This is a Gense stainless steel bowl. It might be part of something else, like a double boiler. It is small and shallow so I think it could be the inner part. Not sure. But can be used alone. Measures 8 1/4 from handle to handle and 6 1/2 from side to side. Is only 1 3/4 inches deep. Heavy grade stainless steel, well made. Has stir marks inside from use but no gouged or anything.
