The moment of molten metal pouring is always critical. Even though the gestures have hardly changed since the GHM factory's opening in 1857, it takes years of experience to pass this phase. The heat of the incandescent mass can reach 2,553° F (1,400°C), and the workers handling the pouring wheel seem little protected. The factory is renowned worldwide for the high quality and flowability of its cast iron. The statues, fountains, or pieces of street furniture crafted at GHM adorn numerous cities throughout the globe.
