This bamboo charcoal from Japan is perfect for burning loose incense and resins. These are clean-burning and do not contain saltpeter, allowing the sense of the natural incense materials to shine. To light, hold with tongs over a flame until the edges are lit (they will turn white). Then place the charcoal piece on a safe incense burner or a small bowl of ash or sand. Using tongs or a spoon, place your incense materials on top.
