This clean-burning charcoal from Japan is perfect for burning loose incense and resins. They are made from Hinoki wood and do not contain saltpeter, allowing the beauty 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.
