Mason's Patent Ironstone China shallow dish that I believe will date to the mid 19th Century. Oriental pattern with bright cobalt blue. Approximately 10.5" diameter and 2" deep. A couple of nibbles to one side that appear to have been glazed over white. A firing defect or similar to the main of the dish that reveals stone / buff colour. Minor nibbling to foot. Generally good as far as the finish goes. Please see all photos for assessment / appraisal. Not bad for a plate that will be about 170 years old.
