Nine porcelain lidded tea bowls. The surface is fired with a mottled peach color, but no overglaze enamel decoration is applied. It is reminiscent of the Chinese Qing dynasty's ten-brocade hand-painted famille rose peach-glazed tea bowls. The inside of the bowl and the rim on the underside of the lid feature underglaze blue (sometsuke, or "seika" in the original Chinese style) with navy blue patterns. The bottom of the bowls depicts lions with various expressions in shades of navy blue. The base bears the backstamp (pottery mark) "Seiho" (清鳳). While it resembles Chinese porcelain, the combination of peach glaze and underglaze blue, as well as the backstamp on the base, doesn't seem Chinese in style. Although a master craftsman of Kyo-yaki (Kiyomizu-yaki) named "Kono Seiho" can be found, the backstamp doesn't match. They were stored in a box, possibly a storage box, with stains and discoloration. The side of the box is labeled "Teshiosara" (small salt dish), and the opposite side reads "Teshiosara, for 20 servings, Hara Taisho?" It's almost impossible to store twenty tea bowls in a box like this, and it's also unlikely to be for "Teshiosara." The box was likely used for storage. "Teshiosara" originally referred to small, shallow dishes used to hold salt for purifying the meal. They are often used in Japanese dining and are also used for serving pickles and other side dishes. The mottled peach-colored lidded tea bowls, the underglaze blue lion design revealed when the lid is opened, and the ordinary backstamp – the combination of these elements gives a sense of intentional creativity and eccentricity. Similar or identical lidded tea bowls have not been found, making them mysterious. These are items stored at home in a temporary storage box. One bowl has a chip and stains (photos 8 and 16), but the others have almost no noticeable stains or damage and can be considered in good condition. I consulted an expert and listened to their insights. The expert suggested that the bowls are likely Kiyomizu-yaki, the underglaze blue rim patterns and lion designs appear to be hand-painted and well-executed, the mark is indeed different from "Kono Seiho," and it doesn't seem to be a "Teshiosara." The last two points were as expected, but the conclusion was that they might be imitations of Chinese porcelain. The potter is unknown, but there is a high possibility that they are old, high-quality Kiyomizu-yaki. Average size (cm) and weight (g): Height (with lid) 6.6, (without lid) 4.8, Diameter 10.5, Foot rim 0.7, Base diameter 4 / Weight 200 (181-211) / Nine lidded tea bowls with mottled peach glaze and underglaze blue lion design. One bowl has some damage, but the others are almost undamaged. The potter and the production period are unknown, but according to the expert, there is a high possibility that they are old, high-quality Kiyomizu-yaki. We hope you will use them as tea bowls and enjoy their eccentric and original design. There are also mysteries, and there may be misunderstandings in the explanation, but this is an assessment of high-quality tea bowls. Please, by all means, solve the mystery.
