"so where did the heat needed to create the pools of molten steal come from?"

Your ignorance only makes you look stupid.

I also did black smithing - and when steel oxidises (burns) it gets hotter and hotter ... :-) called 'exothermic reaction'... :-) and there were other common chemicals present that catalysed and promoted the oxidising the reaction - and you saw the fire... and buried at the bottom of a pile of junk, it was pretty well insulated... (hint - dry wall among other things)...

If you don't know any Science, then don't make Conspiracy theories out of whole cloth using your ignorance.

All this 'Secret Squirrel Conspiracy' nonsense has been debunked endlessly, here and elsewhere" on the web...

Please go away - you are just embarrassing ...
