What kama means
The kama is the iron kettle in which water is heated for the entire tea gathering. It sits on a ro hearth set into the floor in winter and on a furo brazier in warmer months, a seasonal switch observed by Urasenke and Omotesenke. The sound of water beginning to simmer in the kama, called matsukaze or wind in the pines, is itself part of the atmosphere of chanoyu. Most kama are cast in regions such as Ashiya and Tenmyo and are valued for both their tone and their patina.
