What happens when you light smoke on fire?

When you light a candle, the heat from the flame vaporizes the candle wax. When you blow the candle out, vaporized wax briefly remains in the air. Although it looks like you're lighting the candle with smoke, it's really just the wax vapor that ignites. Soot and other debris from the flame aren't ignited.

One may also ask how do you light a fire with smoke?

Can you set smoke on fire? Smoke can be flammable, though it is not always. Smoke is produced by incomplete combustion of the fuel in a fire. This leaves unburnt fuel in the smoke (especially in dark, black smoke) that can ignite when the ideal combination on fuel, heat and oxygen is reached.

Why can you relight a candle using the smoke?

So, how is it possible to relight it through the smoke? The trail of smoke released by the smoldering wick of a candle still has wax that hasn't fully burned. When you hold a fire source to the wisps of smoke, they can reignite and cascade back to relight the candle! What are the 3 things needed for a fire to burn? Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

Keeping this in consideration, why did the smoke ignite while the candle without smoke did not?

Here is his explanation: 1) When you are burning a candle, you are essentially vaporizing the liquid wax into a gas that is flammable. This vapor can then be used as fuel for the candle flame. 3) Therefore, as you hold a flame close to the smoke it will light the unused wax vapor that is in the smoke. Regarding this, can candles relight themselves? As soon as you blow it out, the trail of smoke released by the smoldering wick still contains a bit of wax that hasn't fully burned. When you hold a fire source up to the wisps, they can reignite and cascade back down to relight the candle.
