Antique Nippon Moriage Plate Bowl Slipware

Nippon Moriage Floral Bowl Blue Purple Green Unmarked 9.5" diameter. Handpainted dish with lid decorated with stylized flowers using wet clay. This is also known as slip ware. Nippon moriage is typical of the 19th century. Unmarked pieces are commonly seen in some moriage dishes. It appears that the paint is intact although some of the slipware has come off. There is a hairline crack in the back of the dish that runs across the middle of the plate. I do not see the hairline crack when I turn it
