| Summary: | The present study discusses the casting of copper axe-ingots in open, wet sand moulds, in an attempt to recreate porous artefacts that have been recovered in Brittany, France. The original axe-ingots are considered to be Irish copper metalwork from the Early Bonze Age. However, these artefacts are not finished objects and are poorly cast. This nevertheless appears to be deliberate because, as it has been argued (see Gandois et al., 2019; Burlot, 2019), they consisted of copper ingots designed to be re-melted and alloyed with tin to create bronze objects. These axe-ingots are porous, and present many imperfections, and some of them have perforations running through their entire thickness. The aim of the experiment is to recreate the porosity and some of the perforations present on those artefacts.
