Trimming candle wicks is important! By trimming a candle wick to ¼” before each burn, you will get the optimal burn time over the life of your candle. The trimming of the wick not only helps with burn time, but it also ensures you don’t get any residue or soot from your wick. 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 odorless 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. Keeping your wick properly trimmed will make your Sanari Candle last longer and you will enjoy the benefits of our essential oil blends.
