伊朗西部的考古发掘最近发现了来自Sangtarashan考古遗址的重要的Lurkiran青铜器收藏。根据考古研究，该遗址及其青铜器收藏可追溯到伊朗西部铁器时代II/III（公元前10-世纪）。一些金属板容器的合金成分、显微结构和制造技术被确定为揭示伊朗西部公元前一千年的冶金工艺。使用扫描电子显微镜-能量色散X射线光谱和光学显微镜/金相方法进行了实验分析。研究结果使我们得以重建吕勒堡青铜器的制造过程。证明样品是用锡含量可变的二元铜锡合金制造的，这可能与应用非受控程序制造青铜合金（例如共熔或渗碳）有关。拉长的硫化铜夹杂物的存在表明硫化铜矿石可能用于金属生产和冶炼。根据金相研究，使用冷加工和退火循环来成形青铜容器。
Archaeological excavations in western Iran have recently revealed a significant Luristan Bronzes collection from Sangtarashan archaeological site. The site and its bronze collection are dated to Iron Age II/III of western Iran (10th–7th century BC) according to archaeological research. Alloy composition, microstructure and manufacturing technique of some sheet metal vessels are determined to reveal metallurgical processes in western Iran in the first millennium BC. Experimental analyses were carried out using Scanning Electron Microscopy–Energy Dispersive X-ray Spectroscopy and Optical Microscopy/Metallography methods. The results allowed reconstructing the manufacturing process of bronze vessels in Luristan. It proved that the samples have been manufactured with a binary copper–tin alloy with a variable tin content that may relates to the application of an uncontrolled procedure to make bronze alloy (e.g. co-smelting or cementation). The presence of elongated copper sulphide inclusions showed probable use of copper sulphide ores for metal production and smelting. Based on metallographic studies, a cycle of cold working and annealing was used to shape the bronze vessels.
