What burns fastest a thick fat candle or a thiner candle?
The thickness of the wick mostly determines the burn rate. The rate, as used above, is the speed with which the candle wax is consumed, not the rate that the candle burns downward.
Does the color of the candle affect the amount of time a candle will burn?
no, actually it depends on the wick of the candle. the color has nothing to do with it. A candle with a straight wick burns better and longer than a candle with a crooked wick. Also the wax has a lot to do with it. Wax is the most important ingredient that makes a candle burn faster. soft wax has a higher oil content and lower melt temperature; therefore, it burns faster. Candles in jars have a soft wax, and pillar candles have a hard wax. the longest burning candles are pillar candles made of a blend of beeswax and paraffin. To sum it up: color makes no difference at how fast a candle burns. black candles burn no faster than white candles. Wick size is the primary factor determining the candle burning rate. the bigger wick will deliver more fuel to the burning flame.
Is it possible to burn the candle at both ends?
Yes. The wick goes all accross the candle. You simply burn the bottom of the candle a little and the wick will stick if the bottom burns enough. So you lay the candle and stick it on a square object and light both ends of the candle.
