A different kind of incense, these pieces come in the form of tiny bricks and emit a smokier, fiery smell which brings to memory the warm cozy ambiance of a burning fireplace or wood-burning stove. Each brick (cone) lasts about 20 minutes and leaves a pleasant after-scent. Some use candles to light the bricks and set into the appropriate burner. Small bricks measure approx. 1.25 x 0.25 x 0.25 inches.
