Purchased at a Shigaraki artist market. I loved using it, but it chipped, so I repaired it. I used kanatsugi bond for the repair, so it can still be used without the chip spreading. The following is a product description: [Product Description] This is a large bowl, 21cm in diameter, with a beautiful black and white contrast, featuring a "black rust glaze split." It has a moist texture like metal, with a "black rust" color close to dark brown, and a clean white color mixed with titanium, creating a two-tone effect. It's recommended as a serving bowl for side dishes for 3-4 people, or for somen noodles in the coming season. The matte and smooth feel of the "black rust glaze" is also pleasant. The white part on the inside varies from bluish white to yellowish white depending on the glaze's density and the firing conditions. Some pieces may have a burnt-like appearance. Please understand this as a characteristic of the glaze and enjoy each unique encounter. Also, the "black rust glaze" vessels will change over time, developing a glossy texture. We hope you will enjoy the aging process and use it for a long time. The artist's mark "hiro" by Hiroaki Kato is engraved on the back.
