This is a copper alloy skillet, a type of saucepan which stood on three legs. It would be used for cooking on an open fire. At the end of the handle is a perforation. The entire body of the skillet would have been made using the same single outer mould.
Cooking vessels such as skillets can provide some idea about how wealthy a household was, as wealthier households would be more likely to have more than one, in varying sizes. As they were considered valuable, a household would often pass such vessels down over several generations, repairing any holes rather than buying new ones.
