This is an Oribe-yaki three-legged bowl. It's a large bowl with legs, approximately 17.5cm x 20cm in diameter and 8cm in height. The body is covered with a streaked green glaze, and when you look inside, the unique glaze creates an expression reminiscent of a deep, mysterious cosmic nebula. There is a potter's mark, but it's unreadable, so the artist is unknown.
