This mixing bowl or pudding bowl is unmarked but the person who identified other similar items felt it was Hycroft, the company that took over Medalta Potteries. This piece has a 270 impressed into the bottom. It has no chips but has one major crack down the length of the inside and another crack in the bottom. This bowl is still usable with care. Otherwise it is a great accent to a country/vintage kitchen. It is 6½ inches in diameter and 4½ inches high.
