The pottery of this style made in that period is called Mino-Momoyama ware. Production of porcelain, which is much harder, whiter and more durable than pottery, began in Kyushu in the beginning of the Edo period. Pottery used to reflect the taste of tea masters as tea ceremony grew in popularity. In Toki City, porcelain production began in the last days of the Edo period. Ever since then, Toki City has been a centre for production of pottery and porcelain, being supported by techniques and craftsmanship established over a long span of time. Mino- yaki ware has now a 50% share of the pottery market currently in Japan. How do you care for Mino-yaki ware. Please remember that potteries are in fact more fragile than porcelains. Do not use the microwave, oven or dishwasher. Washing it by hand is best. Cold or hot water with a mild soap is great. Please dry well. Do not soak the pottery. It can get mouldy. If the product has stains, use kitchen bleach.
