Here is a very beautiful 19th Century Japanese Imari plate. Please browse the photos. They are most of the description.
There are two tiny edge frits, pictured in photos 6,7, & 8. They are barely visible (at the back of the edge, under 1/8” and age darkened), and where they do show, they only add to its beauty. There are no other hairlines or cracks.
Plate diameter: 8 1/2”
Foot diameter: 5”
Foot is slightly over 1/2” high; overall height is 1 1/2"
