Why can you light a candle by lighting the smoke?

The process becomes self-sustaining. 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 happened to the candle when it was lighted?

When you light the wick, the flame causes some of the wax to melt, flow up the wick and evaporate, and then the wax vapor burns. Wax is made of hydrogen and carbon. When a candle burns, the hydrogen and carbon from the wax combine with the oxygen in the air to become carbon dioxide and water vapor. Consequently, why is there black smoke coming from my candle? The candle has been burning for too long. Once the surface is liquid, the inner wax of the candle heats up and begins to evaporate very quickly. The candle is then unstable, causing the flame to burn irregularly. The more the flame moves, the more likely it is to give off soot.

Correspondingly, why do some candles smoke?

Smoke is created when the flame of the candle is unable to properly burn all the fuel (in the form of vaporized wax) efficiently due to a lack of oxygen. Because the wick is drawing oil from the candle wax, a buildup of oils can occur within the wick when the flame fails to burn as much oil as it's taking in. Consequently, why can't you burn candles for more than 4 hours? If you burn your candle for more than 4 hours at a time, carbon will collect on the wick, and your wick will begin to "mushroom." This can cause the wick to become unstable, the flame to get too large, your candle to smoke, and soot to be released into the air and around your candle container.

Accordingly, when should you stop burning a candle?

As with most things, knowing when to stop burning your candle is important. This keeps you, and your furniture, safe. When there is approximately 1/2" of wax left in the bottom of your candle it's time to stop burning. It's okay for there to be some wax left over, candles are created with this little buffer of wax. And another question, how do you stop a sinkhole from making candles?

How do you stop a candle from bubbling?

The single best way to avoid getting air bubbles in your glass jar candles is to make sure to pre-heat your glass jars to about 160 degrees before pouring your candle wax into them.
