Tunnelling and how to avoid it...
Share
Tunneling in a candle refers to the phenomenon where the candle burns down the centre, leaving a ring of wax around the edges of the container or candle holder. This happens when the candle's wick is not able to melt the entire surface of the wax evenly, creating a tunnel-like appearance as the candle burns. The result is wasted wax along the edges and a less efficient burn, as the candle does not reach its full potential in terms of both burn time and scent throw.
- The most important factor in preventing tunneling is to burn the candle long enough to create a full melt pool across the top.
- Regularly trim the wick to about 1/4 inch before lighting the candle. This helps maintain a steady, even flame.
- Drafts can cause uneven burning and contribute to tunneling. Ensure the candle is placed in a steady environment.
- Keep your candle clean and free of debris, as any particles or wick trimmings that fall into the wax pool can create an uneven burn.
