This is an antique Victorian white ironstone or stoneware mold used for shaping jellies, puddings, or meat dishes. My mom had a collection of these that I recall from my childhood, and had them as display and decorative pieces in our kitchen. These molds were commonly produced in England during the late 19th century, and were considered essential kitchen tools. This pieces has a minor chip, but beautiful crackle glaze and visible "No. 1" stamp on bottom.
