Candle wicks mushroom due to the wrong size wick
Candle wicks can start to mushroom due to several reasons, one of the main ones being the size of the wick. If the wick is too big, it will burn too hot, drawing more wax to the flame than it can handle. This leads to a build-up of carbon particles, forming a small, mushroom-shaped protrusion at the top of the wick. This is known as a "mushroom wick".
To prevent mushrooming, it is important to choose a candle with a wick that is appropriately sized for its container. The wick should be centred in the middle of the candle to ensure an even melt pool. A wick that is too large for the candle's diameter will cause the candle to burn too hot, resulting in carbon build-up and mushrooming.
The type of wax used can also affect mushrooming. For example, soy wax is recommended for soy candles to prevent mushrooming. Additionally, burning candles for shorter periods can help reduce the likelihood of mushrooming.
If mushrooming does occur, it is a simple fix. Simply trim the black cap off the top of the wick and straighten the wick as normal. This will remove the excess carbon build-up and allow the candle to burn cleanly again. However, if mushrooming has occurred once, it is likely to happen again with the same wick, so it may be necessary to replace the wick with a new one that is the correct size.
Overall, while candle wicks mushrooming can be unsightly and indicate an issue with the burning conditions, it is a common and easily fixable problem. By choosing the right size wick, using the correct type of wax, and burning candles for shorter periods, mushrooming can be reduced or prevented altogether.

The ratio of wax to wick is off
The phenomenon of candle wicks mushrooming is often due to an imbalance in the ratio of wax to wick. This occurs when the wick is too large for the candle's diameter, causing it to burn too hot and consume more wax than it can efficiently burn. As a result, there is a build-up of carbon particles, forming a small, mushroom-shaped structure at the wick's tip. This issue can be mitigated by selecting a wick that is appropriately sized for the candle's container.
When creating candles, it is crucial to choose the right type and size of wick to prevent mushrooming. The wick should be centred to achieve an even melt pool. Various tools, such as wick sustainers and stickums, can help position the wick during the pouring process. Additionally, ensuring that the wick is straight and upright while the candle cools can be achieved with a wick-centering tool.
The type of wax used also plays a role in preventing wick mushrooming. Different types of wax require specific wick types for optimal burning. For example, TCR wicks are recommended for soy wax, LX wicks for paraffin waxes, and the ECO range offers an all-rounder option. By selecting the appropriate wick for the chosen wax, you can reduce the likelihood of mushrooming.
To address wick mushrooming, it is advisable to trim the wick when the candle is not burning. This simple fix removes the excess carbon buildup and restores the wick to its normal state. However, to prevent future occurrences, it may be necessary to replace the wick with one that is correctly sized for the candle's dimensions.
While wick mushrooming may seem like a mere aesthetic issue, it can indicate suboptimal burning conditions. By understanding the underlying causes, such as the ratio of wax to wick being off, candle makers can improve their craft and provide customers with a cleaner and more enjoyable burning experience.

The wick is standing straight up
The phenomenon of candle wicks mushrooming is caused by a build-up of carbon particles, which occurs when the wick burns too hot. This happens when the wick is too large for the candle's diameter, causing more wax to reach the flame than it can handle. As a result, the flame is unable to burn all the wax, leading to the formation of a mushroom-shaped protrusion at the wick's end.
While some may find mushrooming aesthetically pleasing, it can indicate an issue with the candle's burning conditions. To prevent this issue, it is recommended to choose a candle with a wick that is appropriately sized for its container. A wick that is too thick will be more prone to mushrooming, whereas a thinner wick that is bent at a gentle angle will be less likely to experience any build-up.
Maintaining the correct positioning of the wick is also important. Using tools like wick sustainers and wick stickums can help keep the wick centred during the pouring process, ensuring an even melt pool. Additionally, a wick that stands straight up is more susceptible to mushrooming compared to a gently angled wick.
If mushrooming does occur, it is easily remedied by simply trimming the black cap off the wick and straightening it. However, if you are a candle maker, repeated occurrences of mushrooming may be problematic, and it may be advisable to opt for a different type of wick.

The candle has been burning for too long
If your candle has been burning for too long, it may start to mushroom. This phenomenon occurs when the wick of a candle burns too hot, causing a build-up of carbon on the wick that creates a small, mushroom-shaped protrusion. It is a common occurrence and can be prevented by opting for a different type of wick or wax, or by burning candles for shorter periods.
The candle wick acts like a straw, absorbing wax and sending it to the flame. If the wick is too big, it will draw more wax than the flame can burn, leading to carbon buildup and the formation of a mushroom wick. This is more likely to happen when a wick stands straight up, as a wick that is bent at an angle is less likely to have any buildup.
To prevent mushrooming, it is important to choose a candle with a wick that is appropriately sized for its container. A wick that is too large for the candle's diameter will burn too hot and cause the carbon build-up that leads to mushrooming. By selecting a wick that is the correct thickness for your container, you can ensure a good burn.
In addition to wick size, the type of wax used can also impact mushrooming. For example, soya wax is recommended for use with TCR wicks, while paraffin waxes pair well with LX wicks. Using the correct type of wick for the specific type of wax can help to prevent mushrooming.
If mushrooming does occur, it is important to trim the wick when the candle is no longer burning. This simple fix will remove the excess carbon buildup and allow the candle to burn cleanly once again.

The wick is not centred
A wick that isn't centred can cause issues with mushrooming. When a wick is off-centre, it can lead to uneven burning, which in turn can cause the wick to mushroom. This is because an off-centre wick may not be able to draw wax evenly, resulting in a larger flame that consumes more wax than it can burn. This leads to a build-up of carbon on the wick, forming the characteristic mushroom shape.
To prevent this, it is crucial to ensure that the wick is centred correctly during the candle-making process. This can be achieved by using wick sustainers or wick stickums to keep the wick adhered to the bottom of the container while the wax is poured in. A wick centring tool can also be used to ensure that the wick remains straight and upright as the candle cools.
Additionally, choosing the right size of wick for the candle's diameter is essential. A wick that is too large will burn too hot, contributing to the carbon build-up that causes mushrooming. Opting for a wick that is appropriately sized for the container will help prevent this issue.
By taking these steps and ensuring the wick is centred and the correct size, you can reduce the likelihood of mushrooming and improve the overall burning experience of your candles.
If you are experiencing mushrooming due to an off-centre wick, there are a few simple fixes you can try. Firstly, trim the black cap of the wick and straighten the wick. You can also try dipping the wick in wax or purchasing a wick-dipping kit to remove the excess build-up. However, to completely avoid mushrooming, addressing the underlying issue of wick placement and size is necessary.
