Dōan-buro (道安風炉, way-peace wind-hearth), or open-style brazier, designed for use with a tetsubin pot and, in some cases, traditional kama.
This style of furo is attributed to Sen Dōan (1546–1607), eldest son of the legendary tea master Sen no Rikyū, and emerged during the Sengoku Period (1477–1573) as part of the evolution of Japanese tea aesthetics.
Though it bears a bronze-like appearance, the brazier is cast from ‘karakane’, a copper alloy of copper, lead, and tin. It is accompanied by an iron gotoku stand and a ceramic maekawarake, which protects the surroundings from heat and sparks. The heating element is embedded in a ceramic charcoal shaped like a chrysanthemum (kikusumi).
