Lopsided candles, also known as candle tunneling, are caused by a variety of factors, including the quality of the wax, the size of the wick, and exposure to drafts of wind. Candle tunneling is when the wick burns straight down the center, creating a vertical tunnel and leaving hard wax around the outside. This results in an uneven burn, affecting the candle's appearance, scent, and burn time. To fix a lopsided candle, you can use methods such as the aluminum foil trick, oven method, hairdryer technique, or trimming the wax surface. These methods aim to forcibly melt the entire wax surface to reset its memory, allowing it to solidify evenly and burn uniformly in the future.
Characteristics and Values Table for Fixing a Lopsided Candle
| Characteristics | Values |
|---|---|
| Cause | Consistent draft over a longer period of time, e.g. wind from a window, vent, or fan |
| Prevention | Burn candles on a level surface |
| Identification | Uneven melt pool, slanted melt pool, unmelted layer of wax underneath is not smooth and level, flame is not calm and steady |
| Fix | Forcibly melt the entire surface of the wax to "reset" its memory, then allow the wax to settle back into a smooth, even surface; use a hair dryer, oven, tin/aluminum foil, or heat gun |
| Fix for Minor Tunneling | Blast the top of the candle with a hair dryer on high heat until the top layer of wax has melted and smoothed |
| Fix for More Serious Tunneling | Light the candle, wrap a layer of tin/aluminum foil around the top, creating a domed lip with a hole in the top to allow heat to stay concentrated and melt the rim of hard wax on the sides |
| Fix for Homemade Candles | Heat the wax using a hair dryer, oven, or heat gun until the entire surface melts, then light the candle for at least 30 minutes before blowing it out and letting it sit for 2 days |

Fix minor tunneling with a hair dryer
A lopsided candle, or tunneling, occurs when a candle burns down its centre, leaving hard wax around the outside. This happens when a candle is not burned carefully, and it can drastically reduce the total burn time of your candle. Luckily, if you catch it early enough, you can fix minor tunneling with a hair dryer.
First, lay some newspaper around the candle to catch any wax splatters. Then, turn your blow dryer on high heat and low speed. Keep the hair dryer a good distance from the candle so that the wax does not spit out of the vessel as it melts. Gently heat the top surface of the candle from an appropriate distance. You can carefully scrape at the unmelted wax on the sides with a wick dipper or small metal spatula to help it melt faster.
Continue heating until the entire top surface of the wax has completely melted and smoothed over. This may take several minutes, depending on how hot your hair dryer gets. Then, allow your candle to fully harden, approximately 4 hours, before lighting it again.
While this method is great for when a light memory ring begins to form, it is important to note that if you ignore a memory ring for too long, it will continue to create a deep tunneling effect. If your candle is showing more serious signs of tunneling, you may need to try a different method, such as the foil method.

Use the oven to melt the wax surface
If your candle is showing signs of tunneling, you can use an oven to melt the wax surface and fix the issue.
First, trim the candle's wick and remove any debris from the surface. Then, set your oven to a low temperature of around 175°Fahrenheit (or the lowest setting if your oven doesn't have specific temperature settings). Place the candle inside the oven and leave it for about 2 to 5 minutes. Keep an eye on it and check in between to ensure the wax is melting evenly. Once the entire surface has melted, carefully remove the candle from the oven. If there is any excess wax that has melted over the wick, scoop it out. Allow the wax to cool and settle back into a smooth, even surface.
This method works by heating the entire wax surface, allowing it to reset and level out. It is important to note that this approach is best used when the tunneling is caught early. If your candle shows more serious signs of tunneling, you may need to try a different method, such as using aluminum foil or a hairdryer, in addition to or instead of using the oven.
When using the oven method, always exercise caution and ensure that you are using an oven-safe container for your candle. Do not leave the candle unattended, and be careful when handling the hot container after removing it from the oven.
By following these steps, you can effectively use the oven to melt the wax surface of a lopsided candle and restore its even burn.

Wrap the candle in aluminum foil
If your candle is showing signs of tunneling, you can use the aluminum foil method to fix it. This method works by wrapping the candle in foil, which allows the heat to stay concentrated within the candle and melt the surrounding wax, thereby fixing the tunneling.
First, light your candle. Then, carefully wrap a layer of aluminum foil around the top of the candle, forming a domed lip with a hole in the top. Make sure the foil hangs over any built-up wax areas, but leave an opening in the centre so the wick can still burn properly. For larger candles, ensure that the opening in the centre of the foil is large enough to allow plenty of oxygen in as the candle burns.
Once the candle is wrapped in foil, let it burn for at least half an hour before blowing it out. After that, let the candle sit for two days or more to allow the wax to solidify completely.
It's important to note that the quality of the wax and the shape of the container may affect how well the foil method works. This method works best with smaller candles, as larger candles may not generate enough heat to melt the wax.
In addition to the aluminum foil method, you can also use a hair dryer, oven, or grill to fix candle tunneling. These methods involve heating the wax to allow it to melt and smooth out.

Burn your candle on a level surface
Burning your candle on a level surface is a simple yet effective way to prevent it from burning unevenly and becoming lopsided. When a candle is burned on an uneven surface, the melt pool will appear slanted, and the candle will develop a lopsided appearance. This is because the candle itself is tilted, and the wax will melt unevenly.
To ensure your candle burns evenly, always place it on a level surface before lighting it. Check that the surface is flat and stable, and avoid placing the candle near an open window, vent, or fan, as consistent airflow can also cause uneven melting.
By taking this simple precaution, you can help ensure that your candle burns evenly and that you get the most out of your purchase.
Additionally, when burning a new candle for the first time, it is important to let it burn long enough to create a full melt pool across the entire surface. This will help prevent candle tunneling, where the wick burns down the center, leaving hard wax around the outside. Candle tunneling not only looks unsightly but also reduces the burn time and scent throw of the candle.

Trim the wick and remove debris
Trimming the wick of your candle is a crucial step in candle maintenance and can help prevent issues such as lopsided candles. The ideal height of a candle wick is typically between 1/4 inch to 1/2 inch, although some sources recommend keeping it up to 1 inch long. Trimming the wick ensures that the candle burns evenly and at a steady rate, preventing tunneling. Tunneling occurs when the flame gets too hot and causes excess wax to burn, resulting in a lopsided candle with unmelted wax around the edges.
To trim the wick, use a sharp pair of scissors or wick trimmers to cut the wick vertically, ensuring a straight and even cut across. Avoid cutting at an angle for a cleaner burn. If you accidentally cut the wick too short, you can try the methods suggested by Aisha Cort, the founder of VELA NEGRA Candles. Start by lighting the candle and letting it burn for about 30 minutes to create a wax pool. Then, extinguish the flame and carefully pour out the melted wax using a butter knife or similar tool. Alternatively, soak up the wax with a paper towel or pour it into a paper cup.
It is also important to remove any debris, such as excess wax or soot, from the candle and its surroundings. Soot buildup can occur due to long wicks, resulting in black smoke stains on the candle vessel or nearby items. To remove soot, simply wipe it off with a dry napkin or towel once the candle has cooled down.
Trimming the wick before each burn is essential to maintaining a healthy flame height and prolonging the life of your candle. A wick that is too long can lead to a tall flame, increasing the risk of fire and causing the candle to burn too quickly. Therefore, regular wick trimming is necessary to ensure an optimal burning experience and prevent issues like tunneling and lopsidedness.
By following these wick trimming and debris removal steps, you can help prevent your candle from burning unevenly and correct any minor lopsidedness that may occur. However, for more serious cases of lopsidedness or tunneling, additional methods, such as using a hairdryer or the foil method, may be required.
