Sloss Iron
This micrograph reveals the internal structure of Sloss pig iron after etching. While the unetched sample shows graphite shapes, etching exposes large white particles of iron carbide (cementite) within the iron matrix. These carbides indicate a high carbon content and contribute to the material’s hardness and brittleness. The etched image offers deeper insight into the microstructural complexity of historic industrial ironmaking at Sloss Furnaces.
