Temperature of the surroundings

Tip: Store candles away from cold sources such as near windows in the winter. If you keep a candle outside in the cold or near a cold window, the wax will be cold and will melt slower when burning than if the wax was room temperature (65-75 degrees F). This may result in a small flame and wax being left on the sides.

          Wick not centered

Tip: If you notice that the burn pool is not centered, while the candle is burning use a non-flamable item (such as a metal nail file or silverware) and gently push the base of the wick toward the correct direction.

 

Candles, no matter the type, may burn a bit differently due to many factors. A common complaint about candles is that the flame is small and that they have small burn pools. In other words, they burn a small hole down the middle of the candle instead of melting all the way out to the sides. Not only does this reduce the amount of light created by the
candle, but it significantly reduces your total burn time when a bunch of wax remains.

Primary causes of this include the following:

Burning Tips

 

 

 

        The length of time the candle is burned at each sitting is not long enough.

Tip: Try to burn candles long enough each time so that the entire top layer melts to the sides before being extinguished.  (This pertains mostly to candles in containers versus freestanding ones.)  This is of most importance the first time you burn a candle in a glass container, because it will look nicer as the candle burns down to have it clean and clear on top. A general guideline is to try to burn candles at least an hour each time for each inch the candle is in diameter.  This way the wax has a chance to melt down from the sides. Equally important, each time a candle is blown out, the top part of the wick smokes away, leaving a shorter wick and more wax for the next burn, so the less number of times you extinguish it, the better, if you are only burning the candle a few hours or less each time. (If you burn candles in long sittings, over about five hours each time, you may find that the wick becomes rather long. If this is the case, your candle will look nicer and last longer if you trim the wick, which can be done carefully while it's burning, every four hours or so. Usually with our candles, cutting it in half works well, which is down to an 1/8-1/4 of an inch.)
