Wood wick candles are fabulous as they have a much greater scent throw than traditional cotton wicks, they look beautiful and sound lovely. However, if you are new to using a wood wick candle, they can be tricky and there are a few things to be aware of, to ensure you get the best out of your candle.
1) On first use, you must allow the wax to melt to the edges of the jar. This will create a wax-burning memory and encourage this pattern of even burning. If you do not allow the wax to melt to the edges on fist burn, you could end up with 'tunneling' where a hole forms around the wick and the candle only burns in that spot on further uses. Eventually this will mean that oxygen cant get down into the formed hole and the candle will not stay lit.
2) Always, always keep your wick trimmed, after burning always remove the charred uneven edges with a pair of scissors (nail clippers are also a great tool for the job). This will stop your flame burning wild, and will enable the wax to dampen the wick to get the best burn next tie (don't forget, its the wax that fuels the flame). This will also stop ugly charred wick from spoiling the look of your candle if it contaminates the melted wax. Your wick needs to sit below 5mm.
3) Keeping your candle lit. If your candle wont stay lit, this is usually because its drowning in the wax, try to tip out the small pool of wax that has melted around the wick, or blot it with some tissue (when the wick is not lit!) which will enable your wick to breathe, you may need to repeat this step until you are satisfied that the wick is staying lit.
4) Safety. Please follow the candle care instructions that come with your candle. do not ever leave your candle unattended, and never burn it for longer than 4 hours at a time, doing so could cause the wax and jar to overheat.
