Abstract
This study presents the first comprehensive analysis of a late 17th-century bell foundry workshop excavated within the UNESCO-listed belfry of Saint-Sauveur church in Gembloux (Belgium). Archaeological investigations revealed exceptionally well-preserved structures, including a casting pit, the kiln floor of a smelting furnace, and ash pits, alongside a significant assemblage of artifacts: 29,000 clay mold fragments (core, false-bell and cope moulds), bricks, crucibles, slag, and copper alloy residues. Archaeomagnetic dating places the foundry’s activity between 1669 and 1689 CE, likely following a devastating fire in 1678. At this time, the bell founders from eastern France established temporary workshops near the bell installation sites. Thin-section petrography and EDS (Energy-dispersive X-ray spectroscopy) analyses identified local loess as the primary raw material for moulds and bricks, with lime and sand as well as vegetal, and animal fibres added to the clay moulds for structural enhancement. Preliminary botanical analysis suggests the use of flax, hemp, or nettle fibres in the moulds. Crucibles, however, were crafted from refractory clays imported from the Meuse Valley, indicating external specialized production. This multidisciplinary research provides valuable insights into historical bell-making techniques, raw material sourcing, and the regional network of itinerant artisans, contributing to the conservation and cultural development of this unique heritage site.
期刊介绍:
Journal of Archaeological Science: Reports is aimed at archaeologists and scientists engaged with the application of scientific techniques and methodologies to all areas of archaeology. The journal focuses on the results of the application of scientific methods to archaeological problems and debates. It will provide a forum for reviews and scientific debate of issues in scientific archaeology and their impact in the wider subject. Journal of Archaeological Science: Reports will publish papers of excellent archaeological science, with regional or wider interest. This will include case studies, reviews and short papers where an established scientific technique sheds light on archaeological questions and debates.
