This molten blast furnace slag is poured into a granulator and is rapidly quenched through high-pressure water jets, to produce granular particles. This granulated slag is known as granulated blast-furnace slag ("GBFS"). GBFS then undergoes water quenching in a controlled environment to prevent crystalline formation.
