A brazier was a type of heater.
In 2374, Sirella criticized Jadzia Dax because, among other things, "the placement of the braziers on their pedestals is sloppy." Jadzia replied that they were heavy, to which Sirella noted that a Klingon woman wouldn't complain. Dax then said that a Klingon woman wouldn't have to repeat the ceremonial act three times. Sirella then explained that a Klingon woman would have gotten it right the first time. (DS9: "You Are Cordially Invited")
