v1.c28.s3.7

D.P. Agrawal (1982: 234-35) recorded that the Harappans made the vessels in two parts, the bottom and the top, and then joined them. For vessel fabrication they used sinking, raising and lapping, and for joining metal, running on and rivetting techniques. Soldering was used only for noble metals. Metallographic examination showed that the Harappans resorted to open and closed casting, slow cooling of casting, annealing, and cold work. Small animal and female figurines were cast by the cire perdue or lost wax process.
