- Place the cookware back in the oven, and bake for another two hours.
How to Re-Season Cast Iron Cookware
Before using cast iron cookware for the first time, it must be seasoned. Seasoning prevents rust and creates a natural non-stick surface. If the surface of your cast iron pot or pan has become damaged, you can re-season it, and it will be good as new again. With proper care, cast iron cookware can be used for many decades and passed down from one generation to the next.
