I'm from The UK where I believe the modern smelting process for Iron was formulated at some point in the 1700's. We have the best iron, just beautiful, 300 year old iron😜. Clearly a Trump piss-take and I don't have any iron that old but I am from The UK. There is a place over here called "Ironbridge", where, funnily enough. The world's first bridge, made of iron, was built😁.
