Guidelines for the Burning of Paschal Candles and Larger Candles
The larger the diameter of a candle the more difficult it becomes to burn it without leaving a wall of wax around the edge of the candle. The wick size should be large to enable sufficient heat to melt out to the edge of the candle. If this is not the case, the candle will not burn quickly enough and result in wax running down the candle or the unburned wax being sucked up the wick which will cause the candle being smoky.
However, if the wick is too thin it will not create sufficient heat to melt the wax. Neither wick options are perfect and therefore manufacturer's created a medium wick to avoid most of the problems.
There will always be factors that affect the burning of candles from draughts to summer heat and storage of candles but most importantly once the candle has been extinguished and the wax has set but is still warm, trim the wax wall around the circumference of the candle with a sharp knife leaving approximately a 1/4” high wall for the next lighting.
Also, bear in mind that large diameter candles 2” and over should be burned for a minimum of one hour at a time to allow the candle to melt and perform as it is designed too.
EXTREME CARE MUST BE TAKEN AT ALL TIMES TO ENSURE THAT CANDLES ARE BURNT CORRECTLY AND STANDING ON AND IN A SAFE ENVIROMENT. DO NOT LEAVE BURNING CANDLES UNSUPERVISED.
