In case you do not know, Granulated Blast Furnace Slag is the by-product produced during the process when iron is obtained from its ore. When iron ore melts inside the blast furnace along with lime stone and coke, molten slag is formed floating above the molten iron. The temperature of the slag is somewhere between 1500 and 1600 degree Celsius.
