Iron in Ancient India c3.3

c3.3

I believe that the theory of forging small blooms of wrought iron into entire beams and pillars is the real solution of the question how these beams and pillars could have been forged with hand labour. As regards the solution of the problem how these pillars have so long withstood the rusting influence of wind and rain, my idea is that " low manganese with low sulphur and high phosphorus " in the composition of the iron has something to do with the " corrosion-resistance " capacity of wrought iron. I also suspect that the pillars and beams were originally painted.
