What texture is cast iron?

Cast iron typically has a rough, gritty texture due to its crystalline structure and the presence of graphite flakes. This texture can vary depending on the specific type of cast iron, such as gray cast iron, which has a more pronounced roughness, or ductile cast iron, which is smoother. The surface can also be affected by the casting process and any subsequent finishing treatments. Overall, cast iron is known for its durability and ability to retain heat, making it popular for cookware and industrial applications.
