An uneven candle burn, also known as candle tunnelling, is when a candle burns down its centre, leaving hard wax around the outside. This results in an unappealing look and a shorter burn time. To fix this, you can use the foil method, which involves wrapping foil around the top of the candle, leaving an open circle for the flame, and lighting the candle as normal. After about an hour, the wax should melt evenly. Alternatively, you can forcibly melt the entire surface of the wax and allow it to settle into a smooth, even surface.

What You'll Learn

Use tin foil to reflect heat back to the candle's edge
If your candle is burning unevenly, it's time to try the tin foil method. This method is relatively easy, but remember to proceed with caution as the foil can get hot. First, light your candle. Then, carefully wrap a layer of tin foil around the top of the candle, creating a domed shape with a hole in the top. Make sure there is an open circle where the wicks are, but the foil should cover the outside ring of the candle. This will allow the heat to stay concentrated within the candle and help melt the rim of hard wax on the sides.
The tin foil method works by reflecting heat back down to the candle's edge, aiding in melting the wax. This technique is particularly useful if your candle is showing more serious signs of tunneling, which happens when a candle burns down its centre, leaving hard wax around the outside. Not only does this look unappealing, but it also reduces the burn time of your candle as only a small portion of the wax is consumed.
After about an hour or so, carefully remove the foil. You should now have a pool of evenly melted wax. If you don't succeed the first time, don't worry; this method may take a few tries to perfect. Remember to let the foil cool down before adjusting or removing it.
To prevent your candle from burning unevenly in the future, it is important to ensure that the first burn is complete. This means allowing the entire surface layer of wax to melt, which usually takes 1-2 hours depending on the size of the candle. If you blow out the candle too early, you may create a "'memory ring', which can lead to tunneling in subsequent burns.

Melt the entire surface of wax to reset its memory
If you notice your candle is burning unevenly, it is important to forcibly melt the entire surface of the wax to "reset" its memory. This process will help you achieve a smooth and even wax surface and improve your candle-burning experience.
Firstly, light your candle and let it burn for a while. Then, carefully blow dry the top layer of wax with a hair dryer on high heat until it has completely melted and smoothed out. Make sure you direct the airflow only over the wax's top layer. This method is ideal for addressing minor tunneling issues.
Alternatively, you can use the foil method for more serious tunneling problems. Wrap a layer of tin foil around the top of the candle, creating a domed shape with a hole in the centre for the flame. This technique reflects heat back to the candle's edge, aiding in melting the wax. Leave the candle burning for about an hour, then carefully remove the foil. You should now have an even wax pool. Caution should be exercised when handling the foil, as it can get very hot.
Another way to reset the memory of your candle is to use a candle warmer. This device will melt the wax and release the scent without the need for a flame.
Remember, candle tunneling occurs when only a small circle of wax around the wick melts while burning, instead of the entire surface. This issue can be prevented by ensuring that the first burn of a new candle lasts long enough for the wax to melt to the edge of the container.

Ensure the first burn is long enough to melt the entire surface layer
Ensuring that the first burn of a candle is long enough to melt the entire surface layer is crucial to prevent tunnelling and ensure an even burn. Tunnelling occurs when only the wax surrounding the wick melts, resulting in a narrow hole or tunnel in the centre of the candle. This phenomenon causes the candle to burn out faster and can make it look unappealing.
To prevent tunnelling, it is essential to allow the candle to burn long enough during its initial use for the wax to melt evenly across the entire surface. This process can take a few hours, depending on the size of the candle. As a general rule of thumb, candles should burn for one hour per inch of container diameter. For example, a candle with a diameter of 3.25 inches should be burned for at least three hours during its first use.
It is important to note that drafts from windows or vents can cause the flame to flicker or bend, leading to an uneven burn. Therefore, candles should be burned away from consistent drafts and on a level surface to ensure an even melt pool. Additionally, keeping the wick trimmed to about 5mm helps control the size of the flame and promotes an even burn.
By following these guidelines, you can ensure that your candle burns evenly and lasts longer. A candle with a good wax memory will burn uniformly, allowing you to enjoy its full fragrance and a more pleasant candle-burning experience.

Replace wicks by poking a hole in the wax and inserting a new wick
If your candle is burning unevenly due to a drowned wick, you can replace the wick by poking a hole in the wax and inserting a new one. Here is a step-by-step guide:
- Poke a deep hole in the wax right next to the drowned wick using a skewer, knitting needle, or chopstick.
- Prepare your new wick by dipping it in wax. You can use the wax from the candle you are replacing, or from another old candle. This will help the new wick burn more slowly and evenly.
- Carefully insert the new wick into the hole, ensuring that it sits right beside the old wick.
- Trim the new wick to the correct length, leaving about 1/4 inch exposed.
- Light the candle and allow it to burn until the melted wax pool completely covers the entire surface. This will help reset" the candle's memory and promote even burning in the future.
It is important to note that this method is easier with shorter candles, as longer candles may have more wax to dig through to reach the drowned wick. Additionally, if your candle has a wick tab (a metal piece that holds the wick in place), removing the wick tab with pliers can be difficult, especially if the candle depth is filled too high. In this case, you may need to melt the wax around the wick tab and pour it back into the candle after inserting the new wick.

Use a candle warmer to melt the wax without a flame
If your candle is burning unevenly, you can use a candle warmer to melt the wax without a flame. This method is ideal for when your candle is too far gone to be fixed by other methods.
A candle warmer will melt the candle's wax and release its scent without the need for a flame. This method is a good option if you want to enjoy your candle without burning it, or if you want to fix a candle that has tunnelled too far down.
To use a candle warmer, simply place your candle on the warmer and turn it on. The warmer will slowly melt the wax, releasing the fragrance. You can leave the candle on the warmer for as long as you like, and turn it off whenever you want to enjoy the scent.
Candle warmers are a safe and easy way to enjoy your candles. They are also a good option if you have pets or children, as there is no open flame. You can also use a hair dryer on a high heat to melt the top layer of wax until it is smooth and even, but be careful to let the wax cool before moving the candle.

Frequently asked questions
To check if your candle is burning evenly, observe if the melt pool has extended to the edge of the jar. The unmelted layer of wax underneath should be smooth and level, and the flame should be calm and steady.
One way to fix an uneven candle is to forcibly melt the entire surface of the wax to reset its memory. Then, allow the wax to settle back into a smooth, even surface. This can be done by using a hair dryer or a candle warmer to melt the top layer of wax. Alternatively, you can use tin foil to reflect heat back down to the candle's edge, aiding in melting the wax.
To prevent uneven burning, ensure that during the first burn, you allow enough time for the entire surface layer of wax to melt. Do not blow out the candle if there is any unmelted wax remaining on top. As a general rule, let the candle burn for at least one hour per inch of container diameter.
An uneven candle burn, also known as candle tunneling, can be caused by an incorrectly made candle with a wick that is too small for the container. However, it is more commonly caused by an insufficient first lighting duration.
