As described in 1909, the chimney of the foundry extended upwards along the slope of the mountain:
“The furnace fumes are drawn out by a wide elbow pipe, communicating with a very large balloon-shaped pipe that serves as the first dust deposit chamber; follows the large dust chamber, and to this is attached the inclined shaft along the mountain slope for a height of 86 meters, after which a section of well 25 meters of vertical iron chimney rises. This arrangement allows for an abundant draft, and moreover, the end of the chimney being well detached from the surrounding ground is well caught by air currents, which facilitates the dispersion of sulfur fumes.”
