The introduction of the rotary quern into the Iberian Peninsula during the Iron Age represents a great technological innovation with regard to processing cereals. These mechanisms arrived several centuries later in the Canarian archipelago with the first North African colonists. Contacts with the African continent appear to have either been cut off or minimised a short time later, obliging the colonists to subsist autonomously and adapt to the features of the new territory. Moreover, the archipelago's volcanic character does not offer minerals that could be transformed into metals obliging the new populations to resort to stone tools, an adaptation evidenced by the manufacture of rotary querns. Currently few technological studies of these querns have combined experimental work with hypotheses stemming from archaeological evidence. This article presents two experimental programs that have attempted to reconstruct the operational sequence (chaîne opératoire) of the two main types of rocks exploited for querns in the Canary Islands: volcanic tuff and vesicular basalt.

铁器时代将旋转机器引入伊比利亚半岛，代表了谷物加工方面的伟大技术创新。几个世纪后，这些装置随着第一批北非殖民者抵达加那利群岛。不久之后，与非洲大陆的联系似乎被切断或最小化，迫使殖民者自主生存并适应新领土的特征。此外，群岛的火山特征并不提供可以转化为金属的矿物质，这迫使新人口不得不求助于石制工具，旋转奎恩的制造证明了这种适应。目前，很少有对这些问题的技术研究将实验工作与考古证据产生的假设结合起来。本文介绍了两个实验计划，试图重建加那利群岛用于奎恩斯开采的两种主要岩石类型的操作序列（ chaîne opératoire ）：火山凝灰岩和多孔玄武岩。
