Cast iron collectors now recognize six series of Erie skillets. The number 8 pictured above is a stellar example of the final series. The inset heat ring and beefier handle are two of the characteristics that one finds in later Eries.
Both of these skillets are functional and beautiful antiques that showcase the workmanship found in handmade products from over 100 year ago.
Griswold cast iron went on to become the dominant name in American cast iron until 1957.
