Raw materials from aquatic environments were systematically used for domestic activities even before the appearance of modern humans. Here, the authors analyse the possible use of freshwater mussel valves of the Unio species, whose surfaces preserve marks resulting from their use. They consider the ways in which wear develops on these valves, starting from the comparison between archaeological exemplars and experimental pieces. An experimental programme was developed to record variables such as the procurement of the raw material, the processing of various materials, and the time needed for each operation. Experimental pieces were assessed to document how use-wear develops. The archaeological assemblage from the site of Cheia in Romania (Hamangia culture, fifth millennium cal bc) served as a case study to illustrate the relevance of the results.

从实验中学习：罗马尼亚公元前五千年的 Unio 淡水贻贝壳

甚至在现代人类出现之前，来自水生环境的原材料就已被系统地用于家庭活动。在这里，作者分析了淡水贻贝阀门的可能用途联合物种，其表面保留因使用而产生的痕迹。他们从考古样本和实验件之间的比较开始考虑这些阀门的磨损方式。开发了一个实验程序来记录诸如原材料的采购、各种材料的加工以及每次操作所需的时间等变量。对实验件进行了评估，以记录使用磨损是如何发展的。来自罗马尼亚 Cheia 遗址的考古组合（Hamangia 文化，第五千年公元前) 作为案例研究来说明结果的相关性。
