Sometimes one would like to stop a burning incense stick after a while, before it is completely consumed. If you don't want to keep around it to, for example, put it under water, you can always break it in short pieces. However this can make it more difficult to hold them or to completely burn them afterwards. What are other alternatives to time-out the parfume?
One simple alternative is to put a small wire coil around the stick at the point you want it to stop. This will make the heat dissipate and will lower the coal temperature, preventing the combustion to continue and finishing the process.
The picture shows a coil ready for the next short combustion. A tight single loop would suffice.
To stop an incense stick before it has burned to its end so that it can be relit when desired:
Reusable Hack: Fold a piece of aluminum foil a few times into a strip and bend that in half over the glowing end of the glowing tip of the incense for a while.
Two things will extinguish the material: the foil will remove oxygen to snuff the oxidation and the foil will absorb the heat from the ember.
