Keeping your wick properly trimmed will save you money by making your candle last longer and will prevent your candle from smoking….. you know, that nasty soot that turns your jar black….
The fragrance that comes off a scented candle into your room actually evaporates out of the liquid wax pool on top of your candle. The fragrance and wax burned up by the candle flame turns into odourless carbon dioxide and water vapor. So the candle flame’s only job is to create that liquid wax pool. A little flame does that job very well. A big flame just burns up your candle faster than need be and burns up fragrance instead of letting you smell it.
If the wick is too long, the combustion process in the candle flame is altered and it produces carbon black instead of carbon dioxide. The carbon black will stick to anything it comes into contact with, including your candle jar, your walls, your ceiling…… you get the idea.
Scented candle wicks should always be trimmed to 1/8” above the surface of the candle. Before you clip the wick, you need to remove that little “hump” of wax right around the wick of the candle. This little hump can often be 1/8” tall and if you do not remove it before you trim the wick…. the wick will be too long!
