To burn, hold a lit match or a lighter flame to the incense for ten seconds or more, then remove the flame. The incense will generally extinguish on its own and begin to slowly burn, but if it continues to flame, you can simply blow it out and it should proceed to smolder. It is important to have a good burner, not only to catch ash, but to make sure that you don't start a fire. It helps to put a small amount of sand, ash, or dry grain, such as rice, at the bottom of cone burners. This improves the air flow under the cone, helping it to burn, and protects the burner from heat.
