An apparatus and method for quick quenching liquid slag, which includes a bay area for receiving the liquid slag and a water supply system for spraying, or quick quenching, the liquid slag provided on the bay area with water to cool the liquid slag and turn it into a crystalline form. The bay area includes an angled and generally flat surface provided between first and second ends, with the first end defining a high end and the second end defining a low end, such that liquid slag provided to the bay area adjacent the first end will run down the bay area toward the second end. The water supply system is provided operatively above the bay area and applies water to the liquid slag on the bay area such that the liquid slag cools and turns into a crystalline form. Additional amounts of liquid slag may be poured on top of previous cooled and quenched crystalline slag and quick quenched with water in a similar manner.
