I’m sure you’ve had a candle “tunnel”, or not burn the wax all the way out to the edge, leaving a ring of wax as the flame works its way down through the candle. This mostly happens with container candles in apothecary jars or hurricane-type packaging.
The best way to prevent tunneling is to burn candles in a draft-free room and to make SURE the first time you burn it, you can let it burn for 2 hours or so. I think the longer a candle is left to burn at one time, the better it burns and the less tunneling. But, sometimes it’s a manufacturing issue – the type of wax and the wick size are incompatible, and the candle manufacturer should have “wicked up” or moved up to the next bigger size with that particular wax and fragrance.
Anyway, I have a very good candle that started to tunnel pretty bad this winter. It’s finally burned down to the last inch of wax or so, and I devised a way to fix the tunnel. You will need:
electric candle warmer
disposable plastic tub (like an old yogurt or butter container), washed and dried
Take the candle in question and place it on the electric candle warmer for about 45 minutes. This is just enough time to watch an episode of The Wire or some other great TV, so hook it up nearby and keep an eye on it. The wax at the bottom should completely liquify, and the wax on the sides (the tunnel) should be soft as well. If it’s a complete ring, cut it in half with the plastic knife on one or both sides, and extract the C-shaped pieces and leave them in the plastic tub. treat these like wax melts or tarts. Now, the candle can either be finished on the electric warmer or burned again once the wax has cooled.
