I believe this is Karatsu-yaki pottery. It belonged to my grandmother, who had connections with the kiln. Karatsu-yaki is characterized by its rough, rustic texture, various decorative techniques such as iron painting, hakeme (brushstroke), and Madara-Karatsu, and the "beauty of use" that increases in character the more it is used. The natural expression that avoids artifice, the traces of fingers, and the marks of the foot ring, the spirit of "wabi-sabi" that finds beauty in imperfection, are also charms of Karatsu-yaki. ① Size: Diameter 128mm, Height 77mm ② Size: Diameter 120mm, Height 79mm ③ Size: Diameter 117mm, Height 70mm ④ Size: Diameter 127mm, Height 97mm ⑤ Size: Diameter 120mm, Height 85mm Please allow for some error. ① There is a small area on the outside of the black where the color is missing. It doesn't appear to be a scratch, but rather that the color hasn't been applied. Please check the fourth photo. ② There is a slight snagging feeling around the rim. Is this also related to the application of the green color? ③ There is the character "明" (light/bright) on the back. ④ This is the largest of these. ⑤ It feels smoother to the touch than it looks. I don't have any knowledge, so I apologize if I've written anything inaccurate. I can't use these, so I hope someone else can.
