To light the charcoal, hold it by one edge while applying flame to the other. (The safest way to do this is to use incense tongs.) Self-lighting charcoal will begin to crackle and pop as the surface ignites. (You can blow on it gently as if you were lighting a campfire.) When the whole surface is glowing, it's ready for you to add your incense. Add incense a pinch at a time, and enjoy!
