The 108 ingots found in Sirkap came from the first century AD layer. These are hexagonal, long torpedo-shaped and shuttle-shaped pieces measuring between 4.75 and 7.12 inch in length and 1.3 to 2.5 inch in width at the middle. (Similar blooms were used for forging the iron beams at Koṇārka, several centuries later). The ingots weighed 1-1/2 to 4 lbs. and assayed in terms of elemental percentages: 0.1 C, 0.03 Si, 0.019 S, 0.077 P, trace Mn and 99.6 Fe.
