Hello guys,
I have absolutely no knowledge of the fascinating science of metallurgy. I do however am a student in history. Im more particularily trying to establish the authenticity of an ancient story in which there is mention of a large wall made of iron and copper.
The building of that ancient wall, it is said, was done in sections by firstly building a giant mould in the desired location, inside which smaller moulds would be placed;
Firstly, molted iron is extracted from a blast furnace, then poured in the smaller sections, second and while iron is still hot (probably close to melting point), molted copper is poured on top after which the smaller mould is removed and the process repeated, until finally creating a wall, made of merged iron blocks, that were copper coated to provide better protection against corrosion.
The description might seem very primitive or incomplete, what i need to know is whether it is possible for a metal wall to be assembled using that method (or something technically close to it) and also another crucial point; is it possible or would it have been possible for ancient people to copper coat iron by pouring molten copper over very hot iron blocks?
Thanks!
