In 2017, an excavation led by the Groningen Institute of Archaeology and in collaboration with the Tor Vergata University of Rome, took place on two small islands in the Caprolace lagoon (Sabaudia, Italy), where Middle Bronze Age layers had previously been reported. Combining the results of an environmental reconstruction of the surroundings and a detailed study of the pottery assemblages, we were able to trace a specialised area on the southern island, in all probability devoted to salt production by means of the briquetage technique. The latter basically consists of boiling a brine through which a salt cake is obtained. The technique was widespread all over Europe, from Neolithic to Roman Times. Since the evidence points to an elite-driven workshop, this result has deep implications for the development of the Bronze Age socio-economic framework of Central Italy. Pottery evidence also suggests that in the Bronze Age sites along the Tyrrhenian coast of Central Italy where briquetage has already been hypothesised, more complex processes may have taken place. On the northern island, we collected a large number of so-called pedestals, which are characteristic features of briquetage, while chemical analyses point to salt or fish sauce production, like the roman liquamen, in a Middle Bronze Age domestic context.
2017 年，由格罗宁根考古研究所领导，并与罗马托雷安农齐亚大学合作，在卡普罗拉奇泻湖（意大利萨巴迪亚）的两个小岛上进行了挖掘，此前曾在那里报告过中青铜时代的地层。通过对周围环境的重建结果和对陶器组合的详细研究，我们能够在南部岛屿上追溯到一个专门的区域，很可能是用于通过压制技术生产盐。后者基本上是通过煮沸盐水来获得盐饼。该技术在整个欧洲都很普遍，从新石器时代到罗马时代。由于证据表明这是一个由精英驱动的车间，因此这一结果对意大利中部青铜时代社会经济框架的发展具有深远的影响。陶器证据还表明，在意大利中海岸的青铜时代遗址中，已经假设存在压制技术，可能发生了更复杂的过程。在北部岛屿，我们收集了大量所谓的基座，这是压制技术的特征，而化学分析表明，在中青铜时代的家庭环境中，像罗马 liquamen 一样，可能生产盐或鱼露。
