This mixing bowl or pudding bowl is unmarked but the person who identified other similar items I have felt it was, the company that took over Medalta Potteries. This piece has a 268 impressed into the bottom. It has no chips or cracks but has a stain about the size of a nickle that goes all the way through the bowl. The bowl is the ideal shape to use for mixing up sauces or scrambled eggs for 1 or 2. Otherwise it is a great accent to a country/vintage kitchen. It is 5½ inches in diameter and 3½ inches high.
