ABSTRACT Despite decades of study of post-depositional surface modification by lithic use-wear analysts, the impact of heat remains underexplored. In this paper, we present the results of an experiment designed to test the effects of heat on chert tools with well-developed wood polish. We placed 50 flakes at varying positions in and around a wood fueled hearth. Visual examination of the wood polish before and after exposure to the fire identified no discernable alterations to its texture, brightness, or extent. These results indicate that the specific conditions of thermal alteration reported here may not inhibit lithic use-wear analysis on fine-grained chert implements with wood polish, ultimately highlighting the need for further experimentation on additional lithic materials and types of polish. Given that this experiment was inspired by analysis of stone tools from ephemeral hunter-gatherer camps, we consider the implications of this experiment for the analysis of chert tools at these sites.

热对锂微磨损痕迹的影响：实验评估

摘要尽管石器使用磨损分析人员对沉积后表面改性进行了数十年的研究，但对热量的影响仍未得到充分研究。在本文中，我们介绍了一个实验结果，该实验旨在测试发达的木器上光对石工具的影响。我们将50片薄片放在燃木壁炉中和周围的不同位置。在暴露于火中之前和之后对木材上光剂进行目视检查，发现其质地，亮度或程度没有明显变化。这些结果表明，此处报道的热变化的特定条件可能不会抑制用木蜡打磨的细粒t石工具的石器使用磨损分析，最终强调需要对其他石器材料和上光剂类型进行进一步试验。
