It is important to trim the wick, before it's first burn. Ideally it should be trimmed to approx 5mm, before every burn as this will remove any wick debris and also helps to create an even burn. At home, I use a proper wick trimmer. The straighter the wick, the steadier the flame and this should limit sooting/mushrooming of the wick, help the candle to burn evenly and prevent tunneling.
Occasionally you may see the wick split or fall to one side. You should keep the wick trimmed to help it burn cleaner.
The first burn its the most important! If possible the first burn should last between 3-4 hours and candles should not be left to burn longer than 4 hours in one turn. You should always allow the candle to rest before relighting.
A candle will burn best in still air so it is better to try to avoid having a lit candle in a draft as it may start to smoke or push the flame to one side, creating an uneven burn.
Open flames require caution. Please be sure to place your candle on a heat resistant surface away from drafts, other heat sources and anything flammable.
It’s time to replace your candle when you only have 1cm of wax left and you should make sure that you leave at least a 10cm space between candles.
Keep the candles well out of the reach of children, vulnerable adults and animals. Never leave a burning candle unattended and always extinguish the flame completely.
You should try to use a wick snuffer or a spoon to put out your candle as it’s much safer. If you can avoid blowing out candle this will reduce the possibility of sparks or hot wax being blown into the air and the wick may continue to glow and emit smoke.
Double-check that your candle has fully extinguished before leaving it unattended.
Please also allow the candle wax to cool completely before moving it. The glass may still be hot long after the flame has gone out, so be careful.
