Watch the Magic of Metal Chain-Making

Oh, so that’s how it works.

This is not a task you’d want to tackle by hand. 

Metal chain-making requires intense heat and intense pressure. There is a reason those chains are so hard to break. This machine heats and bends red-hot rods of metal, smoothy linking each piece to the previous one. As the metal loops cool they fade from glowing crimson to glistening silver, clustering into a pile beneath the machine.

Now you need never again look at the chain lock on a door and wonder, “How was that made?”
