Slag Car

Slag Car. This huge ladle is one of two mounted on a slag car. Slag is a layer of impurities that floats to the top of the molten iron; it was skimmed off to be poured into these cars waiting underneath the casthouse. It was then carted off and dumped into a slag heap, where it was cooled and most likely used for creating cement or ballast.
