Why is my candle flame black?

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.

Why do candles flicker when there is no wind?

However, there are two main reasons why candles flicker even when there is no wind! The wick is too long. There are impurities in the candle wax. Thereof, why does my candle smell like smoke? My candle is smokin. 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. The result of this incomplete combustion is sooty carbon, as opposed to typical water and carbon dioxide.

Then, why do candle flames move?

When a candle burns, the flame heats the nearby air and starts to rise. As this warm air moves up, cooler air and oxygen rush in at the bottom of the flame to replace it. This creates a continual cycle of upward moving air around the flame (a convection current), which gives the flame its elongated or teardrop shape. Also, do candles move to music? Doing that over a candle flame, with just the right pressure to not snuff it out immediately, makes a distinct sound. This is the result of fluctuations in the shape and pressure of gasses in and around the candle as they interact with the air you're moving around and through it.

Why do flames jump?

After letting the candle burn for a minute, Simon blows the flame out so that the smoke continues to rise above it. Then when a match is placed near the wick, the flame appears to jump to the candle to re-light it. This is due to the inefficient combustion of wax which causes the smoke to be full of wax residue.
