There have been questions on how long particular candles burn once you make them. In my search I found some information that may help you with that question.
According to Cape Candle, Beeswax Honeycomb Candles are hand rolled and are the tightest rolled, longest burning in the industry. For pillars candles burn approximately 3 hours per inch.; tapers burn approximately burn 40 minutes per inch; beeswax solid tapers burn approximately 1 hour per inch.
As for soy candles, Joy Candles says that soy candle burn times by group. As a general rule soy candles burn about 8 -9 hours per ounce of wax. All burn times are approximate, they are affected by several factors, including drafts improper wick height, etc. For example, a 2 ounce votive candle will burn approximately 16-18 hours. I would say your times may vary. Soy will burn up to 30% to 50% of compariable paraffin wax candles.
