Shigaraki-yaki Rice Bowls - Pair Set - 2 Bowls These bowls are made using coarse clay, resulting in many "ishi-haze" (stone bursts), which is a characteristic of Shigaraki-yaki. This is not a defect. The glaze is applied by hand, so the application is not uniform. During firing, the temperature varies depending on the location in the kiln, resulting in variations in the firing. I think it's interesting that each one is different. Please understand that these are items stored at home before considering a purchase. Please refrain from purchasing if you are overly concerned about minor imperfections. Thank you for looking.
