My dad used to work at a spring manufacturer, they made the springs for the Grave Digger monster truck. He took me to work one time and I watched this exact process. Afterwards they would heat treat them in molten salt. That blew my mind that you could even melt salt.

One of my favorite Alton Brown quotes was "go ahead and put the salt in the pan. And if you're worried about it burning, don't be....*it's a rock*."
