摘 要:Ancient casting process for production of brass or bronze utensils and icons were made in hot molds using clay molded investment casting or piece mold process,as presumed by *** mold process is still traditionally practiced in many parts of Eastern India and Bangladesh along with investment casting ***,Bengal artisans are more accustomed to piece mold process unlike tribal artisans who practiced investment casting *** piece mold casting process has been reconstructed to get the idea of metal characteristics in order to investigate ancient casting process of Bengal and *** characterization of ancient archaeo-metal products come to a type of cast Cu-Sn-Zn-Pb type quaternary alloy produced by a slow freezing *** these alloys physically differ from the traditional cast alloy of binary Cu-Zn type brass,the physical characteristics are similar to the binary cast alloy *** investigation throws light on the similarity of the production processes by which ancient artisans probably produced cast metal products.
