The analytical figures show that as in the Delhi pillar, in Koṇārka samples also, the carbon percentage is not negligible. Percentages of Mn, S (as well as P) are low. There is some silicon; the percentages are variable, presumably because forge-welding was done on smaller pieces obtained from diverse source. Micro-structure and hardness values at different regions of the Koṇārka sample were noted by Ghosh (1963: 37), and a summary thereof is reproduced in Table 19.5.
