Since 1851, BK is the royal founder of the dutch oven and known throughout at the world for a heritage of innovation. Black steel is three times denser than aluminum, corrosion and stain resistant, as well as stronger and more durable than traditional grey carbon steel. Pre-seasoned with oil, this pan ships with a thin silicone wax coating that's much easier to remove than a thick layer of beeswax or grease, so it's ready to use after a quick wash with soap. Designed to develop a natural nonstick patina layer, this is a pan for life. The more you use it, the better and more nonstick it gets. The heat-responsive design means you get the same great searing results as cast iron without the hassle. Metal utensil safe, oven safe up to 600f riveted cast iron handle suitable for all stovetops including induction, two-year limited warranty hand wash only, dry completely before storing. Crafted from pre-seasoned carbon steel, this ready-to-go wok is your go-to for incredible stir fry and searing. Tough and lightweight and specially designed to develop a patina layer over time, which makes them naturally nonstick. Sturdy cast iron handles.
