Additives

Additives such as hardeners for the wax affect the burn time of a candle. Also, excess amounts of added scents tend to do the candle burn faster.

Environment

The environment is also vital factor in a candle’s burn speed. Factors such as wind, humidity, approximately temperature, etc., can impact the rate of burning, which have to be considered while conducting any type of experiment.
