To prevent rusting: we enamel our cast iron. Traditional cast iron is prone to rust. You have to be diligent about thoroughly drying and seasoning your pieces to keep them in good shape. That’s why we designed our cast iron pieces with a layer of enamel (glass) to protect the cast iron. No seasoning required.
