Candle tunneling is a common problem that occurs when only a small circle of wax around the wick melts, instead of the entire surface. This results in wasted wax and can make it difficult to light the candle. To prevent tunneling, it is recommended that each time you light a candle, you let it burn long enough for the wax to melt to the edge of the container. This is especially important the first time you light a new candle. If tunneling does occur, there are several methods you can use to fix it, including using a hair dryer, oven, or aluminum foil to melt the wax to the edge of the container.

What You'll Learn
Use a hairdryer or heat gun to melt the wax
Using a hairdryer or heat gun is an effective way to melt the sides of a candle and prevent or fix candle tunneling. Candle tunneling occurs when a candle burns down its centre, leaving hardened wax around the outside. This not only looks unsightly but also means you're missing out on the full burning and scent potential of your candle.
To fix this issue with a hairdryer or heat gun, follow these steps:
Firstly, ensure you are wearing eye protection and clothing that can be washed if wax gets on it. Then, trim the candle wick and remove any debris inside the tunnel. Next, turn on your hairdryer or heat gun, setting it to low speed and high heat. Gently heat the top surface of the candle from a safe distance, being careful not to blow melted wax everywhere. Continue heating until the entire top surface of the wax has melted and smoothed over. This may take several minutes, depending on the heat of your hairdryer or heat gun, so patience is key.
If you're using a hairdryer, you can also try a slightly different method. Light your candle and carefully wrap a layer of foil around the top, creating a domed lip with a hole for the wick. This concentrates the heat and helps melt the hardened wax on the sides. After an hour or so, carefully remove the foil, and you should have an even wax pool.
By using a hairdryer or heat gun, you can effectively melt the sides of your candle, ensuring an even burn and maximising the enjoyment of your candle's scent.

Wrap the candle in foil to reflect heat
Wrapping a candle in foil is a great way to fix candle tunneling, a common issue where a ring of dry, hard wax forms around the outside edge of the candle, which can cause the candle to become difficult to light.
To wrap the candle in foil, you will need one or more sheets of aluminum foil. Start by placing the candle on a flat surface and tearing off a sheet of foil that is long enough to wrap around the candle. The foil should be wide enough to cover the unmelted portion of the candle, with some extra length to spare. Wrap the foil around the outside of the candle, ensuring that the top edge of the foil extends inward over the unmelted wax, creating a tent-like structure. The center of the candle should remain open for the flame.
Once the candle is securely wrapped in foil, you can light the wick. The foil will reflect the heat of the flame back down towards the unmelted wax, helping to melt it evenly. It typically takes around 2-3 hours for the candle's surface to even out, creating a pool of melted wax that reaches the edge of the container.
It is important to exercise caution when using this method, as the foil will become hot. Always allow the foil to cool before adjusting or removing it. Additionally, be mindful of the flame and avoid leaving the burning candle unattended, especially around pets, children, drafts, or flammable objects.

Burn for longer periods to fully melt the top layer
Burning your candle for longer periods is a crucial step in preventing the "tunnel" effect and ensuring it burns evenly and efficiently. The first burn sets the stage for the life of the candle. When you burn a new candle, it's important to let it burn long enough for the wax to melt all the way to the edges, creating a wide opening for future burns. This usually takes 1-2 hours, depending on the candle's size, with a general rule of thumb being one hour for each inch of diameter. For example, if your candle is 3 inches wide, it should be burned for at least 3 hours initially.
By allowing the candle to burn longer during its first use, you prevent the formation of a hard wax ring around the outside edge that refuses to melt. This ring, or tunnel, can make it difficult to light the candle and results in wasted wax. The longer your candle burns during its initial use, the bigger the opening for subsequent burns, and the less likely you are to experience tunneling.
To achieve a complete melt of the top layer, there are a few additional techniques you can use alongside longer burn times. Firstly, ensure that you trim the wick to about a quarter of an inch before lighting the candle. This promotes a cleaner, more consistent burn. Additionally, keep the candle away from drafts of air, such as open windows or fans, as moving air can disturb the flame and cause unsightly marks on the glass.
If you're dealing with a candle that has already developed tunneling, you can try the following: place the candle in an oven set to 175°F for about five minutes to allow the wax to melt and level out. Alternatively, use a hair dryer on a low setting, holding it far enough away from the candle to avoid spattering wax. You can also use aluminium foil to reflect heat back down to the candle's edge, aiding in melting the wax. However, be cautious when using foil as it can get very hot.

Trim the wick to 1/4 inch before lighting
Trimming the wick of a candle to 1/4 inch before lighting it is crucial for several reasons. Firstly, it ensures an even and consistent melt across the candle's surface, preventing the common issue of "candle tunnelling." This phenomenon occurs when the flame drops below the wax's top layer, leaving a hard ring that doesn't melt, resulting in wasted wax and a challenging-to-light wick. Trimming the wick encourages a steady and controlled flame, reducing the risk of excess heat that could lead to an accelerated burn rate and uneven wax pooling.
Trimming the wick to the recommended length also helps maintain a healthy flame height, typically between 1/2 inch and 1 inch. This range ensures the candle burns at a safe and optimal rate, reducing the risk of fire hazards. Additionally, an appropriately trimmed wick prevents the flame from becoming too tall, which can cause incomplete combustion and the production of unsightly soot and black marks on the glass. By keeping the wick trimmed, you minimize the buildup of soot, improving indoor air quality and maintaining a clean and pleasant burning experience.
The type of wick and wax blend will also determine the ideal wick height. While the general recommendation is to keep cotton or wooden wicks between 1/4 inch and 1/2 inch in height, some candles may require slight adjustments. It's important to refer to the candle manufacturer's instructions or experiment with the flame to find the optimal wick height for a particular candle.
Trimming the wick before lighting is a crucial step in candle care, and it's recommended to use a wick trimmer, scissors, or even nail clippers to achieve the desired length. This practice ensures a long, even, and fragrant burn, maximizing the candle's performance and burn time while minimizing the risk of fire hazards and maintaining a clean and safe burning environment.

Place the candle in an oven for 5 minutes at 175°F
If you want to melt the sides of a candle, you can use an oven. This method is particularly useful for fixing candle tunnelling, which is when the flame begins to drop below the top-level wax, leaving a hard ring that won't melt.
Firstly, set your oven to 175°F. It is important to ensure the oven is fully preheated before inserting the candle, so the wax doesn't melt too much. Place the candle in the middle of a cookie sheet and put it in the oven for around 5 minutes.
After this time, carefully remove the candle from the oven using oven mitts to protect your hands. If there is excess wax that has melted over the wick, scoop this out with a butter knife or spoon. Then, allow the wax to harden before lighting the candle again.
If you still notice tunnelling, return the candle to the oven and check after another 1-2 minutes. This method is quick and easy, and helps to level out the candle's surface without disturbing its vessel.
