Enameled cast iron has very few downsides, and this is one of them. If you drop or otherwise hit the surface with a heavy object or utensil, the material is prone to scratching, chipping—and in extreme cases, cracking. This is because the enamel coating is made of a material similar to glass. But don't worry.
Enameled cast iron cookware is safe because it is a durable material that does not leach iron, has a naturally non-stick surface, and does not rust. These qualities make it a safe choice as it minimizes the risk of health problems associated with cookware made from other materials.
