The addition of carbon to iron, when manipulated with heat makes it hard and strong <--- that's almost alchemy. And there's no chemical reaction. There's not even any molecules. It's simply carbon atoms physically jammed between iron atoms laid out in a metallic crystalline matrix, made possible because of a FCC->BCC flip caused by heat and carbons ability to flow in that crystal.
I learned something new today. Cheers!
The rest of post #169 was interesting. Thanks.
