Calculating Burn Time

How do I calculate the burn time of my candles?

 

Amount Consumed (Original wt. - wt. After Burning) ÷ Hours Burnt = Hourly Burn RateOriginal wt. (minus wt. of container) ÷ Hourly Burn Rate = Approximate Burn Time

 

Please Note: If you are testing a container candle make sure to subtract the weight of the container from the weight of the whole candle before dividing by your hourly rate. Also note that the first burn cycle is always a little off because the wick is not yet completely saturated with wax, color, and fragrance.
