Most of my cast cooking pots/pans came from my parents and there parents and from them I really don't know how far back. I make corn bread and fry potaters in the pans and cook fish in the smaller pots and make gumbos and stews in the larger pots (5-10gallon). I have what we call chicken fryers (large deep fry pans). I have looked and there are markings on the bottom of most of them but I can't make anything of them. I do know they do cook good.
