Iron Chef cookware is produced using a new proprietary casting technology that enables the production of lightweight, thin walled cast iron cookware. The casting is not as brittle as conventional cast iron and can be cast into thicknesses that are less than half as thick. Each piece weighs about half as much as its traditional counterpart. The key benefits of cast iron cookware are heat distribution, good temperature control and good heat retention without the uncomfortable excess weight. This 14 Inch Wok is a good choice for preparing Asian stir fry dishes.
