Well-dated and preserved medieval bombards are rare and, most of the time, only exist in single exemplar. They are nevertheless exceptional testimonies of the medieval metallurgical skills. The musée de l’Armée (Paris), owns six impressive powder chambers, found in the same place (Meaux, France) and dated from the same period (15th c.). For the first time, this unique set has been studied by classical metallographic investigation, and recent approaches on slag inclusions using SEM-EDS and LA-ICP-MS analyses. The analyses permit to discuss the nature of the metal as well as the process used to obtain the metal (bloomery or finery) but also to consider the diversity of provenances for the metal that was used. These results suggest that five bombards may have been forged in the same area and possibly even in the same workshop, but anyway using metal produced through the bloomery process.

年代久远且保存完好的中世纪轰炸很少见，而且在大多数情况下，仅存在于单一范例中。尽管如此，它们仍然是中世纪冶金技术的杰出见证。Musée de l'Armée（巴黎）拥有六个令人印象深刻的火药室，位于同一地点（法国莫城），年代可追溯至同一时期（15 世纪）。首次通过经典金相研究和最近使用 SEM-EDS 和 LA-ICP-MS 分析的夹渣方法研究了这一独特的集合。分析允许讨论金属的性质以及用于获取金属的过程（开花或精制），但也考虑所用金属的来源的多样性。这些结果表明，五枚炮弹可能是在同一地区甚至可能在同一车间锻造的，
