Why Your Candle Flame is Moving So Much (4 Reasons Why)

Have you ever noticed that when you blow out a candle, the flame doesn’t stay put? It instead dances around and sometimes even crawls up the wick again. You might have wondered why this happens, and what is making the flame move.

Well, today we’re going to explore the science behind this dancing fire and find out what’s really going on. Stay tuned!

Why Is My Candle Flame Moving So Much?

Your candle flame is moving so much due to convection and turbulence, movement of air, the wick, and soot.

When you light a candle, the flame is fuelled by a small wick. The heat from the burning wax melts the wax near the wick. This liquid wax is drawn up the wick by capillary action.

The heat of the flame vaporizes any liquid wax drawn up the wick, which then recondenses on the part of the wick closest to the flame.

This liquid wax then diffuses the heat of the flame, which vaporizes it and starts the process over again. The constant supply of liquid wax means that the flame can keep burning for a long time.

1. Convection and Turbulence

The movement of a candle flame is caused by a combination of convection and turbulence. Heat rises from the hot wax near the wick, causing a flow of hot gas upwards. This flow disturbs the flame, making it flicker.

2. Movement of Air

The movement of air around the room can also affect the candle flame, causing it to bend and wave. All these factors combine to create the fascinating dance of a candle flame. To prevent this movement, make sure you light your candle away from open windows, fans, air vents, or any other areas in your house with a large supply of air.

3. Wick Size

The size of the wick also affects how much the flame will move. A thicker wick will produce a steadier flame, while a thinner wick will create a flame that flickers more. This is because a thicker wick can hold more liquid wax, which diffuses the heat of the flame better and prevents the formation of hot spots.

4. Soot

Soot is another factor that can affect the movement of a candle flame. Soot is created when the candle isn’t burning properly. This can happen if the wick is too big, there’s not enough oxygen, or the wax is of poor quality. Soot can build up on the inside of the glass jar and make the flame flicker more.

As you can see, there are lots of factors that affect the movement of a candle flame. So next time you’re lighting a candle, remember all these factors!

How to Stop a Candle Flame From Moving So Much?

If you want to stop your candle flame from moving so much, there are a few things you can do.

Make sure you’re lighting your candle in a draught-free area. If there’s a breeze in the room, the flame will flicker more.

Trim the wick to about 1/4 inch before you light the candle. A shorter wick will create a steadier flame.

Use a thicker wick. A thicker wick can hold more liquid wax, which diffuses the heat of the flame better and prevents the formation of hot spots.

Make sure the room is well-ventilated. If there’s not enough oxygen, the flame will flicker more.

Use a high-quality wax. If the wax is of poor quality, it will produce more soot and make the flame flicker more. I recommend using a beeswax or soy wax candle because they burn cleaner and produce less soot.

Follow these tips and you’ll be sure to have a steadier candle flame!
