The iron piece was repeatedly forged to separate maximum possible quantity of the slag and convert the spongy mass into a solid rod of 15 mm dia x 150 mm length. This refined bar was classified into various categories on the basis of its ductility and appearance of the fracture. This standard refined wrought iron bar was sold to blacksmiths (Lohar) or steel makers for further refining and fabrication of various war weapons and agricultural implements etc. An assessment of the metallurgical properties of the iron produced by the Bishunpur craftsmen has already been published by Prasad K.K. et al. (1990)
