Candle tunneling, or uneven wax melting, is a common problem that can drastically reduce the total burn time of your candle. It occurs when the wick burns straight down the middle, leaving a thick ring of unmelted wax around the outside edge. This can be caused by a variety of factors, such as a wick that is too small, a strong airflow, or simply not burning the candle long enough the first time. While there are several methods to prevent tunneling, such as burning candles with multiple wicks or using a mug warmer, one popular solution is to use aluminum foil. By wrapping the candle in foil and creating a small opening for the flame, the wax is able to liquefy and even out, providing a clean, smooth burn.

Wrap the candle in foil, creating a tent with an opening for the flame
Wrapping a candle in foil is a popular method to fix candle tunnelling, or uneven wax melt. This occurs when the wick burns straight down the centre of the candle, leaving a thick ring of unmelted wax around the outside edge.
To fix this, you can use the foil to create a tent around the candle, ensuring that it is high enough so that there is space for the flame to get oxygen and continue burning. The flame should be small enough to keep the flame alive, but not so small that it extinguishes. You can adjust the size of the opening if the flame goes out. The foil should also hang over any built-up wax areas.
The foil reflects some of the heat back down at the unmelted parts, helping the wax to melt evenly. After one to two hours, the wax should have liquefied evenly. Then, blow out the candle and let it cool.
It is important to note that the quality of the wax and the shape of the container might affect how well the foil hack works.

Burn the candle for 1-2 hours
To even out a candle with foil, you must first light the candle and then wrap the candle with foil, creating a tent with an opening for the flame. This opening should be as small as possible while still allowing the flame to stay lit. The foil will reflect heat back down at the unmelted parts of the candle, allowing the wax to melt evenly. After burning the candle for 1-2 hours, the wax should have liquefied evenly. You can then blow out the candle and let it cool.
It is important to note that the size of the candle will determine how long it takes to melt the top layer of wax. Additionally, the quality of the wax and the shape of the container might affect how well the foil method works.
Candle tunneling, or uneven wax melting, occurs when only a small portion of the wax surrounding the wick melts while the candle is lit. This can be caused by a wick that is too small or by improper burning habits, such as not letting the candle burn long enough the first time it is used. To prevent tunneling, it is important to burn your candle long enough each time so that the entire top surface of the wax is melted.

Blow out the candle and let it cool
To even out a candle with foil, you must first light the candle and wrap it in foil, creating a tent with an opening for the flame. After one to two hours, the wax should have liquefied evenly. At this point, blow out the candle and let it cool.
It is important to be careful and precise when lighting or burning a candle, especially when placing aluminium foil around it. This method will help prevent tunnelling, where the wick burns a tunnel down the middle of the candle, leaving a thick ring of unmelted wax around the outside edge.
Tunnelling occurs when only a small portion of the wax surrounding the wick melts while the candle is lit, causing the tunnel to become worse over time. This can drastically reduce the total burn time of your candle. It is caused by not letting a candle burn long enough the first time it is used, or by having a wick that is too small for the candle.
To prevent tunnelling, burn your candle long enough each time so that the entire top surface of wax is melted. This is especially important the first time you burn your candle. How long this takes depends on the size of the candle, but it usually takes at least one to four hours.

Remove the foil
Removing the foil is the final step in the process of using foil to even out a candle. The first step is to wrap the candle in foil, creating a tent with an opening for the flame. After one to two hours, the wax should have liquefied evenly. At this point, you can blow out the candle and remove the foil.
It is important to be careful when lighting or burning a candle, especially when placing foil around it. This method can help prevent tunneling, where only a small portion of the wax surrounding the wick melts while the candle is lit, causing the flame to burn down the center of the candle and leaving a thick ring of unmelted wax around the outside edge.
If the tunneling issue persists, you may need to try a different method to fix it. One suggestion is to use a heat gun on low to melt the entire top of the candle and establish a full melt pool. Then, use a paper towel to remove the wax and even the surface before lighting the candle again.
Another method is to use a hairdryer or heat gun to melt and smooth out the wax. Place some newspaper around the candle to catch any splatters, and gently heat the top surface of the candle to soften the unmelted edges. If using a hairdryer, set it to high heat and low speed. Alternatively, you can put the candle in the oven at 175 degrees Fahrenheit for 2-5 minutes to evenly melt the top.

Let the wax harden
After removing the aluminium foil, let the wax harden. It is important to let the wax harden over a few days to reach full hardness. Wax will continue to harden over time, even in its solid, unmelted state. Candle wax that was melted and cooled again yesterday will always be softer than candle wax that has been sitting for a week. The wax in the centre that melted first will be softer and will therefore melt quicker the next time the candle is lit. The surrounding wax that didn't melt the first time is harder in comparison and won't melt, leading to candle tunnelling.
The foil method is a quick fix to prevent candle tunnelling, or uneven wax melt, but it is not a permanent solution. The candle will continue to tunnel unless you let the wax harden completely. The foil method works by reflecting some of the heat back down at the unmelted parts of the candle, encouraging the wax to melt evenly. However, if the candle is not allowed to cool and harden completely, the tunnelling will continue the next time the candle is lit.
The foil method is also not suitable for deep tunnels. In this case, you could try using a mug warmer to melt the leftover wax and release the scent. Alternatively, you could use a hairdryer or heat gun to melt and smooth out the wax. Lay some newspaper around the candle to catch any splatters, and gently heat the top surface of the candle to melt the edges. Direct the heat from about six inches away at the unmelted edges until the wax softens.
If you have already used the foil method and blown out the candle, let the wax harden completely before lighting the candle again. This will help to prevent further tunnelling and ensure a more even melt the next time you light the candle.

You can use a hair dryer or heat gun to melt and smooth out the wax of a tunnelled candle. If you are using a hair dryer, be sure to set it on high heat and low speed. You can also put your candle in the oven at 175 degrees Fahrenheit for about 2-5 minutes to evenly melt the top.
To prevent candle tunnelling from happening again, consider buying candles with multiple wicks and letting them burn for several hours the first time you light them.
