A Karatsu ware jar fired in the Shiinomine kiln in the 1650s to 60s. It forms a plump body with a short neck and the whole body covered with ash glaze on the base clay. The copper-green glaze applied to the upper body shows a vivid blue and ruby red colour. Although it is rare, such mesmerising colour of kiln alteration can be seen in some of Karatsu ware examples, and the influence of Jun ware has been pointed out. A stack mark on the brilliant turquoise blue skin creates a highlight.

There are chips on the base, but there are no other noticeable defects, and the condition is good. Come with a box.
