Making Pig-Iron

About this artwork

Joseph Pennell's *Making Pig-Iron*1916) is a striking lithograph that captures the raw intensity of early 20th American industry. As a master printmaker, Pennell was renowned for dynamic depictions of modern machinery and labor, often infusing them with a sense of awe at technological progress. This work, part of the National Gallery of Art's Rosenwald Collection showcases molten iron being cast into ingots—known as pig-iron—in a blast furnace, highlighting the grueling yet transformative process central to steel production. Created amid World War I's industrial boom, the lithograph reflects America's surging role as an arsenal of democracy, where ironworks fueled everything from ships to weapons. Pennell's realist style, rooted in the printmaking revival, romanticizes the inferno-like glow and hulking forms, evoking both peril and power. Lithography's versatility allowed Pennell to achieve rich tonal contrasts and smoky atmospheres on a flat stone surface, making this print an accessible yet vivid window into an era's economic might. A testament to his over 900 lithographs, it invites viewers to marvel at the human hand behind mechanical marvels.
