This is a set of three tenmoku (teacup) plates designed by Masatoshi Saeki, a ceramic artist selected as one of "10 Designers of the World" by the International Museum of Ceramic Art in Faenza, Italy, who passed away in 2019. These are vintage pieces from the late 1970s, no longer in production. 【Size】 Diameter: Approximately 13.5cm (approximately 19.5cm including the handle) Height: Approximately 4cm ※Tenmoku A general term for tenmoku-shaped bowls and ceramic ware with a black glaze. It is said to have originated when monks who studied at Zen temples on Mount Tianmu in Zhejiang Province, China, brought back black-glazed tea bowls when they returned to Japan during the Kamakura period. Later, these bowl shapes were called tenmoku chawan (tea bowls) and tenmoku-gata (tenmoku shape), regardless of the glaze, and black-glazed items were called tenmoku, and black glaze was called tenmoku glaze, regardless of the shape. These items were stored for a long time at my parents' house, but they are unused. They have been stored in a dark place, so there are no noticeable stains or dirt, but please understand that these are vintage items before purchasing. If you are looking for perfect, modern products, please refrain from purchasing. We look forward to your purchase.
