type of substances, their liquid or solid state, and their mode of application and attested that the post-firing treatments do not completely waterproof the ceramics. The difficulty to observe macro- and microscopic evidence of post-firing treatments when pots are fired in reducing atmosphere suggests that these processes are probably underestimated in archaeological assemblages. Furthermore, the identification of molecular thermal transformation markers, such as ketones, calls into question their classical interpretation as markers for the cooking of fatty content. This pioneering work highlights the complexity of studying post-firing treatments, which leave small traces that are easily missed or misinterpreted. In order to address this issue, we propose a multi-analytical approach, which can serve as a basis for future studies to explore the full diversity of post-firing treatments mentioned in ethnoarchaeological literature.
