A candle flame that is too high can be visually striking, but it can also be a safety hazard. A tall flame can indicate that your candle is burning too hot, causing the wax to melt faster than it can be burned and leading to a shorter lifespan for your candle. It can also increase the risk of accidental fires, especially if placed near flammable objects. To identify if your candle flame is too high, look out for signs such as erratic size, excessive flickering, or smoking. If you notice these issues, it is recommended to extinguish the flame, let the candle cool, and trim the wick to control the flame's height. The ideal flame size for smaller candles is typically between 1/2 to 1 inch, while pillar and large taper candles can reach up to 2 inches without causing concern.

What You'll Learn
A candle flame that is too big can be a fire hazard
To prevent this, it is important to trim the wick of your candle regularly. The wick plays a crucial role in determining the height of the flame. When a candle is lit, the wick absorbs the melted wax and pulls it upwards towards the flame through capillary action. If the wick is too long, it can draw up more wax, resulting in a larger flame. By trimming the wick to around 1/4 inch, you can control the amount of wax being burned and maintain a steady, healthy flame.
Additionally, it is recommended to keep candles away from drafty areas. Drafts can cause the flame to rise higher as it works more vigorously to stay lit. Vibrations from air conditioners, ceiling fans, or even the ground can also cause the flame to flicker and rise higher than normal. Placing candles on solid surfaces, such as stone or glass, can help them burn more steadily.
It is also important to avoid burning candles for extended periods. If a candle is left burning for more than four hours at a time, carbon will collect on the wick, causing it to "mushroom." This can lead to an unstable wick, a larger flame, and increased soot and smoke release. Therefore, it is advisable to burn candles for shorter durations and always ensure they are extinguished before leaving them unattended.

The wick might be too long, causing the wax to melt faster
If your candle flame is too big, it might be burning too hot, causing the wax to melt faster than it can be burned. This is likely due to the wick being too long, which allows more wax to be drawn up, resulting in a larger flame.
The wick plays a crucial role in determining the height of the candle flame. When a candle is lit, the wick absorbs the melted wax and pulls it upwards through capillary action, providing fuel for the flame. A longer wick results in a larger flame because it allows more wax to be drawn up. Conversely, a shorter wick limits the amount of wax that can be absorbed, resulting in a smaller flame. Therefore, keeping the wick trimmed is essential for controlling the size of the flame and ensuring an even burn.
To prevent your candle from burning too hot and melting the wax too quickly, you should trim the wick to a length of about 1/4 inch above the solid wax. This will help maintain a steady, healthy flame and extend the lifespan of your candle. It is recommended to trim the wick after the first burn and then regularly during use, especially if you plan to keep the candle burning for more than four hours at a time.
By controlling the length of the wick, you can regulate the amount of fuel being burned and prevent the wax from melting faster than it should. This will help you avoid issues such as tunneling, where only a small portion of the wax around the wick melts, and ensure that your candle burns evenly and efficiently.
In addition to keeping the wick trimmed, it is important to be mindful of the surrounding environment. Drafty areas can cause the flame to rise higher, as it has to work harder to stay lit. Therefore, it is recommended to place candles on a solid, non-drafty surface to promote a steadier burn.

The candle could be placed in a drafty area
A candle flame that is too high can be a fire hazard, especially if there are flammable objects nearby. A high flame can also cause the candle to burn too quickly, shortening its lifespan. If your candle flame is too high, it could be placed in a drafty area.
Drafts can take many forms, but you will usually feel a cool or warm breeze blowing directly on your candles or nearby. If your candle is placed in a drafty area, the flame will have to work harder to stay lit, causing it to burn higher. To reduce this risk, ensure your candle is placed on a surface that is not drafty.
Vibrations in the air may also cause your candle's flame to flicker and rise higher than normal. These vibrations can be caused by air conditioners, ceiling fans, or even the ground. If you suspect that vibrations are causing your candle's flame to be too high, try moving it to a more stable environment.
If you've tried moving your candle to a draft-free area and the flame is still too high, there may be other factors at play, such as an excessively long wick or thick wax. To address this, let the candle cool, then use a wick trimmer or scissors to trim the wick to a length of 1/4 inch above the wax. This will help control the amount of fuel being burned and promote an even burn.

The candle has been burning for too long, causing carbon build-up
Burning a candle for too long can cause carbon build-up on the wick, resulting in what is known as "mushrooming". This occurs when the candle consumes more wax than it can burn, causing the wick to become unstable and the flame to grow too large. The ideal flame size for smaller candles should be between 1/2 to 1 inch, while a flame that reaches up to 2 inches is normal for larger candles. If a candle flame exceeds this height, it may be burning too hot, causing the wax to melt faster than intended and leading to a shorter burn time.
To prevent carbon build-up and mushrooming, it is recommended to trim the wick before lighting the candle. This ensures a safe and efficient burn while extending the lifespan of the candle. It is also important to note that candles should not be burned for more than 4 hours at a time, as this can lead to carbon accumulation on the wick. Additionally, if a carbon ball begins to form on the wick, it is recommended to use a metal object to gently curve the tip of the wick towards the side of the flame, where it burns hotter.
The formation of a carbon ball, or mushrooming, can be a result of added fragrance or colouring in the wax. It can also occur when the wick is not suitable for the particular candle. Reputable candle makers typically test their candles to ensure the wick is appropriate for the wax and fragrance combination. However, if mushrooming occurs, it is important to cut off any carbon balls that form, as they can break off and fall onto the side of the candle, potentially causing a secondary flame.
In summary, to avoid carbon build-up and ensure safe and efficient burning, it is important to trim the wick, burn candles for no more than 4 hours at a time, and be mindful of any carbon balls that may form, especially with fragranced or coloured candles. By following these guidelines, you can maintain the longevity and aesthetic appeal of your candles while minimising potential safety hazards.

The wax is being absorbed faster than it can burn
If your candle flame is too big, it is burning too hot and causing the wax to melt faster than it can burn. This is caused by a long wick, which pulls up an excessive amount of wax into the flame, causing it to overheat. The ideal flame size for smaller candles should be between half an inch to one inch. A flame that reaches up to two inches can be normal for pillars and large taper candles.
To fix this issue, trim the wick to a length of about one-quarter inch above the solid wax before every burn and once every four hours if you want to keep the candle burning. This will limit the amount of fuel being burned in the candle, resulting in a calm and beautiful flame.
It is important to note that the wax is not disappearing faster. It is simply being converted into heat, light, carbon dioxide, and water vapour more efficiently. The heat from the flame causes the wax to melt, creating a small pool of liquid wax. This liquid wax is then absorbed by the wick and drawn up towards the flame, where it vaporises and reacts with oxygen in the air.
The type of wax and the size of the wick also play a role in determining the burn rate. A candle with a well-matched wick and wax will burn slower and last longer. Natural waxes, such as beeswax, soy, or coconut, burn slower and longer than paraffin wax. Additionally, ensuring a draught-free environment can help optimise burn time as a draft can cause a candle to burn faster by providing more oxygen.
