The tea ceremony teacher is letting go of this item due to their advanced age. The box it was stored in is labeled "Hakuji Shinogi" (white porcelain with ridged design), but it may have been used as a mizusashi (water pitcher) by repurposing another vessel. It looks like a large cocotte dish. The teacher doesn't remember using it. ＜Size＞ Diameter: Approximately 23cm Height: Approximately 8.5cm No replacement lid No box
