Steel is at the core of many cookware lines. It is comparable to solid cast-iron due to its raw finish but is lighter, unbreakable and won’t chip, and will not retain odors. An alloy of iron and carbon, it is hard, durable and warp-resistant, and is impervious to metal objects, such as knives, forks and spatulas. Steel pans comply with demanding professional requirements, such as long pre-heating times, high-heat levels and intensive use, and are thermal shock-resistant and compatible with all heat sources, including induction. Commonly called "carbon steel", they come with different finishes including silver if intensely polished, or a blue or black finish from a heat treatment process which protects temporarily against oxidation. The Paderno World Cuisine 10 1/4-inch crepe pan is constructed of high-quality, polished carbon steel and is cooktop, oven and broiler-safe. The thickness of the steel, 1/8", allows for longer pre-heating which results in a hotter surface that quickly cooks and singes crepes. After an initial seasoning and continued use, the carbon steel pan will lose its initial sheen, but acquires a natural non-stick surface that won't chip, scratch or peel off. To maintain the finish and avoid oxidation, wash the pan in hot water, then wipe dry with a paper towel. It may then be oiled and stored in a dry place. Most chef dry their steel pans by putting them in a low temperature oven for a few minutes.
