Arita porcelain dish, Japan late 17th century

Large Japanese porcelain dish, Arita kiln, compartmentalized decoration inspired by Chinese models from the end of the Ming dynasty. In the center a flowered basket and on the edge, cartouches containing flowers and emblems are boldly drawn in underglaze cobalt blue. The reverse left without decoration. The firing was perfect, the blue is bright, the glass is uniform.
There is a big chip. Curiously this flake is covered with glassure which means that it was made between the first firing of the clay (1000°) and the final firing of the glassure (1250°). In the 17th century it was difficult to fire large dishes without them becoming more or less deformed during drying or the first firing, as the shape of his dish was perfect, the potter finished his work despite the large chip .
Japanese work from the second half of the 17th century, fired in the Arita ovens. Made for export.
Diameter 413 to 418mm.
We can consider that this defect depreciates the object, however if this dish had not had this rare curious and touching defect, I would not have included it in my collections.
