Candles have a few variables that can dramatically speed up burn time. A candle of this size has a burn time range between 70 to 80 hours, and where your experience falls within that range comes down these few tips.
Melt to the edges on first light
When you first light your candle, leave it burning long enough so that the wax melts right the way to the edges, usually 1-2 hours. Candles have memory, and a first burn like this avoids tunneling with future use.
TRIM YOUR WICK
Long wicks accelerate burn time of a candle. Keeping your wick trimmed after each use to 4-5mm in length gives best results. Use a pair of scissors or even better a wick trimmer to make it easy. Wick length is important, as if its too long, your candle will burn through the wax faster; too short and you don't get a good melt pool, which means less fragrance being emitted.
DON'T BURN IT ALL DAY
Burning all day is referred to as 'power-burning' and its not the best for your candle. The recommended usage of a scented candle is 3-4 hours. The fragrance in the air will linger long after this and give you many more future uses.
WIND ACCELERATES BURNING
Positioning the candle under a heating vent or in drafty area just feeds the flames more oxygen, which makes fire burn faster, increasing the burn rate. Place it somewhere away from drafts. The fragrance propagates better in these spots too.
PUTTING IT OUT
If you don’t have a snuffer to put it out, simply put the lid on. It will go out almost immediately, the wick won’t smolder and the smoke wont overpower the fragrance in the air.
PUT IT ON A SAUCER
Despite the lovely thick bases my glassware has, as the candle nears its fleeting end the base can get quite hot. If you are positioning your candle on a precious antique sideboard or similar, its wise to put a saucer or something underneath it just to be safe.
AND MOST IMPORTANT - DON'T SAVE IT FOR SPECIAL
We’re on this earth for such a short time, so every single day is special. The best thing about finishing a candle is you get to try a new fragrance when you replace it!
