(It is still important to not leave the candle unattended)
You can invest in a handy little tool called a wick trimmer, this is used to cut the wick of the candle as this should be done on all candles. If the candle is new then the wick needs to be as close to 1cm as possible, I’m not suggesting that you get the ruler out to try and get the exact measurement. This just prevents soot forming within the candle. You are also supposed to cut the tip of the wick once it has finished burning and has cooled down, this prevents smoking on the next burn, as well as stopping the glass of the candle jar burning.
If you own candles it also very important that fire safety in in your mind at all times whilst the candle is burning. As you don’t want to be putting the candle near any loose or hanging materials such as curtains, bed sheets or artificial flowers in my case. Candles should also be kept away from any drafts.
Whilst we’re talking about fire safety, it is also very important that you don’t try to move the candle whilst it is lit, especially if the jar is glass as it retains heat and it will burn your hand.
It also important that candles aren’t left in the reach of children or pets, as it could easily break, and I’m sure no one wants a broken candle to deal with, and as I mentioned earlier don’t leave a lit candle unattended.
If you do notice soot coming from the candle then it is a good idea to put the candle out, wait for it to cool and the wipe the jar with a clean damp cloth, as this will stop the glass from showing signs of burning. This is where the wick trimmer that was mentioned earlier will come in handy, as the tip of the wick will have to be cut to stop the soot from forming.
As someone who has numerous shelves and candles on the shelves, it is important to not let the candle burn, especially if the space between the candle and the shelf above it isn’t that high, as that shelf will get hot and you could end up burning it.
If the candle is scented leaving it in direct sunlight is not a good idea, as it will alter the scent, and may spoilt it too! Candles should be kept in a cool dry place when they are not being burnt.
