Since 1925, Le Creuset's premium cookware has been fashioned in France from porcelain enamel cast iron, giving it a durable weight and a beautiful finish. 

The benefits to this cookware's construction are many:

Cast iron distributes heat evenly and requires cooking with only low to medium temperatures. Cookware is for use with gas, electric, induction, or ceramic ranges. Flat cookware bottoms sit firmly on heat surface. Thin shell casings are light but strong. Porcelain enamel coating is easy to clean and won't absorb odors or flavors. Lids seal in moisture and flavor. Knobs are heatproof up to 450 degrees F.
