Lodge is electrostatically coated with a proprietary vegetable oil and cured at high temperatures to allow the oil to deeply penetrate the surface of the cast-iron. Natural sand mold surface is ideal for our new, seasoned, ready-to-use finish. Sturdy, integral, ovenproof handle and assist handle provide lifelong durability. Tightly controlled metal chemistry and exacting mold tolerances deliver consistent product for even heating and superior cooking performance.
