Well B.I, there is one who will know, and that is Ann. She excavated in Marv/Merv where they found ovens and crucibles, so here they made it – at least the ingots. If you follow the Silk Road, you are likely to find other places where they worked iron/steel, but it would be safer to ask Ann about this, as she has read books, new as old, which I have never even heard about – but I am still looking.
