This is a pair of yunomi (teacups) from the Gyokusuiken Kokuzo kiln, an Imoyaki kiln in Sado. I am selling them because I have no opportunity to use them. Although they are unused, the box shows some stains due to long-term storage at home. 【Imoyaki】 Imoyaki is made by using Mumei-i, a mineral containing iron oxide that is produced from the Sado gold and silver mines, and firing it at high temperatures. It is characterized by special manufacturing processes such as raw polishing and sand polishing after firing. Among them, the process of adjusting the fine-particle clay called "suihito" carefully removes sand and impurities, allowing for a finer finish and increased durability. The finished product is very hard, and a clear metallic sound can be heard when tapped, which is another major characteristic. The luster gradually increases with use, and the flavor develops over time. - Type: Yunomi (teacups) - Material: Pottery - Color: Red, Brown - Quantity: Set of 2 - Design: Wave pattern, Two-tone color - Accessories: Special box, Instruction manual Thank you for viewing.
