Candles are a popular way to add ambience to any space, but they can also present problems, such as tunnelling.
Tunnelling is when a candle burns down the centre, creating a tunnel-like hole, leaving wax on the sides of the jar unused. In this blog, we'll discuss why tunnelling occurs in soy candles and what steps you can take to avoid it.
Why does tunnelling occur in soy candles?
Using too small of a wick: If the wick is too small, it will not be able to handle the amount of wax being burned, leading to tunnelling.
Not allowing the candle to burn long enough: If a candle is not allowed to burn long enough, the wax will not be able to fully melt and will form a tunnel.
Cooling too quickly: If a soy candle is allowed to cool too quickly after being lit, the wax will harden and trap the wick, leading to tunnelling.
How to avoid tunnelling in soy candles:
- Choose the right wick size: Choose a wick size that is appropriate for the size of the candle and the type of wax you are using.
- Allow the candle to burn long enough: Make sure to allow the candle to burn for at least the recommended time, the first time you light it to ensure an even burn. (See our recommended burn time here)
- Trim the wick: Before lighting the candle, trim the wick to 5-10mm. This will help to prevent the wick from getting too long and creating a tunnel.
- Avoid drafts: Avoid burning the candle in a drafty area as this can cause the wax to cool too quickly and lead to tunnelling.
In conclusion, tunnelling in soy candles can be prevented by choosing the right wick size, allowing the candle to burn long enough, trimming the wick, and avoiding drafts. By following these simple steps, you can enjoy a beautiful and long-lasting soy candle experience.
