Read the entire article and seems credible, though it was never explained how the acid was made. Then at the bottom was this: "New Analysis Proves Most If Not All Bronze Age Iron Came From Space." That blew everything up.

I think “Most If Not All Bronze Age Iron Came From Space” means the iron of that period came from meteoric sources, which are nearly pure iron, rather than be being mined as ore and smelted.
It looks more sensational than it is.
