Candle tunnelling is a common issue that can be frustrating for candle lovers. It occurs when a hole forms down the centre, leaving unused wax at the edges. This not only wastes your candle but also shortens its lifespan. Luckily, there are several ways to fix a tunnelling candle and prevent it from happening again. Firstly, it's important to ensure that your candle is burning evenly during the first burn by letting it burn for at least 2-3 hours or until the entire surface is melted. Additionally, choosing the right size wick for your candle and trimming it to 1/4 inch before each use can help prevent tunnelling. If your candle has already started tunnelling, you can try using a hairdryer or the tin foil method to melt the hardened wax around the edges.
Why do candles tunnel?
| Characteristics | Values |
|---|---|
| Candle isn't burned long enough | The first burn is significant in candle care. If the candle isn't burned long enough, an initial layer of wax from edge to edge remains unmelted, causing tunneling. |
| Improper wick size | A wick that is too short or thin may not produce enough heat to melt the wax from edge to edge. |
| Poor wax composition | Cheap candles with poor wax composition may not melt evenly. |
| Drafty conditions | Drafts can cause uneven burning. |
| Candle isn't burned carefully | Wax has a "memory." If the candle isn't burned carefully, the wax will continue to harden over time, causing tunneling. |

The initial burn is key: Ensure the first burn is long enough to melt the entire top layer of wax
The first burn of a candle is critical to its overall performance. This is when the wax first melts and creates a "melt pool". The size and depth of this melt pool will determine how long your candle will last and how evenly it will burn.
Ensuring the first burn is long enough to melt the entire top layer of wax is crucial to preventing tunnelling. Tunnelling is when the wax burns down the middle, leaving wax on the sides of the jar. This can ruin a perfectly good candle, affecting its aesthetic appeal, burn time, and scent throw.
The optimal amount of fragrance is released when the entire top of the candle, the melt pool, becomes completely liquified. Allowing the wax to melt all the way to the edges during the first burn will prevent tunnelling and extend the life of your candle.
To achieve this, a good rule of thumb is to let your candle burn for at least one hour per inch of container diameter. For instance, if the candle container has a diameter of three inches, you should let it burn for at least three hours during the first burn. However, you should not let it burn for longer than four hours without extinguishing the flame and trimming the wick.
Additionally, trimming the wick before each burn is important to prevent soot and extend the life of your candle. The first burn is the perfect opportunity to trim the wick to the proper length, which is usually between 3mm to 5mm, or 1/8 to 1/4 of an inch.

Wick issues: An incorrectly sized wick may not produce enough heat to melt wax from edge to edge
Candle tunnelling is a common issue that can occur with candles of any price point. It happens when a hole forms down the centre of the candle, leaving unused wax at the edges. This can drastically reduce the total burn time of your candle, as well as affecting its scent throw.
One of the most common causes of tunnelling is wick issues. If the wick is too small for the volume of wax or the width of the vessel, it may not be able to produce enough heat to burn the wax from edge to edge. This is known as being "underwicked".
To prevent tunnelling, it's important to ensure that your wick is the correct size for your candle. If you're making your own candles, you can refer to online guides to help you choose the right wick. If you're buying candles, look for those with multiple wicks, as these will distribute heat more evenly and reduce the chances of tunnelling.
If your candle has already started tunnelling, there are a few things you can try to fix it. One method is to use a hairdryer to melt the hardened wax around the edges of the container. You can also try the aluminium foil method, which reflects heat back down to the candle's edge to aid in melting the wax. Another option is to scoop out the unmelted wax with a spoon until it is level with the melted section in the middle.

Wax composition: Cheap candles with poor wax composition may not melt evenly
Candle tunnelling can be attributed to several factors, one of the most common being the quality of the wax. Cheap candles are often made with low-quality wax, which may be too soft or have an uneven distribution of ingredients, causing uneven burning and tunnelling.
Wax is made up of a combination of substances, typically including a hard substance like paraffin or beeswax, and softer substances like soy wax or palm wax. The ratio of hard to soft substances in the wax affects how the candle burns. If a candle has too much soft wax, it will burn faster and more unevenly, increasing the likelihood of tunnelling.
Additionally, the quality of the hard substances in the wax plays a crucial role. High-quality hard substances, such as beeswax, have a higher melting point and burn more slowly and evenly. On the other hand, cheap candles often use low-quality paraffin wax, which has a lower melting point and tends to soften and melt more quickly, leading to uneven burning and tunnelling.
To avoid tunnelling due to poor wax composition, opt for candles made with high-quality wax. Look for candles that use natural waxes like beeswax or soy wax, which are known for their slower and more even burning properties. Candles made with a blend of hard and soft waxes can also perform well, provided the

Drafty conditions: Drafts can cause uneven burning, leading to tunnelling
Drafts can cause candles to burn unevenly, leading to tunnelling. Tunnelling is when a hole forms down the centre of a candle, leaving unused wax at the edges. This can be caused by various factors, including drafty conditions. Drafts can cause the flame to flicker and move, leading to uneven melting of the wax. This can result in the formation of a tunnel as the flame carves out a vertical path through the wax.
To prevent tunnelling caused by drafts, it is important to ensure that your candle is in a draft-free location. Choose a calm area away from open windows, doors, or vents. If your candle is in a drafty area, try moving it to a more sheltered spot. Additionally, you can use a candle shield or a candle jar to protect the flame from drafts. These barriers create a protected environment, minimising the impact of airflow on the flame and reducing the likelihood of tunnelling.
If your candle has already started to tunnel due to drafts or other factors, there are several methods you can use to fix it. One common approach is to use aluminium foil or tin foil to reflect heat back down to the candle's edge. Wrap the foil around the outside of the candle, leaving an opening at the top for the flame to burn safely. This technique concentrates the heat, helping to melt the outermost wax and creating an even melting surface.
Another method to address tunnelling is to use a hairdryer to melt the wax evenly. First, extinguish the flame, then use the hairdryer on a low setting to carefully melt the wax to the edge of the container. This process removes the "memory" of the wax, allowing it to reset and burn more evenly in the future. Always exercise caution when using a hairdryer to avoid spattering any hot wax.
Additionally, you can try the "hugging your candle" technique. After blowing out the candle, allow it to cool for a minute. Then, gently push the non-melted edges of the wax down with your fingertip until the surface is level. This method helps to create an even melting pool, reducing the chances of tunnelling.

Fixing tunnelling: Use a hairdryer to melt the wax to the edge of the container
Candle tunnelling is a common problem that occurs when a candle burns down the centre, leaving unused wax at the edges. This happens when a candle isn't burned long enough during its first few burns, preventing the wax from melting to the edge of the container. This creates a "'memory'" in the candle, where the wax that has already been melted will re-melt more easily than the wax that hasn't, resulting in a tunnelling effect.
To fix tunnelling, you can use a hairdryer to melt the wax to the edge of the container. Here's how to do it:
- Ensure that the candle is extinguished.
- Use a hairdryer on a low setting to melt the wax. Hold the hairdryer far enough away from the candle to avoid spattering any wax.
- Continue heating the wax until it has melted to the edge of the container, or nearly so. This will remove the "memory" of the wax, allowing it to melt evenly in the future.
- Allow the wax to cool and solidify before relighting the candle.
This method is most effective when the tunnelling is still shallow (less than 1/2 inch deep). For deeper tunnels, you may need to combine this method with other techniques, such as using aluminium foil to reflect heat back to the candle's edge. Always exercise caution when working with hot wax and open flames, and be sure to follow general candle safety guidelines.

Frequently asked questions
Candle tunnelling is a common problem that occurs when a candle isn't burned carefully. It's usually the result of irregular burning practices, such as not allowing enough time for the entire surface of the candle to melt before blowing it out.
To prevent tunnelling, ensure that your candle is burned long enough during its first few burns for the wax to melt to the edges of the candle container. You can also use a candle warmer, an electric device that melts candles without an open flame, producing a consistent and uniform heat that melts the wax evenly.
If your candle has started tunnelling, you can try the aluminium foil method. Wrap foil around the candle's base and upper edge, leaving an opening at the top for the flame to burn safely. The foil concentrates the heat, helping to melt the outermost wax. You can also try melting the entire candle surface with a hairdryer or heat gun.
