But you have to take good care of your cast iron cookware for it to last.  Before using it for the first time, you have to season your cookware.  This is a process where oil is absorbed into the pores of the cookware that will leave a black, nonstick surface.  Just follow the instructions properly because you will need to re-season your cookware whenever it needs it.  And you can use your cast iron cookware for a long, long time.
