Candle tunnelling is a condition where the wax only melts in the center, forming a kind of hole or tunnel, while the rest of the wax around it remains intact and does not burn. This condition is very unfortunate because it wastes the wax and does not burn evenly. This problem often occurs in scented candles or candles in containers that can reduce the lifespan of the candle, reduce the visual beauty and reduce the aroma produced. In order to optimise the use of candles, this article will discuss how to stop tunnelling from happening and easy steps to overcome tunnelling if you have already experienced it.
How to Prevent Candle Tunneling
Preventing candle tunneling is actually easier than fixing it, as long as you know the right steps from the start. Here are some effective ways to prevent candle tunnelling so that the candle burns evenly and lasts longer:
1. Let the candle burn for a long time when first using it
When you first light a candle, make sure it burns until the entire surface of the wax melts all the way to the edges. Avoid burning the candle for only a short time (less than 30 minutes), as this is what triggers tunnelling.
2. Trim the wick before use
Always trim the wick of your candle to about 1/4 inch (0.5 cm) before lighting. A wick that is too long can create a flame that is too large or unstable, causing uneven burning.
3. Avoid placing candles in drafty areas
Wind from fans, open windows, or air conditioning can make candle flames inconsistent and melt the wax unevenly. Position the candle in a calm, sunny location to allow it to burn thoroughly.
4. Use good quality candles
Choose candles from a reputable manufacturer that uses a balance of wax, wick, and container. A wick that is too small will not produce enough heat to melt the wax on the sides.
How to Fix Candle Tunnelling
When candle tunnelling has already occurred, it doesn’t mean that the candle can’t be saved. Here are some simple but effective ways to fix candles that melt unevenly and form tunnels in the middle.
1. Aluminium foil hack
Wrap the top of the candle in aluminium foil, leaving a hole in the center to allow oxygen to the flame. Burn the candle for 1–2 hours; the heat from the foil will help melt the wax on the unburned sides. Once the pooling is even, remove the foil and the candle is ready to use as usual.
2. Use a heat gun or hair dryer
Direct the heat from the heat gun or hair dryer to the surface of the candle until it is even. Make sure the distance is not too close so as not to damage the wick or candle container. This is a quick and practical way, especially to fix uneven surfaces.
3. Make a manual pooling with a hot spoon
Heat a metal spoon, then use it to melt the wax on the high sides so that it blends with the melted area. This is suitable for small candles that cannot be handled with foil or a heating tool.
Choosing the Right Candle to Avoid Tunneling
Choosing the right candle from the start is an important step to prevent candle tunnelling. Not all candles are created equal, so it’s important to pay attention to the type of candle, the size of the wick, and the base material. Larger candles should have more than one wick for more even burning. In addition, candles made from beeswax are known to have a higher melting point and are usually moulded with premium quality, making them more durable and tend to burn more evenly than regular paraffin candles. Beeswax candles also produce a soft, natural scent and are more environmentally friendly. By choosing a quality candle and the right design, you can enjoy the light and scent of your candle without worrying about tunnelling in the middle of its beauty.
By understanding what candle tunnelling is, what causes it, and how to prevent and fix it, you can enjoy your favourite candles to the fullest without having to throw away the candles that haven’t burned out. So, before you light your next candle, make sure you’ve implemented the tips that have been discussed so that every flame created is truly valuable and radiates warmth perfectly.
