How do I know if my cast iron dutch oven is preseasoned?
You would know if the dutch oven was covered in wax. Cast iron prior to seasoning is a light grey color. It will rust very quickly just from atmospheric moisture, so they cover it in paraffin wax to preserve it. The process of seasoning the utensil forms a tough, yet smooth, black coating of polymerized oil. If your dutch oven is a slightly shiny dark black, it is safe to say that it has already been seasoned. With the proper care your dutch oven will last you many lifetimes-- enjoy it!
