Carolyn, not only are there different sizes, but shapes also. The wheat stick pans, they make corn bread, but with the impression of a head of wheat on them. When you get your books you'll see. Oh, and when you strip a piece down and its grey like we been sayin, it'll flash rust right in front of your eyes. As far as I know there ain't much you can do to stop that. If I am going to season a piece, I just put it in the oven as you have already talked about, and then when you put your seasoning, whatever you use, lard, crisco, whatever, the flash rust will go away. Hope we are helping you and not confusing you. We don't want to burn you out. But this stuff does get habit forming. Wait till you get the book, it is very interesting. I find that the cast iron companies were very good at marketing, changing things, different sizes, shapes, different items, whatever to keep sales, all of the variations of all the items is mind boggling, at least to me it is, but you gotta just concentrate on what you like and go from there, when you get comfortable with that, if you wanna expand thats fine, for instance, you have been talking about these corn bread pans, you'll see that there are different variations, several in fact, not only in size but the shape. When you get the book I am sure you will have more questions.
