Bizen-yaki Master Tatsuhiko Kozaki Rakugan Kiln Reduced Firing Natural Ash Glaze Beautiful Round Jar Flower Vase Size: Rim diameter 14mm, Total height 230mm, Depth 210mm, Base diameter 125mm. Comes with a wooden box, cloth, and a descriptive card. Bizen-yaki is a pottery that inherits the tradition of Sueki ware and is extremely simple, using no glaze (the chemicals applied to the surface of unglazed pottery) and no painting. Using special clay from the Bizen region that is over 1.5 million years old as a raw material, it is fired at a high temperature of over 1300 degrees Celsius for approximately 10 days and nights. The beauty of the reduced kiln-changed natural ash glaze patterns is created by the nature of the clay, how the kiln is packed, changes in the kiln temperature, and ash and charcoal during firing. The handmade depth of flavor is attractive, as no two pieces have the same color or pattern, and the flavor increases the more they are used.
