Iron in Ancient India c7.s5.t1.25

c7.s5.t1.25

Qualitative analysis¹ showed the presence of a small quantity of soluble salt mostly potassium phosphate, siliceous matter and iron. There was no carbon (as we expected), nor any aluminium. The "one-puta," "ten-puta" and "seventy-eight-puta" "lauhas" are the products of heating the same sample of iron. The "hundred-puta" and "thousand-puta" "lauhas," both marked (A), are again the oxidation products of another sample of iron. Lastly, the "thousand-puta" "lauha," marked (B), is a different preparation.
