Enameled cast iron frying pans boast the same durable construction and heat retention as unfinished cast iron, but with a smooth, elegant enamel coating for easier cleanup. These pans are made the exact same way as an enameled cast iron Dutch oven: Molten iron-carbon alloy is poured into a proprietary frying pan mold and then left to cool, before being coated with an enamel made from powdered glass.
