Why isn't my candle burning evenly? | Candle tunneling explained

Why doesn't a candle burn evenly?

The most common causes are:

• Too short burning time – especially the first time

• Wrong wick – one well-matched wick is essential

• Drafts or air currents

• Wick not the correct length (ideally ± 5 mm)

Why one wick is better

A candle with one correct wick burns more calmly, melts evenly to the edge, and prevents smoking. Multiple wicks in small candles disrupt the burning process.

Repairing a tunneled candle

• Let the candle burn longer until the entire top layer is liquid

• Use aluminum foil around the edge to retain heat

• Trim the wick before each burn

Conclusion

A well-designed candle burns evenly, cleanly, and calmly. This way, you get the most out of its scent, ambiance, and burn time.
